Here's the weekly Ontario report on vaccine side effects: at the end is the myocarditis/pericarditis breakdown:
https://www.publichealthontario.ca/en/health-topics/immuniza...
> In adjusted analyses, patients with COVID-19 had, on average, 15.7 (95% CI = 14.1–17.2) times the risk for myocarditis compared with patients without COVID-19;
Okay, so it's 'just' an order of magnitude higher. Unfortunately, myocarditis is one of the least serious side effects of COVID.
If you have a choice between a vaccine that offers 95% protection against COVID, and a 1 in 5000 chance of myocarditis, and one that offers 90% protection against COVID, and a zero chance of myocarditis, you're better off taking the former. You're also far better off taking either one, compared to being unvaccinated.
Now you've already been caught making false claims once, the decent thing to do would be to stop being so cocksure and apologize, not dig in.
