So vaccination (can) produces the same symptoms as long Covid.
Big Pharma mafia:: Vaccines can help to cure long Covid. Any more questions?
Yes, many more. In fact as I said above long COVID is badly defined, not well studied. Can vaccines have side effects because of adverse immune reponse? Sure. Does COVID generate side effects due to adverse immune response? Sure. The key question is where is the cross-over, where risk of COVID gets to be smaller than risk of vaccines.
That is going to be an open scientiific question for quite some time. Those interested in it will not leap on evidence in one direction, but look at all evidence dispassionately.
It is, alas, also a pressing political question. Publicising low incidence problems in vaccines leads to vaccine hesitancy which is bad for those who hesitate (they get COVID, and suffer) and bad for society (COVID rates are higher overall).
Regulators have a responsibility to ensure that emergency use vaccines are only made available to those people who do not personally suffer more risk from the vaccine than from the virus.
For emergency use, with COVID, we can be sure:
The science will be uncertain, and change over time
The pressure to allow more vaccination, for the good of all, is high in many countries.
I have no reason to think the regulators who make these decisions in different countries are caving in to that pressure. But I'm glad i don't have to make that judgement. You can maybe get some insight by comparing different regulators but politics can push scientists towards different judgements in both directions. Doctors are as capable of infection with extreme-right (or extreme-left) memes as anyone.
