I didn't downvote, but I'll answer anyway: there was a propaganda campaign of unprecedented scale espousing the "safety" of these covid vaccines (which didn't go through the normal, rigorous testing process that vaccines usually go through). The propaganda was so successful that a large percentage of the population is still fanatically making false claims about vaccine safety, despite the large number of people who reported serious adverse side effects. At this point pretty much every person on earth knows at least one person who has "long covid symptoms" from the covid vaccine. And yet we have a bunch of people re-enacting the propaganda of 2021 and downvoting any comment that talks about vaccine side effects...
Most of them seem to be convinced it was because of finally getting infected (just scroll around this page for a bunch of examples), and I think they're half right. Late 2022 there was a paper about how the mRNA vaccines caused the body to produce more IgG4 antibodies*, which, simplified, are a sort of "stand down" antibody meant for things like dust and pollen.
I think in at least some people the mRNA vaccines appear to work by suppressing symptoms (which also explains Pfizer's 95% effective, in that trial they only tested people who actually showed symptoms first), but actually they allow the virus to run rampant when the person is eventually infected. So the association is with the virus instead of the vaccines, and they assume it would have been worse without when we just really don't know.
I have a family member who got severe symptoms after each vaccine shot. For the first 3 shots the symptoms eventually subsided. For the 4th shot they didn't. And it's been a few years now. I suspect it's a chronic condition.
Coming back to your point, is it possible that my family member - just by pure coincidence - happened to get covid immediately after each shot? 4 times?
