The Israelis did a study of 2.5 million workers for their health system that received the vaccine. I think Pfizer and Moderna. The number that wound up being diagnosed with myocarditis or pericarditis was a little more than 1 in 50,000.

Studies I've seen of the incidence of myocarditis in people diagnosed with covid itself is around 1 in 800. So if you have ever had covid your odds of having had myocarditis is about 70 times greater than if you simply got the vax.

In the case of both vaccinated and actual covid cases the incidences are probably higher for the reasons Dr Campbell mentioned.

Of course there is increasing evidence a covid infection can cause a host of other long term problems. It seems to attack the brain in particular. We might not know the long term impact of this until years down the road with post mortem studies kind of like with CTE.

The point is that covid itself is nasty, so you pick your poison when it comes to getting vaxxed or not.
