TL;DR: Four serological assays measuring anti–SARS-CoV-2 antibodies and their neutralizing activity in samples from individuals with severe and mild COVID-19 are compared and enabled a broad evaluation of SARS- CoV- 2 seroprevalence and antibody profiling in different subpopulations within one region.
Journal ArticleDOI
Serum neutralization of SARS-CoV-2 Omicron sublineages BA.1 and BA.2 in patients receiving monoclonal antibodies

TL;DR: In this paper , the sensitivity of BA.1 and BA.2 to neutralization by nine therapeutic monoclonal antibodies (mAbs) was compared, and it was found that BA. 2 was sensitive to cilgavimab, partly inhibited by imdevimab and resistant to adintrevimab.

TL;DR: It is shown that SARS-CoV-2 infected cells express the viral Spike protein at their surface and fuse with ACE2-positive neighbouring cells, which facilitates syncytia formation and thwarts the antiviral effect of IFITMs.
Journal ArticleDOI
Rapid decline of neutralizing antibodies against SARS-CoV-2 among infected healthcare workers.

TL;DR: In this paper, the persistence of neutralizing antibodies (NAbs) among SARS-CoV-2-infected healthcare workers (HCW) was found to be lost in association with a decrease in systemic IgA antibody levels.
Journal ArticleDOI
Evolution of antibody responses up to 13 months after SARS-CoV-2 infection and risk of reinfection.

TL;DR: In this article, a prospective, monocentric, longitudinal, cohort clinical study was conducted to assess the kinetics of SARS-CoV-2 antibodies and the incidence of reinfection.
