Summary Background The SARS-CoV-2 omicron (B. 1.1. 529) variant, which was first
identified in November, 2021, spread rapidly in many countries, with a spike protein highly …

The emerging new VOC B. 1.1. 529 (Omicron) variant has raised serious concerns due to
multiple mutations, reported significant immune escape, and unprecedented rapid …

Background and Methods The SARS-CoV-2 (severe acute respiratory syndrome
coronavirus 2) Omicron (B. 1.1. 529) variant is the antigenically most distinct variant to date …

The recent emergence of the SARS-CoV-2 Omicron variant is raising concerns because of
its increased transmissibility and its numerous spike mutations, which have the potential to …

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 …

Early indications from South Africa and the United Kingdom signal that the fast-spreading
Omicron variant of the coronavirus SARS-CoV-2 is less dangerous than its predecessor …

Background Rapid spread of the omicron SARS-CoV-2 variant despite extensive
vaccination suggests immune escape. The neutralising ability of different vaccines alone or …

Omicron, the most recent SARS-CoV-2 variant of concern (VOC), harbours multiple
mutations in the spike protein that were not observed in previous VOCs. Initial studies …

Decreased Neutralization of Omicron Subvariants In a small study involving 54 participants,
