comprehending the COVID-19 pandemic and preventing future coronavirus pandemics. In …

Abstract Recently, the SARS-CoV-2 variants from the United Kingdom (UK), South Africa,
and Brazil have received much attention for their increased infectivity, potentially high …

Summary The highly transmissible B. 1.1. 7 variant of SARS-CoV-2, first identified in the
United Kingdom, has gained a foothold across the world. Using S gene target failure (SGTF) …

The current pandemic of COVID-19 is fueled by more infectious emergent Omicron variants.
Ongoing concerns of emergent variants include possible recombinants, as genome …

SARS-CoV-2 has adapted in a stepwise manner, with multiple beneficial mutations
accumulating in a rapid succession at origins of VOCs, and the reasons for this are unclear …

SARS-CoV-2 variants of interest and concern will continue to emerge for the duration of the
COVID-19 pandemic. To map mutations in the receptor-binding domain (RBD) of the spike …

The sensitivity of SARS-CoV-2 variants of concern (VOCs) to neutralizing antibodies has
largely been studied in the context of key receptor binding domain (RBD) mutations …

The Omicron BA. 1 variant emerged in late 2021 and quickly spread across the world.
Compared to the earlier SARS-CoV-2 variants, BA. 1 has many mutations, some of which …

Evolutionary and functional studies suggested that the emergence of the Omicron variants
can be determined by multiple fitness trade-offs including the immune escape, binding …

A spike protein mutation D614G became dominant in SARS-CoV-2 during the COVID-19
pandemic. However, the mutational impact on viral spread and vaccine efficacy remains to …
