> We estimated extra myocarditis events to be between 1 and 10 per million persons in the month following vaccination, which was substantially lower than the 40 extra events per million persons observed following SARS-CoV-2 infection.
> Whilst myocarditis can be life-threatening, most vaccine-associated myocarditis events have been mild and self-limiting. The risk observed here is small and confined to the 7-day period following vaccination, whereas the lifetime risk of morbidity and mortality following SARS-CoV-2 infection is substantial.
"Subgroup analyses by age showed that the increased risk of events associated with the two mRNA vaccines was present only in those aged under 40 years."

I'm not sure how it compares to the effects of covid itself, just something to think about / read up on to make an informed decision.
