Now that hundreds of millions of doses of COVID-19 vaccines have been administered in the U.S., an abundance of safety data has been collected. While this data shows that COVID-19 vaccines are safe and effective at helping prevent infection, extremely rare adverse reactions can occur.

Myocarditis and pericarditis are conditions that have occurred following COVID-19 vaccination in a very small number of people. Most cases are mild, and individuals often recover on their own or with minimal treatment. Myocarditis and pericarditis are much more common if you get COVID-19. The risks to the heart from COVID-19 infection can be more severe.

Now a study in the US has analysed how often myocarditis occurs following infection with the coronavirus. Researchers analysed the records of healthcare organisations that cover a fifth of the US population. They found that, during the first 12 months of the pandemic, males aged 12 to 17 were most likely to develop myocarditis within three months of catching covid-19, at a rate of about 450 cases per million infections.

This compares with 67 cases of myocarditis per million males of the same age following their second dose of a Pfizer/BioNTech or Moderna vaccine, according to figures from the US Advisory Committee on Immunization Practices. Researchers added together cases after first and second doses to reach a total rate of 77 cases per million in this male age group triggered by vaccination, a sixth that seen after infection.
