- Abstract
The article reports that the SARS-CoV-2 Omicron BA.5 sublineage accounted for most of the sequenced viral genomes in the U.S., with further Omicron sublineage diversification through November 2022. It mentions that the VISION Network evaluated vaccine effectiveness (VE) of a bivalent mRNA booster dose as compared with no previous vaccination and previous receipt of 2, 3, or 4 monovalent-only mRNA vaccine doses.
