Does eating one poisonous berry make all berries bad? If someone eats a poisonous berry is the only intelligent conclusion that all berries are bad and should be avoided. Is the only rational decision after eating a poisonous berry to become "anti-berry"?

These people were exposed to one vaccine that had a blatant negative effect. The logic here is perfectly sound. All the other stuff they've been exposed to regarding vaccines has been that they usually cause minor to no issues and actually work to prevent the illness. Whether that's true or not is beside the point, that is what they know and they're not going to conclude that all of that is fake just because the Rona shot is blatantly no good. Doing so is what would actually be idiotic. The rational conclusion, especially in normie-land where all the different vaccines are separate products made by a bunch of separate companies rather than an all-encompassing evil cabal that controls them all, is that the Rona shot itself turned out no good and gave them an adverse reaction that they were not properly informed about, on top of the shot not working. As far as most normies know, none of those things are true or concerns regarding other vaccines, so why conclude they're all bad and not just that the one that had the issues is bad?
