I used to never get hives, and then I started getting hives out of the blue, years before covid was ever a thing. This is just a thing that happens to some people - look up "chronic idiopathic urticaria". 20 percent of the population, on quick google. I'm saying that the hives may have been caused by the covid booster, maybe not, you need actual aggregate statistics on the population to make any causal claims.
