“Conclusions and Relevance Among 20 health outcomes that were monitored in near real time, a safety signal was identified for only myocarditis or pericarditis. Consistent with other published reports, these results provide additional evidence that COVID-19 vaccines are safe in children.”
"It should be noted that either myocarditis or pericarditis is a rare event, with an average incidence of 39.4 cases per million doses administered in children aged 5 to 17 years within 7 days after BNT162b2 COVID-19 vaccination."
Of course, 39.4/1,000,000 versus Whatever COVID-19 does to kids, assuming reporting for that is correct as well.
