Why the study?
To assess the association between the single-dose COVID-19 BNT162b2 vaccination regimen and myocarditis risk among vaccinated adolescents in Hong Kong before and after the single-dose policy.
Does a single-dose COVID-19 BNT162b2 vaccination regimen affect myocarditis risk in adolescents compared to the regimen before the single-dose policy?
Does a single-dose COVID-19 BNT162b2 vaccination regimen affect myocarditis risk in adolescents compared to the regimen before the single-dose policy?
Single-dose BNT162b2 was associated with lower myocarditis risk; supports hypothesis-generating evaluation of adolescent dosing strategies but should not yet change practice.
