A new study find that Heart inflammation post Covid vaccination was not caused by antibodies created by the vaccination, rather it was the result of a more generalised response involving immune cells and inflammation.
The increased incidence of myocarditis was seen basically in males, who had been vaccinated with mRNA vaccines, which designed to elicit immune responses specifically to the SARS-CoV-2 virus.
There have been reports of myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining surrounding the heart) occurring in a small number of people after receiving certain COVID-19 vaccines, particularly in young males.
The exact cause of this side effect is not yet fully understood, but it is believed to be related to an immune response triggered by the vaccine. The mRNA vaccines (Pfizer-BioNTech and Moderna) have been associated with a higher risk of myocarditis, while the viral vector vaccines (Johnson & Johnson and AstraZeneca) have been associated with a lower risk.
It's important to note that the risk of developing myocarditis or pericarditis after receiving a COVID-19 vaccine is very rare, and the benefits of vaccination in preventing severe COVID-19 outweigh the potential risks of this side effect. The Centers for Disease Control and Prevention (CDC) and other health organizations continue to recommend COVID-19 vaccination for everyone aged 12 and older.
