Convergent evolution of SARS-CoV-2 Omicron BA. 2, BA. 4, and BA. 5 lineages has led to
the emergence of several new subvariants, including BA. 2.75. 2, BA. 4.6. and BQ. 1.1. 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 …

Summary SARS-CoV-2 Omicron BA. 2.75 has diversified into multiple subvariants with
additional spike mutations and several are expanding in prevalence, particularly CH. 1.1 …

The SARS-CoV-2 Omicron (B. 1.1. 529) variant first emerged as the BA. 1 sub-lineage, with
extensive escape from neutralizing immunity elicited by previous infection with other …

The unceasing circulation of SARS-CoV-2 leads to the continuous emergence of novel viral
sublineages. Here, we isolate and characterize XBB. 1, XBB. 1.5, XBB. 1.9. 1, XBB. 1.16. 1 …

Abstract The SARS-CoV-2 Omicron variant (B. 1.1. 529) has three major lineages BA. 1, BA.
2, and BA. 3 1. BA. 1 rapidly became dominant and has demonstrated substantial escape …

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 …

Recently, a number of new Omicron subvariants related to BA. 4/5 and BA. 2.75 have
emerged and shown remarkable antibody evasion capacities, in particular BF. 7, BQ. 1, BQ …

The recent emergence of the Omicron BA. 1 and BA. 2 variants with heavily mutated spike
proteins has posed a challenge to the effectiveness of current vaccines and to monoclonal …

Summary In November 2021, Omicron BA. 1, containing a raft of new spike mutations,
emerged and quickly spread globally. Intense selection pressure to escape the antibody …
