Just because you don’t know why doesn’t mean “no one knows why”. Myocarditis is a well known risk factor in vaccines and the Covid studies explicitly tested different dosages to determine the lowest effective dose to minimize that risk.

It’s pretty impressive how weird antivaxxers have convinced millions of people to not take vaccines based on their ignorance of the subject but here we are.

No it's not a well known risk factor at all. Especially not the likes of 1 in 5000, and there's no explanation why it's only affected kids 12-17 and it decreases to almost nil as one gets older.

What do you mean by "knows why"? Seriously - there's "no one knows why and can't point to anything at all that my be related", and there's "...and we don't know why the xyz protein doesn't match our models and we're not sure what's going on in the 4890th pair of the dna that generates it"?

Both fit "no one knows why" - and that's the problem with such statements.

If you're that concerned about things doctor's don't know about medication side effects then you probably shouldn't take any medicine ever. Almost every single one of them has some random side effect or risk that no one has yet figured out the exact mechanism for. Most aren't even quantified in random studies but simply noted and then utterly ignored. The vaccines being studied so much is why we have actual data on these rare side effects unlike most medications.

Fun fact: we're still not quite sure how acetaminophen/paracetamol (aka, Tylenol) works! https://pubmed.ncbi.nlm.nih.gov/18811827/
