The clinical course and outcome of COVID-19 are highly variable, ranging from
asymptomatic infections to severe disease and death. Understanding the risk factors of …

The efficacy of virus-specific T cells in clearing pathogens involves a fine balance between
antiviral and inflammatory features. SARS-CoV-2–specific T cells in individuals who clear …

SARS-CoV-2 infection causes diverse outcomes ranging from asymptomatic infection to
respiratory distress and death. A major unresolved question is whether prior immunity to …

As an immune response to COVID-19 infection, patients develop SARS-CoV-2-specific
IgM/IgG antibodies. Here, we compare the performance of a conventional lateral flow assay …

Herein we measured CD4+ T-cell responses against common cold coronaviruses (CCC)
and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in high-risk health care …

Background Antibodies raised against human seasonal coronaviruses (sCoVs), which are
responsible for the common cold, are known to cross-react with SARS-CoV-2 antigens. This …

Serological assays detecting neutralising antibodies are important for determining the
immune responses following infection or vaccination and are also often considered a …

In this study, it was aimed to determine the antibody responses after the two doses of
inactivated severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) vaccinations in …

Effective humoral immune responses require well-orchestrated B and T follicular helper (Tfh)
cell interactions. Whether these interactions are impaired and associated with COVID-19 …

Characterization of the naturally acquired B and T cell immune responses to severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) is important for the development of …
