Data from Israel: myocarditis after COVID-19 vaccines remain rare, highest risk in young males.

Among males ages 16 to 19 years, approximately 1 in 15,000 developed myocarditis after a booster dose of the Pfizer-BioNTech COVID-19 vaccine.

All confirmed cases of myocarditis were mild and resolved after a short hospital stay (average of 3.5 days), and no hospital readmissions were reported in the following 90 days.
