Another study found that antibodies against COVID-19 spike glycoproteins could cross-react with structurally similar human peptide protein sequences, such as α-myosin (52), making the molecular mimicry between the self-antigens and the spike protein of COVID-19 another possible mechanism for mRNA COVID-19 vaccination associated myocarditis/pericarditis. Here, CHMP5 is linked to pericarditis.
