Abstract Since SARS-CoV-2 BA. 5 (Omicron) emerged and spread in 2022, Omicron
lineages have markedly diversified. Here we review the evolutionary trajectories and …

Upon the emergence of SARS-CoV-2 in the human population, it was conjectured that for
this coronavirus the dynamic intra-host heterogeneity typical of RNA viruses would be toned …

The BQ and XBB subvariants of SARS-CoV-2 Omicron are now rapidly expanding, possibly
due to altered antibody evasion properties deriving from their additional spike mutations …

Continuous evolution of Omicron has led to a rapid and simultaneous emergence of
numerous variants that display growth advantages over BA. 5 (ref.). Despite their divergent …

The continuing emergence of SARS-CoV-2 variants highlights the need to update COVID-19
vaccine compositions. However, immune imprinting induced by vaccination based on the …

SARS-CoV-2 subvariants BQ. 1.1 and XBB. 1 have been circulating globally with superior
growth advantages over most omicron mutants (appendix p 5). However, XBB. 1.5, a …

Summary Recently emerged SARS-CoV-2 Omicron subvariant, BA. 2.75, displayed a growth
advantage over circulating BA. 2.38, BA. 2.76, and BA. 5 in India. However, the underlying …

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 …

Mutations in the SARS-CoV-2 genome could confer resistance to pre-existing antibodies
and/or increased transmissibility. The recently emerged Omicron subvariants exhibit a …
