But with large sample sizes like the entire population you're guaranteed to get negative health incidents (which happen all the time) shortly after receiving a vaccine that are unrelated.
Add in the fact that many people that fall into this category are going to talk and find each other and be vocal it's not hard to see why some arrive at conclusions that aren't supported by the data.

Yeah, about 1 in 225 people in one of the Pfizer trials had a severe adverse reaction in the first couple of months after being vaccinated. I'm sure if people wanted to, they could try to find all kinds of ways to argue a link between those reactions and being vaccinated. And why not? They got vaccinated and within a matter of weeks they had a newly diagnosed severe condition (cardiovascular issues, cancer, immune system disorders, etc.). It must be related to getting vaccinated. Except for the fact that that was the severe adverse reaction rate in the placebo arm.
