"That’s not to say that there isn’t a plausible biological mechanism by which mRNA vaccination causes myocarditis directly – there is: the lipid nanoparticles, not confined to the injection site (as regulators had incorrectly assumed), travel throughout the circulation. Heart muscle cells are then “transfected” by mRNA, express spike protein and are then attacked by the patient’s own T-cells. This mechanism has been evidenced by a number of published autopsy reports (for example this) in which spike protein, but not the “N protein”, together with accompanying T cell infiltration was found in the hearts of the deceased who had died from myocarditis. Presence of spike protein with an absence of N protein is essentially determinative of vaccine, rather than viral, origin. Via a synergistic effect the actual risk may be raised even further; vaccination prior to infection may somehow “prime” the immune system such that subsequent infection increases the risk of such an autoimmune attack. Such a mechanism, called “molecular mimicry” is thought to be the underlying cause of myocarditis secondary to other viral infections."
