A British research team analyzed that the risk of developing myocarditis, a typical adverse reaction experienced after vaccination against COVID-19 (COVID-19), is about 11 times higher if the person is infected with COVID-19 without the vaccine than after vaccination.
Julia Hippiesleycox, a professor of clinical epidemiology at Oxford University, UK, analyzed about 43 million people over the age of 13 living in the UK and published the results of this study in the international scientific journal ‘Circulation’ on the 22nd. Between December 1, 2020 and December 15, 2021, AstraZeneca, Janssen, Pfizer, and Moderna received one or more doses of the COVID-19 vaccine.
Myocarditis is an inflammation of the heart muscle. According to the American Heart Association’s scientific statement on myocarditis released last year, about 10 to 20 out of every 100,000 people in the general population are diagnosed with myocarditis each year.
According to the analysis of the research team, 2,861 people were hospitalized or died due to myocarditis out of about 43 million people. The probability of developing myocarditis is about 0.007%. Of the 2,861 people, 617 developed myocarditis between 1 and 28 days after receiving the COVID-19 vaccine, and 514 were hospitalized.
As a result of their analysis, it was found that people who were infected with COVID-19 before receiving the vaccine were 11 times more likely to develop myocarditis between 1 and 28 days after they tested positive than when they contracted COVID-19 after receiving the vaccine. “The chance of developing myocarditis was cut by half if the vaccine was given at least once,” the research team explained.
“It is important for the public to understand that myocarditis itself is rare and the risk of developing myocarditis after vaccination is rare,” said the research team. Further analysis is needed.”
