A large body of evidence generated in the last two and a half years addresses the roles of T
cells in SARS-CoV-2 infection and following vaccination. Infection or vaccination induces …

The adaptive immune response is a major determinant of the clinical outcome after SARS-
CoV-2 infection and underpins vaccine efficacy. T cell responses develop early and …

Abstract The SARS-CoV-2 Omicron variant (B. 1.1. 529) has multiple spike protein
mutations, that contribute to viral escape from antibody neutralization,,–and reduce vaccine …

We address whether T cell responses induced by different vaccine platforms (mRNA-1273,
BNT162b2, Ad26. COV2. S, and NVX-CoV2373) cross-recognize early SARS-CoV-2 …

The severe acute respiratory distress syndrome coronavirus 2 (SARS-CoV-2) Omicron
variant is spreading rapidly, even in vaccinated individuals, raising concerns about immune …

The emergence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
Omicron (B. 1.1. 529) variant of concern (VOC) has destabilized global efforts to control the …

Immunological memory is the basis of protective immunity provided by vaccines and
previous infections. Immunological memory can develop from multiple branches of the …

Background Few data exist on the comparative safety and immunogenicity of different
COVID-19 vaccines given as a third (booster) dose. To generate data to optimise selection …

The past several months have witnessed the emergence of SARS-CoV-2 variants with novel
spike protein mutations that are influencing the epidemiological and clinical aspects of the …

Antibodies against epitopes in S1 give the most accurate CoP against infection by the SARS‐
