Persistence of SARS-CoV-2 N-antibody response in healthcare workers, London, UK

Abstract

Prospective serosurveillance of severe acute respiratory syndrome coronavirus 2 in 1,069 healthcare workers in London, UK, demonstrated that nucleocapsid antibody titers were stable and sustained for ≤12 weeks in 312 seropositive participants. This fi nding was consistent across demographic and clinical variables and contrasts with reports of short-term antibody waning.
