Covid-19 News

  • does JR understand any of the terminology

    like oncogenes or epigenetics?

    Okay, if we are asking rhetorical questions --


    Do you understand that every other expert, textbook and public health agency disagrees with this person? That every biologist from the 1960s on has said that RNA cannot affect the nucleus (except a retrovirus, which this is not)? Do you understand that public health experts and virologists know what they are doing, and they have good reasons for believing the vaccine is not dangerous? If you doubt they know what they are doing, you need to look at what they have accomplished. In many countries, these agencies have succeeded in limiting COVID deaths to a level they cannot even be measured in excess deaths. Results count.


    Just because you have found one expert who disagrees with the establishment, and you happen to know some of terminology this person uses, that does not prove that 99.9999% of other experts are wrong, and all textbooks are wrong.

  • COVID-19 Vaccines Produce Alarming Number of Cardiovascular Adverse Events in Europe

    Here the preprint: Suspected Cardiovascular Side Effects of two Covid-19 Vaccines 010821.pdf


    The WHO and other public health agencies gave detailed instructions to avoid massive deaths,

    First WHO advice: Do not stop traffic from China!!! Did (could have) save 500'000 US deaths...

    Leaders in countries such as Japan and Korea did what the WHO recommended, and had only a few thousand deaths. Per capita between 30 and 100 times less deaths than the U.S. In Japan and Korea there were no excess deaths in 2020.

    You missed out Switzerland. We had no excess mortality in 2020. Also none for people age < 65 in 2021 what else can you expect? We are not the criminal states of USA,UK,EU with outdoor masks and curfew. We did allow people to get soft CoV-19 infections outdoors, what did help to immunize the larger part of the population.

    All others had 3x more deaths during the third wave!


    You live in a death cult state! that kills people for profit!


    The argument for it is that it is much more difficult for vaccine-evasion to happen in the spike region - since the spike needs to work.

    You do certainly not follow the science. The above has been refuted by the reality....Spike mutations are among the most frequent. But after Delta there is no more room for improvement!

  • Do you understand that every other expert, textbook and public health agency

    No,

    Every... is one of those rhetorical generalisations.

    There's much more than one..

    Is cherry picking experts another Georgian pastime

    Like generalisation?

  • From:https://www.biorxiv.org/conten…1.07.29.454333v1.full.pdf (first linked above)


    We also compared the affinities of pairs of antibodies obtained from conserved clones between 2

    and 5 months after vaccination. Conserved clones obtained at 2 and 5 months from vaccinated

    individuals showed an average 1.9-fold increase in affinity (p=0.03, Fig. 4c). In contrast, a

    comparable group of conserved clonal antibodies obtained from convalescent individuals 1.3 and

    6.2 months after infection showed an average 24-fold increase in affinity (p=0.002, Fig. 4c).


    This answers why a natural infection protects you much much better than the RNA gen therapy.


    But this is science...

    For dummies: affinity means how well the antibodies fit the target (spike).

  • Move to Quiet Doctors with Risk of Pulling Medical Licenses Over ‘Misinformation’


    Move to Quiet Doctors with Risk of Pulling Medical Licenses Over ‘Misinformation’
    The stakes against purported “misinformation” get even more controversial as the Federation of State Medical Boards’ Board of Directors released a
    trialsitenews.com


    The stakes against purported “misinformation” get even more controversial as the Federation of State Medical Boards’ Board of Directors released a statement declaring that physicians and other health care professionals involved in the dissemination of COVID-19 vaccine misinformation and disinformation via social media platforms, online and in the media, face grave potential actions, including the loss of medical license.


    What follows is a direct statement from the FSMB:


    “Physicians who generate and spread COVID-19 vaccine misinformation or disinformation are risking disciplinary action by state medical boards, including the suspension or revocation of their medical license. Due to their specialized knowledge and training, licensed physicians possess a high degree of public trust and therefore have a powerful platform in society, whether they recognize it or not. They also have an ethical and professional responsibility to practice medicine in the best interests of their patients. They must share factual, scientifically grounded, and consensus-driven information for the betterment of public health. Spreading inaccurate COVID-19 vaccine information contradicts that responsibility, threatens to erode public trust in the medical profession further, and puts all patients at risk.”


    For more information about how state medical boards and the FSMB respond to the COVID-19 pandemic, visit FSMB’s webpage dedicated to providing resources and knowledge to states and the public about COVID-19.


    What is Misinformation?

    As TrialSite has found, the quest to determine what is, in fact, misinformation may vary depending on the interests behind the interpretation. For example, TrialSite has been censored by social media for simply reporting on ivermectin studies or reporting when a nation, such as Slovakia, accepted the use of ivermectin in that country. That was deemed “misinformation” by Facebook and YouTube even though it was 100% factual. Consequently, this latest news serves as a cautionary tale to physicians and health care professionals that the prospect for intensifying censorship activity is a real and tangible threat to doctors and health care professionals. TrialSite suggests physicians, for example, retain attorneys to ensure that whatever they are declaring can be defended.


    About the Federation of State Medical Boards

    The Federation of State Medical Boards (FSMB) is a national non-profit organization representing the medical boards within the United States and its territories that license and discipline allopathic and osteopathic physicians and, in some jurisdictions, other health care professionals. The FSMB serves as the voice for state medical boards, supporting them through education, assessment, research, and advocacy while providing services and initiatives that promote patient safety, quality health care and regulatory best practices. The FSMB serves the public through Docinfo.org, a free physician search tool that provides background information on the more than 1 million doctors in the United States.

  • There is only a tiny bit of Viral RNA in the Pfaccine..

    RB - I know very well you understand this stuff, which is why I find your posts disingenuous at least.


    The mRNA vaccine RNA you know full well codes for spike proteins, a structural element of the virus surface, not any of the viral proteins that actually allow the virus to reproduce. You know that - right?

  • You do certainly not follow the science. The above has been refuted by the reality....Spike mutations are among the most frequent. But after Delta there is no more room for improvement!

    W - I don't like to say this to you but both these statements are completely unevidenced. The second one is 99% false (never bet against Darwin). The first one is vague and probably (if tightened into some statement that could be measured) false. Since, unlike you, I don't like to say things without evidence, and i have not looked at the research on this (nor do I intend to - it is not very interesting to me) I can't prove that. But I rest certain that you never prove any of the things you say here, most of which are wrong.

    You missed out Switzerland. We had no excess mortality in 2020.


    Consistent with the timing of known peaks of covid-19 infection, many countries had major waves of excess deaths in the northern hemisphere spring (March-May) and in autumn-winter (October-December). In spring, the level of excess deaths was particularly high (with some weeks of >50% excess deaths) in Italy, Spain, England and Wales, Scotland, Northern Ireland, Belgium, and the Netherlands. In autumn-winter, levels of excess deaths were particularly high in Austria, Belgium, Czech Republic, Hungary, Italy, Lithuania, Poland, Slovakia, Slovenia, and Switzerland. Within countries, we found little evidence of a difference between men and women in trends over time in the proportional increases in excess deaths in 2020.

  • Watch ..Alexandra.again

    She's much more than just one... go find out what her job was

    Indeed, she is a shining light in the anti-vax movement in France. is it not a shame that scientists, just like anyone else, can go down the road of being faith-keeping political warriors? Somehow it would be nice to think they had a higher standard than common mortals, but alas they are but human...


    Two of the main instigators of the recent campaign in Mauritius against Covid vaccination are French people settled in Mauritius. The third is the French embassy’s doctor. We mention this national connection because it is no coincidence that France is the epicentre of anti-vaccine campaigns. Dr. Alexandra Henrion-Caude, known world-wide as “the muse of the Covid conspirators”, actually sat on the Economic Development Board (EDB), which just about runs the country now that the Ministry of the Plan is “privatized”. Luckily she is no longer on it; EDB runs the vaccine bookings! Ms. Henrion-Caude’s husband is a Sun Resorts hotel boss and, together with her, has opened a private lab here. She also gives lectures at the Institut Cardinal Jean Margeot. In France, she used to be a respected researcher who, instead of remaining in the logic of science, followed her political ideas as a right-wing Catholic. It is important to put on record that the Pope, by contrast, encourages vaccination. He calls it an “ethical obligation”. Strong language. He makes the point of opposing the line of high-profile Catholics like Ms. Henrion- Caude who say, in order to manipulate believers, that human foetuses are supposedly used in vaccine manufacture. She is a slippery character to make that suggestion. Le Parisien thinks so too: “Pendant 1 h 20, ce vendredi ... [Dr. Alexandra Henrion-Caude] expose au Parisien son parcours et ses convictions, brûlant de convaincre de sa légitimité. Le lendemain, elle refusera par mail (avec copie à son avocat) que ses citations soient publiées.” (Le Parisien 30 Mai 2021). Le Monde says of her, “Mme Henrion-Caude est installée depuis plusieurs années à l'île Maurice, où elle a lancé, en 2017 avec son époux, un mystérieux laboratoire de recherches ..” Yahoo StyleFrance, says on 15 June, “En effet, elle vit depuis 2017 à l'île Maurice où elle a fondé, avec son mari, un laboratoire dont le but est ‘d'établir le lien, qui fait actuellement défaut entre la médecine traditionnelle et la science innovante’”. She was also in contact here with disgraced former President of the Republic, Ms. Ameenah Gurib-Fakim, also a scientist with a traditional medicine bent, and who resigned after the Platinum Card scandal in the Alvaro Sobrinho affair; she and Sobrinho, ironically, had announced jointly that Bill Gates, who finances vaccines and who is the anti-vaccination campaign’s scapegoat, was to finance them – by the billion in dollars!



    In depth:


    De l'Inserm aux théories complotistes sur le Covid: qui est la généticienne Alexandra Henrion-Caude?
    Généticienne de formation, Alexandra Henrion-Caude était directrice de recherche à l'Inserm jusqu'en 2018. Elle a été épinglée plusieurs fois depuis le début…
    www.bfmtv.com


    Prestigious CV

    Before breaking into the anti-ax, anti-sanitary or anti-mask spheres, Alexandra Henrion-Caude displays the CV of a seasoned scientist, who completed her university honorum course . Aged 52, she notably holds a doctorate in genetics obtained in 1997 at the University of Paris VII, we learn by reading a portrait devoted to her, in 2013, by the magazine Sciences & Santé , published by the Inserm (National Institute of Health and Medical Research), on the occasion of his obtaining the prestigious title of Eisenhower Fellow , awarded at the time by the former US Secretary of State to George W. Bush Colin Powell .

    The geneticist was then research director at Inserm. In this portrait, we also learn that her thesis director was none other than the geneticist Axel Kahn, against whom she filed a complaint for defamation not long ago.

    A procedure which is worth to the professor to be indicted (almost automatic in the event of complaint for defamation). Figure of the League against cancer, which he recently retired after announcing to be suffering from an incurable cancer , Axel Kahn reported his indictment on Twitter on May 25, where he points to "the incredible derivation of a formerly quality researcher by a fundamentalist then sectarian logic ".

    Alexandra Henrion-Caude also practiced in the United States, at the Children's Hospital in Los Angeles. Science & Santé also attributes to him in 2012 the discovery of "the implication of non-coding RNA in genetic diseases".


    Participant in the documentary plotter Hold-Up

    Alexandra Henrion-Caude also appears in the documentary with conspiratorial hints Hold-Up , broadcast online last November. She appears in particular alongside Christian Perronne or Silvano Trotta "who thinks that the Moon is hollow and that we have never landed", pointed out at the time to BFMTV.com Tristan Mendès France, associate lecturer at Paris-Diderot University, in charge of digital cultures, collaborator of the Observatory of conspiracy.

    The geneticist there affirmed, for example, that the vaccines against Covid-19 had been the subject of an "acceleration of a vaccine development procedure skipping phases 3, never done before". A false assertion, as the AFP Factuel had shown .

    The researcher, now rejected by her peers, is also displayed on the FranceSoir site, a vestige of the post-war daily France-Soir , which no longer has the status of a press company, pointed out Liberation in November. For example, she signed an appeal with other personalities on May 9, notably asking for "a more cautious approach to mass vaccination".

    Several infox

    She also appears regularly on the web TV, TV Libertés, which defines itself as the "1st news channel". In January, AFP Factuel pointed out in an article that in an interview with this far-right channel, she had claimed that messenger RNA vaccines (such as that of Moderna and Pfizer - BioNTech) induced a genetic modification. A false declaration, as also shown by the AFP verification service.

    In February, AFP pointed out, it also published a curve of deaths due to Covid-19 in Seychelles, drawing a parallel with that of vaccination in the Indian Ocean archipelago. What the Seychelles government had denied following the proliferation of this fake news , indicating that the deceased had not received a vaccine.

    The geneticist is also the subject of a file on the site of the Observatory of conspiracy . We learn in particular that she is a member of the honorary committee of the Association of Christian Scientists.

    Last October, Inserm dissociated itself from its former researcher, and pointed out to LCI that Henrion-Caude had left the institute in 2018 for "reasons of personal convenience" and that his remarks concerning the Covid pandemic- 19 were "by no means those of Inserm".


    She has gone far. far down the conspiracy road...


    Alexandra Henrion-Caude - Conspiracy Watch | L'Observatoire du conspirationnisme
    Alexandra Henrion-Caude est une généticienne française devenue en 2020 une figure de la complosphère « coronasceptique ».
    www.conspiracywatch.info


    Interviewed by Élise Blaise on the far-right webTV TV Libertés on July 31, 2020, Alexandra Henrion-Caude vehemently criticizes the “conflicts of interest with pharmaceutical companies” of which her colleagues - whom she does not mention by name - would be made guilty ( "they do not bite the hand that feeds them" she accuses) and protests against the confinement and the wearing of the mask. A video seen nearly 600,000 times and widely relayed on the complosphere, by sites such as Les Moutons enrrages , Réseau International , Wikistrike , Égalité & Réconciliation , L'Échelle de Jacob, Breizh-info or Alterinfo.net or personalities like Etienne Chouard ).

    The former research director at Inserm further explains that our immune system is “a health capital […] which is maintained by playing sports, and therefore by avoiding being confined for two months; by having good ventilation, good oxygenation, that is to say by avoiding wearing a mask; by having a good diet, that is to say by having the freedom to go out to buy everything you need where it is needed. "

    Regarding the development of a vaccine against Covid-19, Alexandra Henrion-Caude also affirms that "the horror, the horror, the horror [sic] is that we have arbitrarily chosen Africa of the South to set up a forced vaccination in centers kept secret, and therefore there are student movements who rebel, but who are obviously repressed, to denounce the fact that they are really used as guinea pigs . " Alexandra Henrion-Caude here refers to the clinical trial to test a vaccine against the Covid-19 began June 24, 2020 in South Africa . However, this country was not "arbitrarily chosen": it is the country most affected on the African continent by Covid-19 and also one of the most affected in the world by AIDS (some 7 million people live with HIV), so the vaccine against the coronavirus could protect this particularly fragile population. Conducted under the supervision of a University of Johannesburg, this vaccine trial was carried out with the participation of 2000 volunteers (including 50 HIV positive) and on a voluntary basis. Contrary to what the geneticist said, there is no indication that the selected patients would be vaccinated under duress or against their will. In addition, as the Swiss newspaper Le Temps explains, the vaccine concerned, ChAdOx1 nCoV-19 (which was previously administered to 4,000 people in Great Britain and is also to be administered to volunteers in the United States and Brazil), has been tested in three secret locations, not because anything horrible or shameful would take place there, but to prevent possible incidents in a context marked by mistrust of vaccination, conspiracy theories around the pandemic and the controversy heightened by the remarks made in April by a doctor at Cochin hospital in Paris .

    In early May 2020, interviewed by Pierre Barnérias , from the ThanaTV YouTube channel [ archive 1 ; archive 2 ], Alexandra Henrion-Caude already denounced the "total irrationality of official explanations around the coronavirus" and promoted, instead of vaccination, the treatment recommended by Professor Didier Raoult. According to her, facing the Covid-19,“The answer is not going to be the vaccine. It is to try to manage the crisis with a number of antivirals. And there we have a winning triptych. There, we have the solution that seems to work wonderfully which was: an antiviral - so it can be herbal, it can be based on antimalarial treatments, anti-malaria such as hydroxychloroquine, but in any case obviously we already need an antiviral in the arsenal […]; the second is an antibiotic which is brilliant, it is azithromycin, which has antiviral efficacy and which we know well, I know well, because it has been used very widely in cystic fibrosis not only because obviously it is antibacterial like all antibiotics, but also because it is anti-viral; and the third agent of the triptych is a little zinc ”.

    In the same interview, she said, concerning the influence of 5G on the coronavirus, "that we do not have much history on 5G but that everything we see on 5G shows that there is has very significant repercussions, especially in diabetics ” .

    Contacted by Conspiracy Watch on August 3, 2020, Inserm indicates that it does not endorse the comments made by Alexandra Henrion-Caude.

    In October 2020, Alexandra Henrion-Caude is one of the founding members of the Bon Sens association from which she is withdrawing, as is the deputy Martine Wonner , a few days after its creation . She is also one of the speakers in the conspiratorial film " Hold-up  " by Pierre Barnérias, broadcast on the Internet in November 2020.

    In a one-hour video shared thousands of times on Facebook on January 16, 2021, Alexandra Henrion-Caude takes up several false information on the Covid-19 pandemic scrutinized by AFP Factuel a few days later.

    On Saturday 23 January 2021, she participated in a private capacity in the demonstration against "coronafolie" organized in Paris by Florian Philippot, former right-hand man of Marine Le Pen at the National Front and president of the Patriots.


    On March 13, 2021, she announced on Twitter that the International Criminal Court (ICC) "accepted" a complaint filed by Israeli lawyers against their government for "violation of the Nuremberg Code" [ archive ]. This false information is based on a fallacious interpretation of a simple "acknowledgment of receipt" sent by the ICC to the authors of the complaint.

    On April 7, 2021, his interview with the business magazine L'Éco austral was announced on the cover. She also gave an interview to the magazine published in March-April 2021 by the traditionalist and conspiratorial Catholic group Civitas .

    On May 22, 2021, she took part in a demonstration in Paris against the health pass, alongside Jean-Marie Bigard and Florian Philippot.




  • Alexandra Henrion-Caude already denounced the "total irrationality of official explanations around the coronavirus" and promoted, instead of vaccination, the treatment recommended by Professor Didier Raoult. According to her, facing the Covid-19,“The answer is not going to be the vaccine. It is to try to manage the crisis with a number of antivirals. And there we have a winning triptych.

    Alexandra may say the things RB wants to hear, but she is not very accurate on COVID stuff:


    https://www.thelancet.com/jour…-2600(21)00263-0/fulltext (and many other studies)


    Like all anti-vaxxers - she starts off with a strong emotional (political? religious?) dislike of vaccines as a medical intervention. She then indulges whatever fantasy is needed to make a non-vaccine route through the pandemic seem best.


    Alexandra Henrion-Caude also affirms that "the horror, the horror, the horror [sic] is that we have arbitrarily chosen Africa of the South to set up a forced vaccination in centers kept secret, and therefore there are student movements who rebel, but who are obviously repressed, to denounce the fact that they are really used as guinea pigs .

    And, like many anti-vaxxers, she leaps to irrational conclusions about the infamy of vaccine trials... it shows a rather closed mind on the topic - not someone interested in risk balance calculations!

  • “Physicians who generate and spread COVID-19 vaccine misinformation or disinformation are risking disciplinary action by state medical boards, including the suspension or revocation of their medical license. Due to their specialized knowledge and training, licensed physicians possess a high degree of public trust and therefore have a powerful platform in society, whether they recognize it or not. They also have an ethical and professional responsibility to practice medicine in the best interests of their patients. They must share factual, scientifically grounded, and consensus-driven information for the betterment of public health. Spreading inaccurate COVID-19 vaccine information contradicts that responsibility, threatens to erode public trust in the medical profession further, and puts all patients at risk.”

    TSN does not like this, and then goes on to complain about not being allowed to put its weird pro-ivermectin message onto youtube.


    But this refers only to anti-vaxx disinformation. And it seems fair to me. Doctors are meant to keep people healthy. Spreading misinformation that causes people to avoid vaccination and therefore increases their risk of harm looks to me like medical misconduct pretty clearly.


    The FLCC propaganda is not the same, unless it is combined with a ivermectin works do you don't need to be vaccinated message. I have a feeling TSN might try selling that one too, but it is not necessarily what a pro-ivermectin doctor would do. Anyway convincing people that taking worm-pills stops them from getting COVID is still dangerous misinformation if believed since it might cause them not to take other precautions.

  • Alexandra is asociated with a vaccine misinformation super-spreader web site


    L’Eveilleur Quantique

    144,348 Facebook page likes

    The Facebook page of Jean Pierre Marrigues, a motivational speaker who describes L’Eveilleur Quantique as “a space where quantum physics, neuroscience, epigenetics, neurobiology and energy psychology intersect.”

    Examples of vaccine misinformation:

    • A May 1, 2020, recording of a Facebook live video, in which anti-vaccine advocate and Swiss doctor Christian Tal Schaller made multiple false health claims, including that the COVID-19 “vaccine that they will soon force you to take is a vaccine with a microchip in it in order to control you all.”
    • An Aug. 3, 2020, post featuring a YouTube video produced by NewsGuard Red-rated French site TV Libertés, in which French geneticist Alexandra Henrion-Caude falsely asserted that the COVID-19 vaccine was given by force to human “guinea pigs” in South Africa. A Facebook label warned readers that independent fact-checkers found the content to be “partly false.”

    Asked to comment on the first post, Marrigues told NewsGuard in an email, “We focus on personal development, and we have felt through our pages a general concern. This [Facebook] live was initially intended to suggest food for thought about this phase…. The guest who takes part in this live is a doctor, who gives his opinion and his vision. Everyone is free to take what they want, and to ‘throw away’ what does not suit them. Again, the goal of our pages is to share, not impose, nor create psychosis, let alone fuel the fear that is already everywhere.”

    As for the second post, Marrigues said that Henrion-Caude “gives, beyond her explanations, her scientific point of view. Again, it is sharing a point of view and opinion. I do not know personally if these theories were confirmed or not.” Marrigues added that Henrion-Caude and Schaller “may be controversial today, because they have a different point of view from the majority. However, they are still health professionals. Therefore, for me, they are a ‘reliable’ source.”


    The people running these sites think a person with scientific credentials should be unchallenged and viewed as reliable even when they spread obviously fact-checkable lies. And, alas such people get believed.

  • In autumn-winter, levels of excess deaths were particularly high in Austria, Belgium, Czech Republic, Hungary, Italy, Lithuania, Poland, Slovakia, Slovenia, and Switzerland.

    This statement is wrong! For 2020 Switzerland had no excess mortality! I linked the data - official state site - some weeks ago. Only during the third wave winter spring 2021 we had real excess mortality among people age >65.

    If you look at certain periods within the year you always find excess mortality. E.g. the flu delivers the same or extreme heat in summer.

    Pharma propaganda likes this data to fear the people. But excess mortality is only important over a one years frame. Further even more important is the average age of the excess mortality. This was 84 years in CH. Not so in UK/USA that had a real slaughtering phase!


    The mRNA vaccine RNA you know full well codes for spike proteins, a structural element of the virus surface, not any of the viral proteins that actually allow the virus to reproduce. You know that - right?

    You seem to have real deep knowledge. Do you also know which subpart of the spike is coded in the gen therapeutic agent?

    Further do you know why this dilettantes approach does not generate a stable T-Cell memory?

    W - I don't like to say this to you but both these statements are completely unevidenced.

    You never read papers and thus you are the most awful spreader of lies. You just defend big pharma (FM/R/XXX/B) mafia marketing info!

    And, like many anti-vaxxers, she leaps to irrational conclusions about the infamy of vaccine trials...

    Only cricket brains let themselves inject a untested gen therapeutic agent that they don't need! So you must have many comorbidities.... As we can see from your postings...below ... you deeply suffer from mental troubles.

    TSN does not like this, and then goes on to complain about not being allowed to put its weird pro-ivermectin message onto youtube.

    Note that views expressed in this opinion article are the writer’s personal views and not necessarily those of TrialSite.


    Summary


    As Sars-CoV-2 entered a highly susceptible human population, it has initially been spreading rapidly and in an uncontrollable way. This already explains why Sars-CoV-2 has been evolving rather slowly with no substantial selection of fitness-enhancing mutations occurring over the first 10 months of the pandemic (i.e., between December 2019 and October 2020). More infectious ‘variants of concern’ (VoCs, i.e., alpha [B.1.1.7], beta [B.1.351], gamma [P.1]) started to appear as of late 2020 and led to a steep increase in cases worldwide.


    Molecular epidemiologists have observed that mutations within the Sars-CoV-2 spike (S) protein of these emerging, more infectious lineages are converging to the same genetic sites, a phenomenon that coincided with a major evolutionary shift in the landscape of naturally selected Sars-CoV-2 mutations (1).


    Significant convergent evolution of more infectious circulating Sars-CoV-2 variants is not a neutral, host-independent evolutionary phenomenon that merely results from increased viral replication and transmission but is strongly suggestive of natural selection and adaptation following a dramatic shift in the host(ile) environment the virus is exposed to (1).


    Molecular epidemiologists fully acknowledge that the pandemic is currently evolving Sars-CoV-2 variants that “could be a considerably bigger problem for us than any variants that we currently know in that they might have any combinations of increased transmissibility, altered virulence and/or increased capacity to escape population immunity” (1). This is to say that phylogenetics-based natural selection analysis on circulating Sars-CoV-2 lineages strongly suggests that viral variants resistant to spike (S)-based Covid-19 vaccines are currently expanding in prevalence and highly suspicious of causing future epidemic surges globally.


    Deployment of current Covid-19 vaccines in mass vaccination campaigns combined with the ongoing widespread circulation of Sars-CoV-2 can only increase immune selective pressure on Sars-CoV-2 spike protein and hence, further drive its adaptive evolution to circumvent vaccine-induced humoral immunity. In this regard, the expectation of an increasing number of vaccinologists matches the current observation made by genomic epidemiologists in that S protein-directed immune escape variants are highly likely to further spread and expedite the occurrence of viral resistance to the currently deployed and future (so-called ‘2nd generation’) Covid-19 vaccines.


    To monitor the circulation of hazardous viral variants in the population and to be able to provide unequivocal proof of the immune selection pressure exerted by mass vaccination campaigns and the harmful consequences thereof, there is an urgent need for conducting representative viral sampling on vaccinees, including those who are healthy or only subject to mild disease, and to genetically characterize the variants they shed upon exposure to Sars-CoV-2.


    Conducting a mass vaccination experiment at a global scale without understanding the mechanisms underlying viral escape from vaccine-mediated selection pressure is not only a colossal scientific blunder but, first and foremost, completely irresponsible from the perspective of individual and public health ethics.


    In the absence of vaccines capable of inducing sterilizing immunity, early multidrug treatment as proposed by Prof. Dr. P. McCullough and others (https://pubmed.ncbi.nlm.nih.gov/33387997/), together with global chemoprophylaxis using highly efficient antiviral drugs, will be key to save lives, reduce the hospitalization burden and dramatically diminish transmission of highly infectious or neutralizing antibody (nAb)-resistant escape variants.


    Preamble

    There is currently a lot of confusion in regard of the effectiveness of Covid-19 vaccines with plenty of contradictory reports circulating in the literature and on social media. This in itself is probably providing the most convincing evidence that the pandemic situation is rapidly evolving and is currently transitioning a kind of ‘gray’ zone. A pandemic is typically to be considered a very dynamic event (until it merges into an endemic situation). However, the evolutionary dynamics of this Covid-19 pandemic have now been shaped by human intervention in a way that is completely unprecedented. We do know about the outcome of a natural pandemic but don’t know at all about the outcome of the ongoing pandemic, as the latter has now become a ‘pandemic of variants’. From what follows below (and which is basically a summary of findings made by molecular/ genomic epidemiologists that I put into a broader context), there is, however, one certainty, which is that Sars-CoV-2 variants are rapidly evolving in response to the natural immune selection pressure they are experiencing. Phylogenetics-based natural selection analysis indicates that a substantial amount of the immune selection pressure exerted during this pandemic is directed at the Sars-CoV-2 spike (S) protein, which is targeted by the vaccines. On their journey to adapting to the host(ile) environment of neutralizing antibodies (nAbs), variants further exploit their evolutionary capacity to overcome this S-directed, population-level immune pressure. Hence, in a given vaccination setting and stage of the ongoing pandemic, the success of mass vaccination campaigns will to a large extent depend on the evolving prevalence of increasingly problematic variants. Alternatively, S-directed immune interventions that seem effective in one vaccination setting and stage of this pandemic may not work as well when applied to another vaccination setting or when implemented at another stage of the ongoing pandemic. The observation that the effectiveness of mass vaccination campaigns, as assessed during a pandemic of immune escape variants, oftentimes evolves very differently between countries or regions is, therefore, not surprising. It is only when the population-level selective immune pressure will culminate that variants and, therefore, the effects of these campaigns will start to globally converge to the same endpoint, which is ‘resistance’ to the vaccines. It is only at that very endpoint that all assessments of the alleged ‘effectiveness’ of this experiment will become unanimous and consistent. When exactly this will happen is still subject to speculation. However, as the immune selection pressure in the global population is now ‘massively’ rising and the set of naturally selected, S-directed mutations together with the plasticity thereof dramatically expanding, one can reasonably expect that the edition of a super variant capable of resisting S-specific Abs will be precipitated such as to emerge within the next few months. When second-generation vaccines will be introduced, the virus will only be building upon this versatile foundation of circulating mutations to rapidly circumvent the immune pressure the re-vaccinated population will continue to exert on the S protein.


    “The most important issue here is not whether this particular “super variant” ever arises….” (1)

    It is unbelievable how public health authorities (PHAs) are lagging behind when it comes to understanding the evolutionary capacity of Sars-CoV-2. Or do PHAs and policymakers simply ignore the observations made by world-class molecular epidemiologists? How can they possibly justify mass vaccination campaigns in light of all the scientific arguments pointing to the high likelihood that these campaigns will only expedite viral resistance to Covid-19 vaccines? Why are the scientists who are bringing all this evidence to the PAPER not bringing it to the TABLE? How can they predict that this pandemic is going to evolve even more problematic VoCs and keep silent? Why don’t they set up a forum of independent, knowledgeable experts providing indisputable and unanimously agreed evidence that the rhetoric put forward by the WHO and national health authorities is scientifically wrong? Don’t they realize that keeping silent about the ongoing disastrous – but for now still largely hidden – evolution of the pandemic is only going to provide more ammunition for governments to extend their mass vaccination campaigns such as to reach as high as possible vaccine coverage rates in the population? Why on one hand do molecular epidemiologists seriously consider that resistance to the vaccines may occur as a result of rapidly rising S-directed immune pressure in the population but on the other hand don’t ring the alarm bell? How can they acknowledge the effect of emergent viral variants on the efficacy of Covid-19 vaccines without overtly pointing to the risk that vaccines failing to block viral transmission will further shape the evolutionary dynamics of viral variants? How can they recognize that antibody(Ab)-based therapy (e.g., use of convalescent plasma and monoclonal Ab treatments) in immunocompromised, chronically ill patients promotes long-term viral shedding and may lead to the propagation of variants carrying Ab escape mutations while ignoring the likelihood for a similar effect to occur when mass vaccination enables an entire population to exert immune selection pressure on the very same immunodominant Sars-CoV-2 S protein (i.e., when large numbers of individuals are vaccinated while being exposed to the virus before having developed a full-fledged Ab response)? It cannot be that they don’t understand the disastrous consequences viral resistance to Covid-19 vaccines would imply! It cannot be either that they didn’t learn that the kinetics of natural selection of immune escape mutations are much slower (or even non-existent as in the case of the Influenza pandemic of 1918!) in the presence of naturally elicited immunity. Or don’t they realize that the type of immune priming following natural Sars-CoV-2 infection is very different from the one that results from prophylactic immunization with S-based vaccines? It is difficult to imagine they would not comprehend why under conditions of natural viral infection and transmission during a pandemic, the chances for freshly infected, immunologically naïve or previously infected subjects to become re-infected on a background of suboptimal S-specific Abs are much lower than for vaccinated people to become exposed to Sars-CoV-2 while not being armed with a high enough titer of full-fledged S-specific Abs.


    In other words, if molecular epidemiologists would only realize that immune selection pressure exerted by S-directed Abs occurs much less frequently during a natural pandemic than in the course of mass vaccination campaigns, they would probably figure among the best-placed scientists on earth to warn against the high likelihood for this virus to evolve immune evasion and, ultimately, to resist vaccinal nAbs as a result of mass vaccination. At any rate, they all recognize the need for careful systematic surveillance of the ongoing evolutionary immune escape, which currently translates in an enhanced expansion of variants comprising mutations that further converge as they continue to adapt to rising population immunity in general and S-specific Abs in particular (1).


    Although population cohorts exerting selective S-directed immune pressure, (i.e., now increasingly consisting of vaccinees!) provide a breeding ground for S-associated immune escape mutations, health authorities seem to no longer be monitoring viral shedding and genetic characterization of viral samples in healthy or only mildly ill vaccinees. This is, of course, highly problematic as even asymptomatically infected vaccinees are known to shed the virus and are now granted more freedom of movement and adhering less to social distancing measures. In this way, we are currently largely incognizant of the true prevalence and distribution of new variants and the speed at which they spread in the population. However, epidemiologists are not raising their voice to put an end to this grave public health negligence, even though they clearly seem to disagree with this practice: “As antigenically different variants are continuing to emerge, it will become necessary to routinely collect serum samples from vaccinated individuals and from individuals who have been infected with circulating variants of known sequence” (3); and further: “Defining these dynamics, and their potential influence on vaccine effectiveness, will require large-scale monitoring of SARS-CoV-2 evolution and host immunity for a long time to come” (4).


    In the meantime, the WHO and their advising ‘experts’ are still preaching the very same mantra that the more we vaccinate, the less the virus can replicate and hence, the lower the risk that VoCs will arise and become dominant in the viral population. Is it this mantra of mass vaccination that leads PHAs to conclude that monitoring of viral shedding in vaccinees has become obsolete? However, their simplistic interpretation of viral transmission dynamics would only apply to conditions of neutral genetic drift as occurring during the early phase of a pandemic, i.e., in a population of immunologically unprimed susceptible subjects that do not exert significant positive selection pressure on the virus prior to its host-to-host transmission (2). However, at this stage of the pandemic where a multitude of variants, including several VoCs, are already circulating, the real global health concern is no longer about the likelihood for yet another problematic variant to emerge but rather about the ongoing population-level selection pressure that is now driving particular mutations of concern to expand in prevalence. Ignoring the positive selection signals that are now increasingly observed within nAb-binding S domains inevitably leads to an underestimation of the evolutionary potential of Sars-CoV-2 to escape from these nAbs (2). However, instead of investigating the conditions that underlie this strong positive selection pressure, PHAs are doing their utmost to make people believe that mass vaccination will stop the transmission of these variants, lead to herd immunity and, therefore, put a stop to the Covid-19 pandemic. There is currently no single scientific argument or rationale to back any of these statements. On the contrary, numerous reports on breakthrough infections in vaccinees clearly illustrate that those who have not been immunized against Sars-CoV-2 are all but provided indirect protection by vaccinees (5, 14). The mantra that mass vaccination will at least contribute to controlling the pandemic is fully incoherent with the scientific knowledge gathered by molecular epidemiologists. Whereas phylogenetics-based natural selection analysis is a well-established method for studying evolutionary adaptation to enhanced host immune pressure, PHAs don’t seem to be impressed by data that are strongly suggestive of immune selection pressure resulting from human interventions targeting Sars-CoV-2 spike protein. Findings from this analysis indicate that as soon as a certain threshold of infectious pressure is reached, a sufficient number of subjects will harbor dominant mutants that could then spread across the entire population provided positive immune selection pressure is exerted by a substantial part of the population (1).


    Some VoCs have already been observed before mass vaccination campaigns were initiated. Because they reproduce more effectively in the population, these antigenically different variants are referred to as ‘more infectious variants’. In order to adapt to the increased pressure exerted by rising population immunity, variants are now increasingly incorporating additional mutations converging to specific sites within the receptor-binding domain (RBD) of the virus and conferring resistance to multiple S-directed Abs (1). The ongoing convergent evolution of immune escape mutations may come with a fitness cost of new variants for as long as the contribution of the population exerting selective immune pressure is not high enough to enable its enhanced propagation in the host population. It is important to note, though, that multiple distinct point mutations can each evade a multitude of neutralizing Abs (2). This would already explain why very few mutations (e.g., within the RBD) could already lead to full resistance to vaccinal Abs. At this stage of the pandemic, mutations in the S protein that impact neutralizing Abs are already present at significant frequencies in the global viral population, and evidence of expanding variants exhibiting a higher and higher level of resistance to vaccinal S-specific Abs is now accruing (3). In other words, it becomes increasingly obvious that Sars-CoV-2 immune escape variants are adapting to rising population immunity and improving on transmissibility by the stepwise acquisition of new mutations (as shown, for example, by the recent expansion of the delta ‘plus’ variant in several countries). All of the above already explains why the ‘success’ as proclaimed by the WHO and other health authorities or advising experts merely relates to short-term assessments of morbidity, hospitalization, and mortality rates. However, the data published by molecular/ genomic epidemiologists analyzing the ongoing adaptation of Sars-CoV-2 to the evolving immune selection forces at play in this pandemic of Sars-CoV-2 variants seem to indicate that the ‘success’ of current public health efforts will not last for much longer. This is because PHAs and their advising experts seem to ignore that mass vaccination campaigns conducted during a pandemic of variants fail to reduce the number of active infections to a level low enough to prevent natural selection of immune escape mutants (i.e., even including double or triple mutants!) and curtail their adaptation to a steadily rising population-level immune selection pressure, no matter the speed at which these campaigns are conducted. Their mantra that the acceleration of mass vaccination campaigns will prevent the virus from evolving variants that escape vaccine-induced immunity is, therefore, simply wrong. Since all of the current Covid-19 vaccines deployed in this mass vaccination program will contribute to raising immune selection pressure and eventually provide variants capable of evading S-specific Abs with a fitness advantage in the population (i.e., increasingly consisting of vaccinees!), neither herd immunity nor eradication could conceivably happen.


    In conclusion: There is no way that the ongoing pharmaceutical (mass vaccination) and nonpharmaceutical interventions will prevent the propagation of more infectious variants (those got already selected before the initiation of mass vaccination campaigns, presumably as a result of widespread implementation of stringent infection prevention measures) or variants comprising one or more RBD-associated nAb-resistant mutations. On the contrary, all evidence from molecular epidemiology indicates that the ongoing shift in natural selection forces exerted by the population on Sars-CoV-2 mutations is merely going to expedite the selection and propagation of more problematic variants of concern. It is beyond any doubt that growing vaccine coverage rates in the global population will further exploit the evolutionary capacity of Sars-CoV-2 to adapt to a higher and higher S-directed immune selection pressure until full vaccine resistance is achieved.


    There is now compelling evidence that sets of convergent mutations that have emerged in the context of VoCs evolved in response to the changing immune profile of the population. It has been postulated that convergent evolution of mutations primarily occurs in previously infected individuals or as a result of chronic infections (15-20). However, vaccinated people are far more prone to breeding viral immune escape variants than non-vaccinated naturally infected individuals. Why?

    In immunologically unprimed subjects, the peak of viral replication and shedding occurs well before host Ab responses appear. This already suggests that the host immune response in non-primed, S-sero-negative subjects (i.e., including previously asymptomatically infected subjects who lost their short-lived S-specific Abs) does not exert significant immune pressure on the virus. On the other hand, most countries started their vaccination campaigns before a substantial part of the population acquired immunity from natural infection. It is, therefore, reasonable to postulate that not natural infection or transmission but widespread deployment of vaccines is now becoming the primary cause of evolutionary selection pressure on viral expansion. This would already suggest that immune escape variants are now spreading rapidly in many parts of the world. It is fair to assume that the more widespread the presence of vaccinal S-specific Abs in the global population, the more the rate of evolutionary immune evasion from S-directed humoral immune pressure will rise. The frequent occurrence of suboptimal immune selection pressure exerted by virus-exposed vaccinees on Sars-CoV-2 spike protein will provide variants that are capable of evading S-specific vaccinal Abs with a selective transmission advantage. As already mentioned in previous contributions of mine, suboptimal S-directed immune pressure occurs in asymptomatically infected vaccinees who are still in the process of mounting Ab responses or possessing immature S-specific Abs (e.g., between 1st and 2nd injection of a 2-shot vaccine) or whose vaccinal Abs are low in titer and/ or not fully functional as a result of an immune-compromised health status.


    What determines the time required for Sars-CoV-2 to resist vaccinal Abs at a population level?

    It is fair to assume that RBD-targeted immune selection pressure exerted on a background of previously selected mutations enabling enhanced viral infectiousness will expedite natural selection of new, nAb-escaping mutations. Hence, circulation of more infectious viral variants is likely to expedite convergent evolution of additional mutations, including such that enable viral resistance to S-directed Ab-mediated immunity elicited by the vaccines.


    As a rule of thumb, the time for population-level anti-vaccine resistance to develop depends on


    The transmission or fitness advantage of the nAb-resistant variant (2). This factor is dependent on both, the magnitude of the population-level selection pressure and the intrinsic evolutionary fitness cost. The higher the relative percentage of individuals with nAbs to a given epitope (i.e., the more widely a given epitope is targeted) and the lower the intrinsic evolutionary fitness cost (i.e., the more effective the ‘infectious’ function of the mutated epitope), the higher the transmission advantage of the nAb-resistant variant and hence, the faster the mutated epitope will generate resistance to nAbs that are targeting it. In the case of vaccines, however, resistance will require a combination of multiple RBD-targeted mutations. This is what is currently causing in several countries an insidious period of pandemic quiescence as it takes more time for the virus to acquire a combination of multiple mutations to overcome vaccine-induced immunity despite widespread immune selection pressure (so-called ‘fitness valley-crossing time’; 2). Full resistance to the vaccines can only occur through intermediate steps wherein immune escape variants progressively evolve to incorporate additional mutations that are required to eventually reach full resistance to the vaccine. As long as the acquired subset of mutations does not suffice to escape the population-level immune pressure induced by the vaccine, the overall transmission or fitness cost from the immune escape mutations will be higher than the overall transmission or fitness advantage provided by the selection pressure exerted by the expanding prevalence of nAbs in the population.

    The mutation rate (2). This factor is dependent on both, the infectious viral pressure and the intrinsic mutability of the virus. The higher the mutation rate, the higher the likelihood that a combinatorial subset of mutations required for full-fledged resistance to the vaccine occurs. Viral variants may even harbor mutations outside of S protein that are subject to natural selection and thereby drive an enhanced mutation rate (21).

    Intermediate immune escape variants (i.e., harboring only a subset of the mutations required for nAb escape) are characterized by a lower fitness level. However, fast-speed mass vaccination campaigns that are rolled out on a background of a relatively high infectious pressure will mediate a relatively strong population-level immune selection pressure (as vaccine coverage rates rise quite rapidly). All of this will expedite the evolution of intermediate lower fitness variants into nAb-resistant variants (e.g., Chile case). Conversely, when a mass vaccination program is initiated on a background of low infectious pressure, the transmission of intermediate lower fitness variants will be low and more time will be required for nAb-resistant mutants to establish in the population (e.g., Israel case). This has been motivating certain ‘experts’ and policymakers to precipitate their conclusions on the success of mass vaccination campaigns in that they pretend that the pandemic is increasingly getting under control!


    It is fair to expect that the widespread presence of full-fledged, S-specific vaccinal Abs will eventually cause vaccine-resistant variants to dominate and further expand in the viral population. This is to say that ongoing mass vaccination campaigns will inevitably entail full resistance of Sars-CoV-2 to all S-targeting Covid-19 vaccines and are, therefore, highly likely to lead to an impressive wave of infection and disease in vaccinees, especially in those who have not previously experienced Covid-19 disease.


    It suffices to acknowledge that the ongoing convergent evolution of new variants is driven by natural selection pressure to conclude that mass vaccination campaigns conducted in the heat of a pandemic are now promoting the expansion of immune escape variants that vaccines will eventually no longer be capable of protecting against.

    Whereas global and stringent infection containment measures may eventually have led to the population-level selection of more infectious variants, increasing vaccine coverage rates are now likely to promote population-level selection of nAb-evading viral mutants. Viral VoCs that spontaneously arise as a result of viral replication cannot all of a sudden start to outcompete lineages that circulate in several different countries unless they acquire a competitive advantage. They can only acquire such an advantage if the environmental conditions they are exposed to change in ways that provide them with a transmission advantage when compared to the wild-type virus or previously circulating strains/ variants. Because some mutations will endow the virus with enhanced intrinsic viral infectiousness, viral variants comprising such mutations will naturally be selected when altered conditions in the host environment exert pressure on viral infectiousness. In this way, viral propagation and survival can be secured. Provided the selection pressure on viral infectiousness is widespread in the population, more infectious variants will rapidly gain a fitness advantage and quickly expand in the population. The dominance of such new viral variants is, therefore, indicative of the natural selection of a virus that is more transmissible at a population level. However, the more the combination of mutations required for immune escape impacts viral fitness, the more time it will take immune escape variants to reach a high enough infectious pressure in the population or the more immune selection pressure will need to be exerted by the host environment to compensate for the incurred evolutionary fitness cost (see above). Along the same lines of reasoning, it is fair to conclude that more infectious or nAb-resistant variants will expand in prevalence upon their introduction into countries where mass vaccination is already well advanced. These variants are, indeed, well adapted to the widespread immune selection pressure that has been generated in the population as a result of mass vaccination. Thanks to an excellent breeding ground, these variants will now reproduce more effectively than the previously circulating strains.


    It is fair to postulate that the more widespread the presence of full-fledged, S-specific vaccinal Abs, the more readily variants will adapt to the immune environment they are exposed to and eventually evolve resistance to the vaccines as they spread in the host population. This is to conclude that ongoing mass vaccination campaigns will inevitably entail full resistance of Sars-CoV-2 to all S-targeting Covid-19 vaccines. This is highly likely to rapidly provoke a resurgence of Sars-CoV-2 infection and disease, especially in vaccinees. As already mentioned above, cases of severe disease would be expected to be more frequent among vaccinees who did not previously contract Covid-19 disease.


    How can human behavior or infection prevention measures promote the propagation of mutations in Sars-CoV-2 spike protein?

    The natural host environment of Sars-CoV-2 can create several barriers that impact viral transmissibility and survival. Enactment of infection prevention measures or overcrowding are examples of situations threatening viral spread. As the infectiousness of Sars-CoV-2 is strongly shaped by the physicochemical properties of its spike protein, the above-mentioned obstacles will exert selection pressure on the binding affinity of Sars-CoV-2 S protein and, therefore, contribute to the natural selection of mutations that enable stronger binding of S protein to the Ace-2 receptor of permissive cells. To adapt to such environmental constraints, viral variants have been shown to independently evolve to acquire multiple unique as well as convergent mutations (1). Convergent evolution of mutations comprised within S-associated, immunologically relevant genes are proof of natural selection and illustrate the evolutionary capacity of Sars-CoV-2 to adapt to S-targeted selection pressure.


    Renowned experts in molecular epidemiology are now increasingly finding that the emergence and ongoing convergent evolution of Sars-CoV-2 variants coincide with a major global shift in the Sars-CoV-2 selective landscape (1). As this ongoing shift also coincides with globally conducted mass vaccination campaigns, the question arises as to whether these ongoing campaigns have the potential to foster convergence between evolving variants. This boils down to the following question:


    Does mass vaccination with current Covid-19 vaccines enable populations to exert S-directed immune selection pressure?

    This is, indeed, an important question: If mass vaccination enables the vaccinated population to exert S-directed immune selection pressure, the likelihood that current Covid-19 vaccines will be able to control the pandemic should be seriously questioned for adaptive evolution of Sars-CoV-2 variants has already been shown to coincide with epidemic surges in multiple parts of the world. As already mentioned, most – if not all – of the above-mentioned evidence directly emerges from in-depth research conducted by internationally recognized molecular epidemiologists. These researchers acknowledge that rising population immunity and public health measures may complicate the control of the pandemic by virtue of their positive selection effect on immune escape variants (1). However, they do not advance any hypothesis as to the underlying causes of rising immunity that leads to a transmission advantage for S-directed immune escape mutants other than through individuals who are chronically ill and sustain prolonged viral replication as a result of insufficient immune control. This is probably an area where molecular epidemiologists should synergize with immunologists to understand, for example, that during a pandemic, previously asymptomatically infected subjects may become re-infected at a point in time where their innate CoV-nonspecific Abs are still suppressed by suboptimal S-specific Abs (which they acquired as a result from that previous asymptomatic infection). More importantly, molecular epidemiologists may find it useful to learn from vaccinologists as a better understanding of the immune priming by vaccines, as compared to natural infection, could inform a more targeted surveillance of viral mutations and variants. In this regard, it is important for them to understand that mass vaccination in the heat of a pandemic, much more than natural infection of immune-suppressed subjects, provides a panoply of conditions for individuals to become infected while only harboring suboptimal, S-specific Abs. Suboptimal stimulation of S-specific Abs could be due to individual insufficiencies in immunological responsiveness to the vaccine but inevitably occurs in all vaccinees for as long as they are in the process of mounting their Ab response. This is particularly problematic in vaccinees who have not yet received the second shot of a 2-dose Covid-19 vaccine. In these vaccinees, the S-specific Ab response after the 1st dose will not suffice to control replication and transmission of more infectious viral variants. In addition, exposure of vaccinees to antigenically different variants is also to be considered a case of suboptimal S-specific Abs and would already explain why increasingly problematic variants (e.g., VoCs or other problematic immune escape variants with deletions in the N-terminal domain of S protein) are overrepresented in vaccine breakthrough infections (5, 14). All of the above situations will enable a growing part of the population (vaccinees!) to exert selective immune pressure on the S protein when exposed to Sars-CoV-2 (which is all but a rare event during a pandemic!). Unfortunately, vaccinees are not systematically monitored for the shedding of antigenic Sars-CoV-2 variants and hence, the information on the type of variants they shed is scarce, the effective reproduction number underestimated, and the evolutionary potential of the virus to evade S-specific Ab underexplored. As a result, reports on the relative distribution of variants are likely skewed to less problematic variants as those may still have a fitness advantage in vulnerable people compared to variants comprising a combination of nAb-resistant mutations.


    As some sources of population-level selective pressure are known to be amenable to human intervention, there is an urgent need for systematic genomic sequencing of circulating variants in vaccinees as this would provide us with unambiguous clarification as to whether or not mass vaccination campaigns enable a population to exert immune-mediated selective pressure on critical functional characteristics of Sars-CoV-2 such as virulence, transmissibility, and nAb-resistance.


    Why will mass vaccination campaigns conducted in the midst of this pandemic inevitably cause viral immune escape at the population level, irrespective of the speed at which these campaigns are progressing?

    It has been established that the threshold number of individuals required for natural selection is far lower than the threshold number for neutral genetic drift to drive evolutionary changes in the Sars-CoV-2 landscape (2). But also mathematical modeling has already shown that prophylactic nAb treatment (including vaccination) of a relatively low percentage of the population already suffices to provide an immune escape mutant impacting the neutralizing Ab capacity with a significant transmission advantage compared to the wild virus (2). In addition, people enrolled in mass vaccination campaigns conducted during a pandemic are often exposed to an environment of relatively high infectious pressure. This will increase the likelihood for vaccinees to harbor a dominant double or even triple mutant that is capable of evading a multitude of nAbs and hence, likely to serve as a source for population-level resistance of Sars-CoV-2 to Covid-19 vaccines.


    From a scientific perspective, it is impossible to imagine that the ongoing large-scale vaccination campaigns are not going to rapidly and globally breed vaccine-resistant mutants instead of generating vaccine-mediated herd immunity. As of early March 2021, I have, therefore, been warning several times against the rapid resurgence of Sars-CoV-2 morbidity and mortality rates that this evolution is now highly likely to cause, especially in vaccinees. Hence, I repeatedly called upon PHAs worldwide to immediately stop all mass vaccination campaigns. Back in 2004, scientists have already published that substantial viral replication (i.e., substantial infectious pressure) combined with substantial immune selection favors the transmission of immunologically selected viral variants (26).


    Will the consequences of viral resistance to Covid-19 vaccines also affect non-vaccinated individuals?

    Resistance to Covid-19 vaccines will only raise the infectious pressure and thereby increase the likelihood for non-vaccinated subjects to contract Covid-19 disease. On the other hand, nonfunctional vaccinal Abs in vaccinees could lead to Ab-dependent enhancement (ADE) of Covid-19 disease (2, 25). ADE is likely to shorten the pre-symptomatic phase of Covid-19 disease, viral shedding could be more easily and rapidly contained. Timely containment of viral transmission would contribute to diminishing exposure of non-vaccinated individuals to high infectious pressure. Provided unhampered functionality of their CoV-nonspecific innate Abs, diminished infectious pressure would likely protect non-vaccinated individuals from contracting Covid-19 disease. It is uncertain whether non-vaccinated individuals who acquired S-specific nAbs as a result of natural infection could become susceptible to ADE when exposed to vaccine-resistant Sars-CoV-2. The risk may exist for as long as the concentration of these nAbs in their blood is high enough to outcompete innate, CoV-nonspecific Abs at the portal of viral entry. It is likely, though, that both, vaccinated and non-vaccinated subjects who previously contracted Covid-19 disease will be better protected against severe disease upon re-exposure thanks to priming of protective, cytotoxic T cells.


    Vaccine-elicited S-specific T cell responses against variants are largely preserved and have been suggested to enable robust vaccine efficacy against variants when the neutralizing capacity of vaccine-elicited Abs may not provide sufficient protection (11). Could vaccine-induced T cell immunity, therefore, diminish the prevalence of viral variants and mitigate the resurgence of morbidity and mortality waves?

    Some publications suggest that increased breadth in S-specific vaccinal T cell responses in vaccinated as compared to non-vaccinated individuals may compensate for insufficient neutralization capacity of S-specific vaccinal Abs against a number of new, more infectious variants. This would, therefore, still enable vaccines to provide robust protective vaccine efficacy against emerging variants. It is unlikely, though, that largely preserved T cell responses against variants mediate S-specific killing of virus-infected cells. This is because killing by cytolytic CD8+ T cells (CTLs) is known to be genetically determined by protective MHC class I alleles. No evidence of promiscuous or universal, Sars-CoV-2 S-derived CTL epitopes has been reported. The robustness of protective vaccine efficacy against variants across a genetically heterogeneous host population can, therefore, not be explained by CTL-mediated killing as the latter would be MHC class I-restricted, even if S-derived CD8+ T cell epitopes are conserved. Robustness of protective vaccine efficacy against multiple variants is most likely due to innate, cytokine-mediated immune cascades that are largely triggered by polyfunctional, broadly preserved memory T cells. These cytokine-mediated responses likely synergize with nAbs to further reduce viral load (and hence, likely diminish the likelihood of [severe] disease) but fail to abrogate viral transmission or curtail the expansion of viral variants. This is because non-antigen(Ag)-specific innate immune responses cannot target and eliminate Sars-CoV-2-infected cells. It is reasonable to assume, however, that vaccine-elicited S-specific T cell responses will contribute to promoting viral evasion from innate immune mechanisms when elicited in the context of large-scale vaccination campaigns during a pandemic. Innate immune evasion mechanisms are well known and have been extensively described (12, 13). This would ultimately result in a universal (i.e., MHC-unrestricted) and nonAg-specific decline in vaccine efficacy towards all infectious Sars-CoV-2 variants.


    Why are mass vaccination campaigns likely to increase Covid-19 morbidity and mortality rates?

    From a purely scientific perspective and even regardless of all (important!) ethical issues they raise, mass vaccination campaigns conducted in the midst of a pandemic are doomed to fail and have unforeseeable health consequences, not only for individual vaccinees but also for the global human population.


    As already mentioned, changes in the ‘traditional’ host environment (e.g., implementation of stringent public health measures and social distancing; overcrowding) may alter the evolutionary dynamics of the pandemic and drive natural selection and dominant propagation of more infectious variants (or, alternatively, promote their rapid expansion once they become de novo introduced into a population). Likewise, it is reasonable to assume that large-scale vaccination campaigns conducted during a pandemic will drive natural selection and dominant propagation of nAb-evasive variants. However, as viral adaptation evolves, replication and transmission of such naturally selected immune escape variants by asymptomatically infected or mildly ill vaccinees will become more and more frequent and eventually increase the risk of rapid re-exposure for non-vaccinated, previously asymptomatically infected individuals. This is now likely to prompt a new wave of morbidity and mortality in the non-vaccinated part of the population. In countries where mass vaccination campaigns are rolled out on a background of low infectious pressure, it will take more time for rising vaccine coverage rates to drive convergent evolution of additional, naturally selected mutations such as to ensure viral persistence in the face of a stronger and more widespread vaccine-induced immune response. However, there shall be no doubt that the endgame of this convergent evolution of vaccine-mediated immune escape mutants is full resistance of Sars-CoV-2 to the Covid-19 vaccines. When this happens, vaccinees, in particular, will become extremely vulnerable to Covid-19 disease as they will no longer be able to rely on their innate Abs for those will be outcompeted by their vaccinal Abs for binding to S protein.


    It is important to note that it suffices for the virus to escape S- or RBD-directed immune pressure in order to become more infectious or to resist protective (neutralizing) vaccinal Abs, respectively. As neither previously asymptomatically infected, non-vaccinated individuals nor previously immunologically naïve vaccinees have experienced protective T cell priming, immune evasion from S-specific Abs is sufficient for Sars-CoV-2 to cause Covid-19 disease in these people. Given the intensity of natural selection signals observed in the current genomic landscape of Sars-CoV-2 spike protein (1), it is reasonable to assume that a further rise in population-level immune selection pressure on this protein (i.e., as a result of continued mass vaccination campaigns) will ultimately provide variants capable of evading a full set of vaccinal Abs (including those raised by 2nd generation vaccines) with a transmission advantage. As already mentioned, this is expected to dramatically raise morbidity and mortality rates in vaccinees.


    Why are most countries not yet affected by enhanced circulation of increasingly immune-resistant variants despite an advanced stage of their mass vaccination campaigns?

    Full-fledged vaccine resistance is not yet observed as it may take much longer for a combination of multiple synergizing immune escape mutations to occur in a sufficient number of individuals in the population. However, once these immune escape variants are present in sufficient frequency, they will establish rapidly in populations that are subject to mass vaccination (due to widespread S-directed immune selection pressure). It is, however, important to note that during this period of pandemic quiescence, vaccination may lead to an increased risk of ADE as S protein from intermediate variants, which possess only a subset of the S-associated mutations required for full resistance to the vaccine, may still be recognized (but not neutralized) by vaccinal Abs (see above).


    Will mass vaccinations have a different outcome depending on geographic and/ or demographic factors?

    Regardless of the current evolutionary dynamics of the pandemic in any given country, immune escape variants will ultimately converge to a common adaptive endpoint, which is full resistance to S-directed nAbs induced by Covid-19 vaccines or resulting from natural infection. The speed at which Sars-CoV-2 is expected to develop resistance to S-specific nAbs induced by the current vaccines or acquired following natural infection will – among other, above-mentioned factors – depend on the speed at which mass vaccination campaigns are conducted. Enrolling youngsters and children in these mass vaccination campaigns is only going to rapidly expand the breeding ground for nAb-resistant variants and expedite the evolution depicted above.


    Why are follow-up vaccines using key nAb epitopes from variant-associated spike protein unlikely to solve the issue of immune escape variants?

    First, spike RBD displays a high level of evolutionary versatility whereas Covid-19 vaccines only induce a relatively narrow immune response (i.e., directed at a few immunodominant domains within a single viral protein). It is, therefore, reasonable to assume that the evolutionary capacity of Sars-CoV-2 to evolve variants capable of evading multiple nAbs reaches far beyond the breadth of S-associated epitopes Covid-19 vaccines can possibly target (2, 3, 9). This already suggests that these vaccines are highly likely to drive mutation-mediated escape from S-specific host Abs.


    Upon re-vaccination with updated S-targeting vaccines (so-called ‘second generation’ vaccines), previously vaccinated people will rapidly recall their original vaccinal Abs while those who are waiting for their updated vaccine shot may do so as a result of natural exposure (as the virus will, indeed, still be circulating, primarily among asymptomatically infected vaccinees). In immunology, this phenomenon is known as ‘antigenic sin’. Consequently, a high level of S-directed immune selection pressure will be maintained within the vaccinated population, thereby promoting the further expansion of viral variants and accelerating the speed at which variants will evolve a repertoire of additional immune escape mutations that is sufficient to eventually enable full resistance to the updated vaccine as well. In this context, it is also important to note that one single additional mutation could suffice to abolish the enhanced neutralization capacity of the updated vaccine by virtue of epistatic interaction between the additional mutation and multiple previously established adaptive mutations targeted by vaccinal nAbs. In addition, molecular epidemiologists are increasingly worried about a potential expansion of recombination-generated combinations of immune escape mutations as those could occur during co-infections with different variants and generate even more problematic variants of concern that will better match the evolving fitness landscape of the continuing pandemic (1, 9).


    When high infectious pressure coincides with high immune selection pressure, partially resistant variants can be expected to transit more rapidly through the ’valley of lower fitness’ and hence, expedite the emergence of dominant variants that fully resist the updated vaccines. This is to say that steadily increasing vaccine coverage rates combined with relaxed infection prevention measures and global expansion in the prevalence of more infectious variants are now serving as a breeding ground for upcoming nAb-resistant variants.


    Re-vaccination with second-generation vaccines is all but comparable with seasonal updates of Influenza vaccines as the latter are administered on a background of herd immunity. Dedicated molecular epidemiologists seem to recognize the likelihood that updated S-based Covid-19 vaccines may fail and state that “Further studies may be required to understand the risk immune evasion poses to a strategy of annually updated vaccines” (2).


    Could an immediate and global halt of mass vaccination campaigns still prevent the emergence of more harmful viral recombinations or resistance of Sars-CoV-2 to Covid-19 vaccines?

    A global and immediate halt of mass vaccination campaigns would allow to diminish immune selective pressure exerted on sites within the S protein that mediate nAb evasion. However, at this fairly advanced stage of the global mass vaccination program, it is probably already too late to prevent viral resistance to S-Abs, even if mass vaccination campaigns would immediately and globally be halted, and even though vaccine coverage rates are still fairly low in a number of low-income countries. This is because


    nAb-resistant virus selected in a particular population will easily adapt and expand upon their introduction into other populations that are undergoing a similar shift in the Sars-CoV-2 fitness landscape, even though the local variants they are harboring are less advanced in their adaptive process of evolutionary convergence of immune escape mutations

    the current spectrum of escape mutations already lays the groundwork for multiple recombinations to occur as viral spread continues. Combinations of immune escape mutations more readily enable variants to circumvent vaccine-induced immunity or acquire other phenotypic characteristics that could potentially be more harmful (1, 2, 3, 9). Some of these combinatorial variants could, therefore, be more problematic than those which circulated before.

    Consequently, it is reasonable to assume that an immediate halt of all Covid-19 vaccination campaigns could at most delay full resistance of Sars-CoV-2 to the vaccines by a few months. However, recombinations are likely to lead to super variants with unpredictable phenotypic characteristics, some of which may be responsible for a further increase in viral infectiousness and/ or virulence or could even enable adaptation to another mammalian species (7). As already mentioned, recombinations are promoted by co-infection with different variants. At this stage of the pandemic, co-infection with different variants becomes increasingly likely as infection prevention measures are now being relaxed in many countries (9). Adaptation to other mammalian species may result from enhanced binding affinity of mutated spike protein for their Ace-2 receptor (e.g., in case of the Sars-CoV-2 Y453F mink variant) and generate an additional asymptomatic reservoir for recurrent transmission to humans (4).


    Unless aggressive multidrug treatment is implemented at an early stage of disease and large-scale chemoprophylaxis campaigns are conducted, resistance of Sars-CoV-2 to Covid-19 vaccines is, most certainly, going to provoke a steep incline of morbidity and mortality rates in vaccinees, especially in those who did not contract Covid-19 disease prior to vaccination.


    Are scientists suspicious of mass vaccination enhancing expansion of vaccine-resistant Sars-CoV-2?

    In this regard, it suffices to cite D. Van Egeren et al. (2):


    “Evidence from multiple experimental studies showing that single RBD point mutations can lead to resistance to neutralizing convalescent plasma from multiple donors suggests that specific single mutants may be able to evade spike-targeting vaccinal immunity in many individuals and rapidly lead to spread of vaccine-resistant SARS-CoV-2. One variant that can escape convalescent plasma neutralization is already circulating in South Africa and could experience greater positive selection pressure once vaccines are deployed widely”. These authors further suggest that natural selection of multiple mutations in individuals possessing nAbs against Sars-CoV-2 spike protein “could accelerate the emergence of vaccine-resistant strains in the months following vaccine deployment” and state that “Further studies are required to understand the risk immune evasion poses to a strategy of annually updated vaccines”. Additional citations from scientists studying the evolutionary biology of Sars-CoV-2 go as follows:

    “… vaccines themselves represent a selection pressure for evolution of vaccine-resistant variants…” (9).


    The notion that vaccines have the capacity to drive immune evasion of mutable pathogens and enable dominance of antigenically different variants with altered biological characteristics when deployed at population scale is certainly not new (8, 13, 22). This knowledge combined with the remarkable ability of Sars-CoV-2 to rapidly adapt to new environments and different hosts, in particular via convergent evolution of specific spike mutations (7, 23, 24), led at least some scientists to state that “With increasing levels of host immunity helped by the deployment of vaccines and ongoing widespread SARS-CoV-2 circulation, we fully expect to see increased evidence for adaptive evolution in Spike and other genes…” (7) or that “Mutations affecting the antigenic phenotype of SARS-CoV-2 will enable variants to circumvent immunity conferred by natural infection or vaccination” (3). Other scientists come to the following conclusions: “Subsequently, many other changes in the spike protein were found to propagate rapidly, showing that the bulk of the selection pressure on this protein comes from adaptation to the host. We can therefore anticipate that this protein, and to a lesser extent the nucleocapsid protein, will evolve most rapidly under the selection pressure of vaccination” (9) or: “However, there is growing evidence that mutations that change the antigenic phenotype of SARS-CoV-2 are circulating and affect immune recognition to a degree that requires immediate attention”. But scientists also acknowledge that a recombination event within Sars-CoV-2 variants or between a Sars-CoV-2 variant and Sars-CoV-2 from bats could be highly problematic in terms of precipitating resistance to the vaccines: “Due to the high diversity and generalist nature of these Sarbecoviruses, a future spillover, potentially coupled with a recombination event with SARS-CoV-2, is possible, and such a ‘SARS-CoV-3’ emergence could be sufficiently divergent to evade either natural or vaccine-acquired immunity, as demonstrated for SARS-CoV-1 versus SARS-CoV-2. We must therefore dramatically ramp up surveillance for Sarbecoviruses at the human–animal interface and monitor carefully for future SARS-CoV emergence in the human population” (7).


    Biologists studying the genomic composition of CoVs in general and that of CoV-2 in particular published convincing evidence that also innate, nonAg-specific antiviral immune responses exhibited by infected host tissues (i.e., not only including lymphoid tissue!) exert immune selection pressure that shapes the genomic composition of infecting CoVs (10). As already mentioned above, vaccine-mediated T cell immunity is thought to contribute to protection by virtue of the innate immune cascades they stimulate.


    It is generally agreed amongst molecular epidemiologists that resistance to nAbs and hence, to vaccine-induced immunity, could considerably be delayed by reducing the number of active infections (i.e., infectious pressure) in ways that do not exert a specific selective pressure on the virus. They literally state: “In this context, vaccines that do not provide sterilizing immunity (and therefore continue to permit transmission) will lead to the buildup of large standing populations of virus, greatly increasing the risk of immune escape”(2).


    It is almost impossible to believe that scientists studying the genomic/ molecular epidemiology or evolutionary biology of Sars-CoV-2 would not understand that mass vaccination campaigns promote natural selection and propagation of immune escape variants when they all come to the conclusion that selective immune pressures exerted by antiviral host immune responses provide fitness-enhancing mutations with a transmission advantage enabling their adaptation to the infected host (tissue)-specific environment. In light of all scientific evidence provided and the sinister perspective of the current evolution when put in an immunological and vaccine context, knowledgeable scientists should feel a moral and ethical obligation to loudly voice their concerns publicly. Compassionate scientists who have been taking a deep dive in these complex matters are now increasingly left with the impression that health authorities and advising experts will simply continue to deny that they are desperately wrong, no matter how compelling the scientific evidence that has been brought to the table and no matter the consequences this unprecedented public health experiment may involve for many years to come

    Summary

    SARS-CoV-2 Lambda, a new variant of interest, is now spreading in some South American countries; however, its virological features and evolutionary trait remain unknown. Here we reveal that the spike protein of the Lambda variant is more infectious and it is attributed to the T76I and L452Q mutations. The RSYLTPGD246-253N mutation, a unique 7-amino-acid deletion mutation in the N-terminal domain of the Lambda spike protein, is responsible for evasion from neutralizing antibodies. Since the Lambda variant has dominantly spread according to the increasing frequency of the isolates harboring the RSYLTPGD246-253N mutation, our data suggest that the insertion of the RSYLTPGD246-253N mutation is closely associated with the massive infection spread of the Lambda variant in South America.


    Highlights


    Lambda S is highly infectious and T76I and L452Q are responsible for this property


    Lambda S is more susceptible to an infection-enhancing antibody


    RSYLTPGD246-253N, L452Q and F490S confer resistance to antiviral immunity
