The current COVID-19 monovalent vaccine continues to work against new and evolving virus variants, according to a new report from the World Health Organization (WHO) Advisory Technical Board on COVID-19 Vaccine Composition.

The advisory board meets twice a year to discuss the ongoing efficacy of the COVID-19 vaccine and determine whether any changes are needed in the vaccine’s makeup.
