Anecdotally, I have yet to hear of an unvaccinated person getting Covid more than once. Two vaccinated friends in their 50s have died - one from a heart failure, the other from a brain tumor... both very unexpected.Now do a comparison to those who get COVID with vs those who get it without vaccine.
Myocarditis risk is higher amongst the unvaccinated, and you're going to get the virus regardless. Pick your poison.
