This made more sense to me when people still believed that the shots meant getting covid was very unlikely. It's easy to find people who got lots of shots, it's hard to find people who didn't get covid.
It always seemed implied that p(shot cardio issues) < p(covid cardio issues), and nobody ever talks about p(shot cardio issues) + p(covid cardio issues).
Did anybody rigorously demonstrate that a vaccinated covid case doesn't have these risks?
