Protection following BNT162b2 booster in adolescents substantially exceeds that of a fresh 2-dose vaccine
Abstract
This study compares SARS-CoV-2 infection rates following a recent second or third dose of the BNT162b2 (Pfizer/BioNTech) vaccine. They use data from Israel for 12–14 year olds (second dose) and 16–18 year olds (third dose), and find a 3.7-fold higher risk in the second-dose group.
