The new predominant circulating SARS-CoV-2 variant, Omicron, can robustly escape
current vaccines and neutralizing antibodies. Although Omicron has been reported to have …

Background The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron
(B. 1.1. 529) variant has proven to be highly transmissible and has outcompeted the Delta …

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Omicron variant is
becoming a dominant circulator and has several mutations in the spike glycoprotein, which …

Since its discovery in 2019, multiple variants of severe acute respiratory syndrome
coronavirus-2 (SARS-CoV-2) have been identified. This study investigates virus spread and …

Since the first SARS‐CoV‐2 outbreak in late 2019, the SARS‐CoV‐2 genome has harbored
multiple mutations, especially spike protein mutations. The currently fast‐spreading Omicron …

The mutation profile of the SARS-CoV-2 Omicron variant poses a concern for naturally
acquired and vaccine-induced immunity. We investigated the ability of prior infection with an …

ABSTRACT The Omicron BA. 1 (B. 1.1. 529) SARS-CoV-2 variant is characterized by a high
number of mutations in the viral genome, associated with immune escape and increased …

Summary Background SARS-CoV-2 Omicron variant is rampantly spreading across the
globe. We assessed the pathogenicity and immune response generated by BA. 1.1 sub …

The diversity of SARS-CoV-2 mutations raises the possibility of reinfection of individuals
previously infected with earlier variants, and this risk is further increased by the emergence …

The newly emerging SARS-CoV-2 Omicron (B. 1.1. 529) variant first identified in South
Africa in November 2021 is characterized by an unusual number of amino acid mutations in …
