“Despite the high efficacy of the BNT162b2 messenger RNA vaccine [Pfizer vaccine] against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), rare breakthrough infections have been reported, including infections among health care workers,” wrote the researchers.
At the largest medical centre in Israel, the researchers identified “breakthrough infections” by performing extensive evaluations of health care workers who were symptomatic (including mild symptoms) or had known infection exposure.
Among 1497 fully vaccinated health care workers for whom data were available, 39 breakthrough infections were documented.
