As the fifth variant of concern of the SARS‐CoV‐2 virus, the Omicron variant (B. 1.1. 529)
has quickly become the dominant type among the previous circulating variants worldwide …

Since its emergence at the end of 2019, severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) has caused the infection of more than 600 million people worldwide and has …

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 …

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 …

Omicron subvariants continuingly challenge current vaccination strategies. Here, we
demonstrate nearly complete escape of the XBB. 1.5, CH. 1.1, and CA. 3.1 variants from …

Pan-betacoronavirus neutralizing antibodies may hold the key to developing broadly
protective vaccines against novel pandemic coronaviruses and to more effectively respond …

Immune evasion by SARS-CoV-2 paired with immune imprinting from monovalent mRNA
vaccines has resulted in attenuated neutralizing antibody responses against Omicron …

New Immunogens Needed for Emerging Omicron Variants Emerging omicron subvariants
express additional spike mutations that escape detection by neutralizing antibodies elicited …

Co-infection with multiple SARS-CoV-2 lineages can result in recombination of the viral
genomes and the emergence of novel, recombinant SARS-CoV-2 lineages. 1–4 In January …

Evolution of SARS-CoV-2 requires the reassessment of current vaccine measures. Here, we
characterized BA. 2.86 and the XBB-lineage variant FLip by investigating their neutralization …
