For 12 to 15-year-olds, the risk of myocarditis after the Pfizer shot is higher in boys than girls, according to Israeli researchers who calculated the risk in adolescents using nationwide data. The team used data from the Israeli Ministry of Health on over 400,000 adolescents and found that the risk of myocarditis is 1 case per 12,361 for boys and 1 case per 144,439 for girls. The team note that this is much higher than estimates for unvaccinated people, is lower than previously reported for males between 16 to 24 but higher than the Centres for Disease Control and Prevention's estimate for 12 to 17-year-olds.
