Strong data from a peer reviewed article in the journal of Clinical Infectious Disease shows that there is a significant increase in the risk of myocarditis/pericarditis following Comirnaty vaccination among Chinese male adolescents, especially after the second dose. Onset of myocarditis was a median of 2 days after vaccination. The clinically significant (acute and/or “mild”) myocarditis/pericarditis incidence rate came in at one out of every 2680 young males.
