FDA researchers detected a safety signal for seizures in children ages 2-4 following mRNA COVID-19 vaccination, according to a study published Wednesday in JAMA Network Open. A preprint study published last month found similar results.

Researchers analyzing near-real-time monitoring data on vaccinated children identified this new safety signal in children ages 2-4 who received the original Pfizer vaccine (BNT162b2) and children ages 2-5 who received the original Moderna vaccine (mRNA-1273).

The researchers also identified a safety signal for myocarditis or pericarditis following the Pfizer vaccine in adolescents ages 12-17.
