Accumulating evidence suggests that severe acute respiratory syndrome coronavirus 2
(SARS‐CoV‐2) impairs the adaptive immune system during acute infection. Still, it remains …

Background There is an imperative need to determine the durability of adaptive immunity to
SARS-CoV-2. We enumerated SARS-CoV-2-reactive CD4+ and CD8+ T cells targeting S1 …

COVID-19 generates SARS-CoV-2-specific antibodies in immunocompetent individuals.
However, in immunocompromised patients, the humoral immunity following infection may be …

Background The severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) immune
response is crucial for disease management, although diminishing immunity raises the …

Background The longitudinal antigen-specific immunity in COVID-19 convalescents is
crucial for long-term protection upon individual re-exposure to SARS-CoV-2, and even more …

The characterization of cell‐mediated and humoral adaptive immune responses to SARS‐
CoV‐2 is fundamental to understand COVID‐19 progression and the development of …

Safe and effective vaccines and therapeutics based on the understanding of antiviral
immunity are urgently needed to end the COVID-19 pandemic. However, the understanding …

Objectives There is emerging evidence that SARS‐CoV‐2‐specific memory T‐cell
responses are likely to provide critical long‐term protection against COVID‐19. Strategies to …

Summary The World Health Organization has declared SARS-CoV-2 virus outbreak a
worldwide pandemic. However, there is very limited understanding on the immune …

The WHO has declared SARS-CoV-2 outbreak a public health emergency of international
concern. However, to date, there was hardly any study in characterizing the immune …
