Mechanism of action

The vaccine contains inactivated (killed) influenza virus antigens representing two influenza A subtypes (H1N1 and H3N2) and two influenza B lineages. It works by presenting these antigens to the immune system to generate humoral and cellular immune responses, producing antibodies and T-cell immunity against the targeted influenza strains. The non-adjuvanted formulation relies on the inherent immunogenicity of the viral antigens without additional immune-enhancing compounds.
