The first dominant SARS‐CoV‐2 Omicron variant BA. 1 harbours 35 mutations in its Spike
protein from the original SARS‐CoV‐2 variant that emerged late 2019. Soon after its …

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 …

SARS-CoV-2 mRNA vaccination induces robust humoral and cellular immunity in the
circulation; however, it is currently unknown whether it elicits effective immune responses in …

Abstract Omicron BA. 2.86 subvariant differs from Omicron BA. 2 as well as recently
circulating variants by over 30 mutations in the spike protein alone. Here we report on the …

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 …
