That isn't relevant because there is no evidence that the vaccine reduces your risk of suffering from myocarditis after infection. (It isn't even necessarily true, but that is a separate matter).
> The risk of COVID-19 infection-related myocarditis risk was cut in half among people infected after vaccination (received at least one dose of a COVID-19 vaccine).
Based on the original strain. Not that I would want to argue. There are several nations that do not recommend vaccination for younger people. They could be wrong of course, but to be so certain about science of a rapidly changing virus and wave away methodological difficulties, like measuring myocarditis without an autopsy, strikes me as scientifically naive, perhaps bordering on religiosity.
