The unique adaptability of mRNA vaccines makes them promising tools for addressing both infectious and non-infectious diseases, including cancers.1 Therefore, it is critical to understand any potential adverse effects of this technology.
COVID-19 mRNA vaccinations have been associated with an increased risk of myocarditis/pericarditis, though the magnitude and severity of complications are much lower than those caused by a SARS-CoV-2 infection.2 Data collected on the Vaccine Safety Datalink since December 2020 show that the incidence of symptomatic myocarditis/pericarditis is highest among young adult males.3 This is the same demographic that predominates the US active-duty service member population.
