Mechanism of action

Bivalent vaccines are formulated to contain antigens from two different pathogens or two variants of the same pathogen, enabling the immune system to generate protective antibodies and cellular responses against both targets in a single vaccination. This approach is commonly used for influenza (seasonal strains) and COVID-19 (original strain plus variant) vaccines to broaden immunological coverage.
