Israeli study of almost 200,000 Covid positive cases and 600,000 non positive control cases, all before vaccines were introduced, concluded that Covid infection was not associated with increased myocarditis and pericarditis.
The Incidence of Myocarditis and Pericarditis in Post COVID-19 Unvaccinated Patients—A Large Population-Based Study
Myocarditis and pericarditis are potential post-acute cardiac sequelae of COVID-19 infection, arising from adaptive immune responses. We aimed to study the…
Post COVID-19 infection was not associated with either myocarditis (aHR 1.08; 95% CI 0.45 to 2.56) or pericarditis (aHR 0.53; 95% CI 0.25 to 1.13). We did not observe an increased incidence of neither pericarditis nor myocarditis in adult patients recovering from COVID-19 infection.
In other words, the Covid vaccines deserve a special place for causing heart damage. Even the Novavax vaccine may be associated with heart inflammation.
