Prior SARS-CoV-2 infection is associated with protection against symptomatic reinfection

Aidan T Hanrath et al. J Infect. 2021 Apr.

Abstract

  1. •

    Whether SARS-CoV-2 infection confers immunity to reinfection is uncertain.

  2. •

    The ‘second wave’ of transmission offered an opportunity to examine this.

  3. •

    We observed no symptomatic reinfections in a cohort of healthcare workers.

  4. •

    This apparent immunity to re-infection was maintained for at least 6 months.

  5. •

    Further studies are required to define immunological mechanism(s) and durability.

Keywords: Antibody; COVID-19; Healthcare workers; Immunity; Protection.
