New COVID boosters providing more protection against variants
Body
The new bivalent booster vaccine provides better protection against newly emerged Omicron sublianeages than previous monovalent COVID vaccines, according to new research from the University of Texas Medical Branch. Researchers also found that three of the new sublineages, BA.2.75.2, BQ.1.1, and XBB.1, exhibit the greatest evasion against vaccine-elicited neutralization and may become the new dominant strains.
