Again and again there were reports of people who suffered heart muscle inflammation (myocarditis) after fighting the Coronavirus had been vaccinated. According to a recent study, which was published in the journal “Circulation”.is an inflammation of the heart muscle after a COVID-19 infection however, much more often than after vaccination against the disease.

The data was analyzed from around 43 million people aged 13 and over in Great Britain. The prerequisite was that the people had been vaccinated against the corona virus one or more times. Around six million of these people fell ill with COVID-19 during the test period. A total of 2,861 people developed myocarditis, 617 of whom developed myocarditis immediately after vaccination.

The risk of myocarditis was increased 28 days after receiving the first AstraZeneca vaccination or after the first, second or booster vaccination with the Biontech/Pfizer or Moderna vaccine. Nevertheless, it was much lower than the risk of being diagnosed with myocarditis after a COVID infection.

In women over 40, there were two to three cases of myocarditis in every million vaccinated women who were vaccinated with Pfizer’s vaccine. A total of 51 cases of myocarditis have been identified after infection with the coronavirus. In the group of unvaccinated men under 40, there were 16 cases of myocarditis per million infected.

“The risk of developing myocarditis after a COVID-19 vaccine is low,” concludes Professor Nicholas Mills from the University of Edinburgh. “This risk should be weighed against the benefits in preventing severe COVID-19 infection,” he said.
