Assessing the risk of myocarditis post COVID vaccination.

Yale University researchers have found that young men who are fully vaccinated against COVID-19 face an increased risk of myocarditis, a rare but serious condition. However, the risk of myocarditis is higher among those who are unvaccinated and get COVID-19 than from getting the vaccine. The condition was caused by a generalized response involving immune cells and inflammation, not the vaccine's antibodies. The researchers noted the small sample size of its study and said the benefits of the COVID-19 vaccine far exceed the risks.
