The findings of a study published in the journal Science Immunology showed that heart inflammation following COVID-19 vaccination was caused by a more generalized response involving immune cells and inflammation.

The researchers from Yale University, US, stated that among individuals with heart inflammation, the immune system was found to be overstimulated, leading to the overproduction of cytokines and cellular responses. The research team examined the immune system responses in those rare cases of myocarditis among vaccinated individuals for the study.

When the COVID-19 vaccines were first administered two years ago, public health officials discovered an increase in cases of myocarditis, an inflammation of the heart muscle, primarily in males in their teens or early twenties. The affected individuals received mRNA vaccines designed to elicit immune responses specific to the SARS-CoV-2 virus. Previous studies have shown that extending the interval between immunization doses from four to eight weeks can minimize the chance of developing myocarditis.

Lead researcher Dr. Carrie Lucas, associate professor of immunobiology at the university, noted that, according to the data given by the Centres for Disease Control and Prevention (CDC), the risk of myocarditis is significantly higher in unvaccinated individuals who contract the COVID-19 virus than in those who are vaccinated. Hence, she emphasized that vaccination can offer the best protection from COVID-19-related diseases.
