Convergent evolution of SARS-CoV-2 Omicron subvariants leading to the emergence of BQ.1.1 variant

Jumpei Ito et al.

Summary: This study evaluates the importance of 5 mutations and characterizes the virological properties of variant BQ.1.1. Younger Omicron lineages are found to be more likely to acquire these mutations, which increase viral fitness. BQ.1.1 variant evades BA.2 and BA.5 infections more efficiently and exhibits lower pathogenicity in hamsters compared to BA.5. This study provides insights into the convergent evolution of known Omicron lineages as of 2022.

Omicron escapes the majority of existing SARS-CoV-2 neutralizing antibodies

Yunlong Cao et al.

Summary: The Omicron variant of SARS-CoV-2 contains 15 mutations in the receptor-binding domain, leading to evasion of over 85% of tested neutralizing antibodies. Different epitope groups of neutralizing antibodies are affected to varying degrees by single mutations of Omicron. Antibodies targeting the conserved region of sarbecovirus remain most effective against Omicron.
