- The Click Times: The overall risk of myopericarditis (inflammation of the heart muscle and lining around the heart) after a Covid vaccination is low and not significantly different from people who are vaccinated against other diseases, according to analysis of 22 studies using databases of international data from 1947 to December 2021.
- The analysis, which included around 395 million doses of the Covid19 vaccine, including around 300 million mRNA vaccines from Pfizer and Moderna and almost 10 million doses of non-Covid vaccines, found 18 cases of myopericarditis per million doses of the Covid19 vaccine in the world Compared to 56 cases per million doses. for non-Covid vaccines such as influenza.
- The risk of myopericarditis was almost four times higher in those who received an mRNA Covid vaccine compared to a non-mRNA Covid vaccine and in those who received the second dose compared to the first or third, the researchers found.
- The risk was significantly higher in young men under 30, which was 10 times higher than women of the same age, the researchers said, and the rate in men over 30 was about three times higher than in women over 30.
- Study co-author Dr . Jyoti Somani, an infectious disease specialist at the National University Hospital of Singapore, said the results were intended to highlight the fact that the risks of rare adverse events “need to be outweighed by the benefits of vaccination, which include a reduced risk of infections, hospitalization, severe disease, and death.”

Covid19 carries a greater risk of heart problems, among a host of other issues. The researchers found that 1.1% of 2.5 million people hospitalized with Covid19 showed signs of myopericarditis. Although not directly comparable to vaccination results (problems were measured differently), the rate suggests a much higher incidence in those infected with the virus than in those who received the vaccine. The finding is consistent with other studies on the subject, including those from the Centers for Disease Control and Prevention.
