XBB.1.5 vaccine booster shows promise against new Omicron variants in latest study

A study posted to bioRxiv reveals that the monovalent XBB.1.5 vaccine booster significantly boosts neutralizing antibodies against new SARS-CoV-2 Omicron sub-variants. The research shows that both XBB.1.5 vaccination and infection elevate neutralizing titers, with the vaccine being particularly effective in infection-naïve individuals and those previously infected with Omicron.
