Antibody Status and Incidence of SARS-CoV-2 Infection in Health Care Workers

S. F. Lumley et al.

Summary: In a longitudinal study of seropositive and seronegative health care workers undergoing asymptomatic and symptomatic SARS-CoV-2 testing, the presence of anti-spike or anti-nucleocapsid IgG antibodies was associated with a substantially reduced risk of SARS-CoV-2 reinfection in the ensuing 6 months.

Systemic and mucosal antibody responses specific to SARS-CoV-2 during mild versus severe COVID-19

Carlo Cervia et al.

Summary: The study found that severe COVID-19 patients experienced a significant increase in SARS-CoV-2 antibody titers after symptom onset, especially with high IgA titers, while mild cases may exhibit transient production of SARS-CoV-2-specific antibodies. Interestingly, some healthcare workers with negative serum antibody titers showed SARS-CoV-2-specific IgA in mucosal fluids with virus-neutralizing capacity in some cases.
