Does the incidence of reported myocarditis or pericarditis after BNT162b2 vaccination vary by age, sex, and inter-dose interval among adolescents aged 12 to 17?

In a recent article published in JAMA Pediatrics, researchers conducted a population-based cohort study among 12 to 17-year-old adolescents in Ontario, Canada, to estimate the incidence of myocarditis or pericarditis after BNT162b2 vaccination. In addition, they determined whether these estimates…

Underlying genetic cause for MIS-C complications after COVID-19 identified

Unvaccinated individuals exhibit significant clinical variability during primary infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the causal agent of the ongoing coronavirus disease 2019 (COVID-19) pandemic. Notably, common genetic factors serve as modest risk factors for…
