You keep quoting this research like it is something special. The EMA has know this for quite some time to be in the 1-10 in 100000 and more prevailant in males aging 12-35. It either goes away by itself or with medication though you are advised to seek medical attention if you feel anything strange. At least where I live no cases are known of death due this in stark contrast to the actual desease.
From the paper, 3rd paragraph from the end in the "Main" section:
> "First, we confirm and extend our previous findings in more than 42 million persons that the risk of hospitalization or death from myocarditis following COVID-19 infection is higher than the risk associated with vaccination in the overall population."
Quick edit: while I was skimming the paper someone else commented exactly this excerpt, hehe.
