Our report found post-vaccination CAE rates following dose two of 162.2 and 94.0/million for
boys 12-15 and 16-17, respectively. For boys with no underlying health conditions, the chance of
either CAE, or hospitalization for CAE, after their second dose of mRNA vaccination are
considerably higher than their 120-day risk of COVID-19 hospitalization, even at times of peak
disease prevalence. The long-term consequences of this vaccine-associated cardiac inflammation
are not yet fully defined and should be studied. In lieu of pediatric vaccination mandates, the US
may: 1) consider gathering data on previous infection in this age group and/or 2) follow the
example of Germany,[31] Sweden [32], Norway [33] and the WHO[34] and hold off on
definitively recommending vaccination of low-risk children against COVID-19, or 3) offer one
dose to adolescents as the UK has just announced [35] while more information about risks,
benefits, harms and alternative dosing or vaccination strategies are studied and considered.
