Last month new booster vaccines made by Moderna and Pfizer became available. They are called "bivalent," because they protect against currently circulating Omicron variants as well as earlier strains of the SARS-CoV-2 virus that causes COVID-19. Boosters reduce the likelihood of becoming infected with Omicron, and they also reduce the likelihood of hospitalization and death should one become infected despite vaccination.
