A rare side-effect of the mRNA SARS-CoV-2 vaccines may be more common than previously believed, according to a new study conducted in Oregon, with additional research suggesting the risk for the side-effect increases dramatically among males under 40 with each additional dose of the vaccine.

The first study, conducted by doctors in Portland from the Kaiser Permanente healthcare provider network, examined incidents of two kinds of heart inflammation - myocarditis and pericarditis -from the Kaiser Permanente database.

Both the Moderna and Pfizer-BioNTech mRNA vaccines have been linked in a number of cases to heart inflammation, particularly in younger male recipients of the vaccine.
