Humoral immune responses are typically characterized by primary IgM antibody responses
followed by secondary antibody responses associated with immune memory and composed …

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes
coronavirus disease 2019 (COVID-19), primarily infects cells at mucosal surfaces. Serum …

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 …

Understanding humoral immune responses to SARS-CoV-2 infection will play a critical role
in the development of vaccines and antibody-based interventions. We report systemic and …

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 …

Although SARS-CoV-2 infects the upper respiratory tract, we know little about the amount,
type, and kinetics of antibodies (Ab) generated in the oral cavity in response to COVID-19 …

The fate of protective immunity following mild severe acute respiratory syndrome-
coronavirus-2 (SARS-CoV-2) infection remains ill defined. Here, we characterize 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 …

Background A longitudinal study was performed to determine the breadth, kinetics, and
correlations of systemic and mucosal antibody responses to severe acute respiratory …

Background Most studies of immunity to SARS-CoV-2 focus on circulating antibody, giving
limited insights into mucosal defences that prevent viral replication and onward …
