In short, the mechanism in those rarest of rare cases is not typical even for immune related cardiomyopathy, but it is important to evaluate chances of it happening for future vaccine adjuvants and administration routes. The adjuvants used in the COVID vaccines are rather hardcore as far as these things go, hence the common side effects (non-cardiac). For what they do, it is rather remarkable on how safe the thing turns out... And they have to be, or the response is worse. The chances are side effects could be reduced if we get the mucosal vaccines ready.
