The bivalent COVID-19 vaccines include a component of the original virus strain to provide broad protection against COVID-19 and a component of the omicron variant to provide better protection against COVID-19 caused by the omicron variant. These are called bivalent COVID-19 vaccines because they contain these two components. A bivalent COVID-19 vaccine may also be referred to as “updated” COVID-19 vaccine booster dose.

COVID-19 vaccines can help protect against severe illness, hospitalization and death from COVID-19. As the virus changes and your immunity naturally decreases over time, you may lose some of that protection.
