Yes, I’m sure most doctors don’t put anything in the medical records about the vax likely being the cause of the problem.
But insurance companies have to notice something is up.
For instance, Aetna executives have to be all like, “From 2010 to 2020 we had 100 total claims for myocarditis in people under 25 and now in 2021 we have seen 35 claims for such people.”
Oh yes, they notice, but what can they do?
