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

Antibodies against epitopes in S1 give the most accurate CoP against infection by the SARS‐
CoV‐2 coronavirus. Measurement of those antibodies by neutralization or binding assays …

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 …

We provide two methods for monitoring reinfection trends in routine surveillance data to
identify signatures of changes in reinfection risk and apply these approaches to data from …

The Omicron variant of SARS-CoV-2 infected many vaccinated and convalescent
individuals,–. Despite the reduced protection from infection, individuals who received three …

RNA vaccines are efficient preventive measures to combat the severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2) pandemic. High levels of neutralizing SARS-CoV-2 …

INTRODUCTION Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA
vaccines are highly effective at preventing infection and especially severe disease …

The COVID-19 global pandemic caused by the severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) infection has infected hundreds of millions of individuals …

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 …

SARS-CoV-2 vaccines are crucial in controlling COVID-19, but knowledge of which factors
determine waning immunity is limited. We examined antibody levels and T-cell gamma …
