I talked to a Intensivist in Michigan. He didnt say much about HCQ but did say something about "Trump thinks he's a doctor and a engineer" -- but what was notable that he said "everyone is going to get this disease, and anyone who thinks vaccine has no idea....most vaccines are at most 15% effective"

"In industrialised countries, several infectious diseases have been controlled and, in some cases, eliminated through routine vaccination. The generally high level of vaccination coverage has led to a dramatic decline in the reported incidence of many vaccine-preventable infectious diseases (Fig. 1) (7). A comparison between the period prior to the implementation of national vaccination recommendations in the United States and 2006 showed a greater than 99% decline in the number of cases of diphtheria (100%), measles (99.9%), paralytic poliomyelitis (100%), and rubella (99.9%). A greater than 92% decline in cases and a 99% or greater decline in deaths were shown for mumps, pertussis, and tetanus (8, 9). In 2013, it was estimated that 103 million cases of childhood disease in the United States had been prevented by the use of vaccines since 1924, of which 26 million cases in the past decade alone (10). A similar trend has been observed in Europe (Table 1) (9, 11). In France, diphtheria, tetanus and polio, BCG (tuberculosis), and pertussis vaccines were estimated to be responsible for saving more than 400,000 years of life (4)."
BTW, for smallpox: 100% eradicated by vaccine. Polio would be also except for the abject morons who misrepresent the risks so that some people won't use it. Note that "common" influenza vaccine is 67% effective in preventing influenza A (H1N1) which is a pandemic strain which in the past killed millions and caused the 1918 world wide disastrous pandemic. Now, it's mostly prevented by herd immunity conferred by mass vaccination. And if someone gets it, it can be treated effectively with antiviral meds.
and ... in the specific case of influenza: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5815489/
"VE was estimated to be 25% (CI = 13% to 36%) against illness caused by influenza A(H3N2) virus, 67% (CI = 54%–76%) against A(H1N1)pdm09 viruses, and 42% (CI = 25%–56%) against influenza B viruses. ... "
But beyond that, when vaccinated individuals do get sick with the illness, they are less sick and recover faster and there are fewer deaths and hospitalizations.
Obviously, vaccines vary. What the efficiency (VE) will be for a coronavirus vaccine is yet to be determined. And even if a vaccine to confer useful lasting immunity is impossible or takes a very long time, related research into natural and synthetic (monoclonal) antibodies may result in an effective treatment even before a vaccine and from a related technology.
I will defer insulting the surprisingly consistent (consistently wrong) poster, though it is very tempting, out of concern for moderators. However there should be an award for those are most wrong most of the time. Maybe a contest. And a Pigasus award perhaps. With an invitation to submit a paper to the Journal of Irreproducible Results.
