The T cell memory response is a crucial component of adaptive immunity responsible for
limiting or preventing viral reinfection. T cell memory after infection with the SARS-CoV-2 …

The efficacy of COVID-19 vaccines varies between individuals and populations, and the
reasons for this are still not fully understood. Recent clinical studies and animal models have …

Introduction The key to understanding the COVID-19 correlates of protection is assessing
vaccine-induced immunity in different demographic groups. Young people are at a lower risk …

Introduction The heterogeneity of the immunocompromised population means some
individuals may exhibit variable, weak or reduced vaccine-induced immune responses …

The potential future burden of COVID-19 is determined by the level of susceptibility of the
population to infection. The protective effect provided by those previously infected …

Background & Aims Comparative assessments of immunogenicity following different COVID-
19 vaccines in patients with distinct liver diseases are lacking. SARS-CoV-2-specific T-cell …

Serological correlates of protection against severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) infection after vaccination (“vaccine breakthrough”) have been described …

Introduction The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute
respiratory syndrome coronavirus 2 (SARS-CoV-2) has highlighted the danger posed by …

Virus-specific antibodies are crucial for protective immunity against SARS-CoV-2. Assessing
functional antibodies through conventional or pseudotyped virus neutralisation tests (pVNT) …

Solid cancer patients are at higher risk of SARS‐CoV‐2 infection and severe complications.
