And better still, the severity of postvaccination myocarditis is much less than post-infection myocarditis. However, the prognosis for myocarditis after COVID-19 vaccination appears to be much less severe. In a study of nearly 4 million residents of Hong Kong, only one death occurred (1%) among 104 cases of postvaccination myocarditis, compared with 84 deaths (11 percent) among 762 cases of viral infection-related myocarditis (HR 0.08, 95% CI 0.01-0.57). In a surveillance study of cases of myocarditis related to COVID-19 vaccination in the United States reported to VAERS, among 484 hospitalizations there were no deaths, and evidence of ongoing myocarditis at follow-up cardiac MR was uncommon (13 percent)
