 The study found that there was an increased risk of myocarditis and pericarditis in people who had received either mRNA, Valve 73 or BN162B2 vaccines. This risk was higher in younger men, especially those who had previously been infected with SARS-CoV-2. Additionally, the risk was higher in people who had received a second dose of the vaccine, as opposed to a third dose.
