I got the vaccine long before getting Covid (about a year before), and have had palpitations ("butterflies") since the vaccine.
Are the two related? No idea. But it illustrates the fallacy of relying on anecdote. For anything.
That said: we know that the vaccine causes myocarditis in younger men, and the rate is at least in 1 in 5000, and quite probably higher than that [1]. A recent study of Thai boys suggested a much higher rate, on the order of 1 in 100 [2]:
just a reminded because some people don’t know, not advocating for an additional original strain booster or any cause aside from that it definitely needs to be factored into incidence reports
I think your link (or rather the reference in your link) refutes your statement. If I'm reading correctly, beyond age, you also have to subgroup by sex and by the particular vaccine type to find a subgroup where myocarditis risk of vaccine exceeds that of the disease.
