The European total was 145 cases of myocarditis on 177 million vaccinations. Assuming 2 vaccinations per person, that's 145 cases in 88.5 million people or a 0,00016% chance. That's less than 1 in 600.000 not the 3000 you claim.

And even then, a very big majority of the myocarditis cases were mild enough to go away on their own. Only 5 people died from it and all were elderly with other pre-existing conditions.
