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 …

Having adopted a dynamic zero-COVID strategy to respond to SARS-CoV-2 variants with
higher transmissibility since August 2021, China is now considering whether, and for how …

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 …

Currently circulating SARS-CoV-2 variants have acquired convergent mutations at hot spots
in the receptor-binding domain (RBD) of the spike protein. The effects of these mutations on …

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 highly mutated SARS-CoV-2 Omicron (B. 1.1. 529) variant has been shown to evade a
substantial fraction of neutralizing antibody responses elicited by current vaccines that …

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

Abstract Background The B. 1.1. 529 (omicron) variant of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) was first identified on November 25, 2021, in Gauteng …

Summary Background Several SARS-CoV-2 variants of concern have been identified that
partly escape serum neutralisation elicited by current vaccines. Studies have also shown …
