Abstract Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) is the causative
agent of the pandemic disease COVID-19, which is so far without efficacious treatment. The …

Two and a half years into the COVID-19 pandemic, we have gained many insights into the
human antibody response to the causative SARS-CoV-2 virus. In this Review, we …

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 …

Omicron Neutralization and mRNA-1273 Boosters Neutralization of the omicron variant was
assessed in serum samples obtained from persons who had received an mRNA-1273 …

On 24 th November 2021, the sequence of a new SARS-CoV-2 viral isolate Omicron-B. 1.1.
529 was announced, containing far more mutations in Spike (S) than previously reported …

Summary The SARS-CoV-2 Omicron variant with increased fitness is spreading rapidly
worldwide. Analysis of cryo-EM structures of the spike (S) from Omicron reveals amino acid …

Abstract Omicron (B. 1.1. 529), the most heavily mutated SARS-CoV-2 variant so far, is
highly resistant to neutralizing antibodies, raising concerns about the effectiveness of …

Omicron SARS-CoV-2 is rapidly spreading worldwide. To delineate the impact of emerging
mutations on spike's properties, we performed systematic structural analyses on apo …

Neutralizing antibodies can block infection, clear pathogens, and are essential to provide
long-term immunity. Since the onset of the pandemic, SARS-CoV-2 neutralizing antibodies …

Waning SARS-CoV-2 Immunity in Qatar The protection afforded by the mRNA-1273 vaccine
against SARS-CoV-2 infection in Qatar seemed to wane over several months after …
