Breakthrough SARS-CoV-2 infections after COVID-19 immunization

Joshua Hirsh et al. J Investig Med. 2022 Aug.

Abstract

As no vaccines are 100% effective at preventing illness, COVID-19 vaccine breakthrough cases are expected. We here aim to review the most recent literature on COVID-19 vaccine breakthrough infections. SARS-CoV-2 breakthrough infections are, in general, rare. Age may still be a factor in SARS-CoV-2 infections in immunized individuals.

Keywords: COVID-19; viral vaccines.
