The highly transmissible Omicron (B. 1.1. 529) variant of severe acute respiratory syndrome
coronavirus 2 (SARS-CoV-2) was first detected in late 2021. Initial Omicron waves were …

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 continued evolution of SARS-CoV-2 has led to the emergence of several new Omicron
subvariants, including BQ. 1, BQ. 1.1, BA. 4.6, BF. 7, and BA. 2.75. 2. Here, we examine the …

behavioural factors continue to undercut the response to the COVID-19 pandemic 1, 2. Here …

Abstract Omicron BA. 2.86 subvariant differs from Omicron BA. 2 as well as recently
circulating variants by over 30 mutations in the spike protein alone. Here we report on the …

In response to the emergence of SARS-CoV-2 variants of concern, the global scientific
community, through unprecedented effort, has sequenced and shared over 11 million …

Studies have reported reduced natural SARS-CoV-2 infection-and vaccine-induced
neutralization against omicron BA. 4/BA. 5 compared with earlier omicron subvariants. This …
