A new study of U.S. service members found higher than expected rates of heart inflammation following receipt of a COVID vaccine. It’s a finding Defense Department researchers say should call attention to the condition, known as myocarditis, as a potential side effect of vaccinations.
In a study published June 29 in JAMA Cardiology, U.S. military physicians described 23 cases of myocarditis in previously healthy males who developed the condition within four days of receiving a COVID vaccine.
A total of 23 male patients (22 currently serving in the military and 1 retiree) with a median age range of 25 years were evaluated between January and April 2021 for acute-onset chest pain following vaccination with an mRNA COVID vaccine.
