Two studies looking at cases of myocarditis following vaccination with the Pfizer COVID-19 vaccine have confirmed that young men are at the highest risk. One study found there were around 2.13 cases of myocarditis per 100,000 people, but in young men aged 16 to 29, the risk was 10.69 cases per 100,000 people. The second study confirmed that the incidence of myocarditis, although low, increased after the receipt of the Pfizer vaccine. It found that the risk was higher after the second dose especially among young male recipients. Both studies also confirmed that most cases of myocarditis were mild or moderate in severity.
