Anti-Idiotype Antibodies against Spike Proteins may Explain Myocarditis

An article published in the New England Journal of Medicine proposed a mechanism for myocarditis after COVID-19 or COVID vaccination. Here is how it happens. During COVID-19 infection or after COVID vaccination, antibodies develop. Anti-spike protein antibodies bind to the spike proteins of the SARS-CoV-2. The antibodies prevent the virus from attaching to the ACE2…
