Are SARS-CoV-2 Specific Antibodies a Correlate for Protection?

Status: Active, not recruiting
Location: See all (2) locations...
Intervention Type: Diagnostic Test
Study Type: Interventional
Study Phase: Not Applicable

The objectives of this study are (1) to determine the ex vivo neutralizing capacity and the longevity of SARS-CoV-2-specific Ab responses and (2) to measure the memory B-cell responses in a cohort of health care workers (HCW) recovering from severe, mild or asymptomatic infection. By focusing on HCW, a population that is at risk for re-infection during a second epidemic wave, the correlation between nAb levels and protection is investigated.
