While the antibody response to SARS-CoV-2 has been extensively studied in blood,
relatively little is known about the antibody response in saliva and its relationship to systemic …

Background: Detecting antibody responses during and after SARS-CoV-2 infection is
essential in determining the seroepidemiology of the virus and the potential role of antibody …

Background Whereas severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-
specific antibody tests are increasingly being used to estimate the prevalence of SARS-CoV …

Long-term antibody responses and neutralizing activities in response to SARS-CoV-2
infection are not yet clear. Here we quantify immunoglobulin M (IgM) and G (IgG) antibodies …

SARS‐CoV‐2 has emerged as a human pathogen, causing clinical signs, from fever to
pneumonia—COVID‐19—but may remain mild or asymptomatic. To understand the …

Background Declining humoral immunity in coronavirus disease 2019 (COVID-19) patients
and possible reinfection have raised concern. Mucosal immunity, particularly salivary …

We measured plasma and/or serum antibody responses to the receptor-binding domain
(RBD) of the spike (S) protein of SARS-CoV-2 in 343 North American patients infected with …

SARS-CoV-2 is responsible for the coronavirus disease 2019 (COVID-19) pandemic,
infecting millions of people and causing hundreds of thousands of deaths. The Spike …

The dynamics, duration, and nature of immunity produced during SARS-CoV-2 infection are
still unclear. Here, we longitudinally measured virus-neutralising antibody, specific …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of an ongoing
