ABSTRACT
A cohort consisting of asymptomatic health care workers (HCW) donated temporal serum samples following infection with SARS-CoV-2. Analysis shows that all asymptomatic HCW had neutralizing antibodies, that these antibodies persist for at least 60 days, and that anti-spike RBD IgG levels were correspondingly durable over the same time period.
