True. Myocarditis does damage to the heart muscle that doesn't repair itself. I just searched Google for the same terms I did a couple of months ago and found different answers about this. Before there was multiple sites referencing the long term mortality rate being about 11 years. Today all those links are no coming up. Tons of links saying mild myocarditis doesn't cause long term effects now. Data skewing driven links.

My husband had periocarditis a couple years ago and almost died. So I checked long term effects of both periocarditis any myocarditis. These are both life threatening conditions. There should be no allowable cases connected to their shot that is acceptable.
