The anti vaxxers are the masters of anecdotal evidence. There was a woman who died after her 2nd dose of the vaccine and they immediately jumped on it as proof that the vaccine was worse than the disease.
Turns out she overdosed on Tylenol to treat the side effects of the vaccine which led to liver failure and then renal failure and then death.
But they refuse to accept that and claim its a "coverup". Like the US Government is even capable of maintaining such a conspiracy.
