Mechanism of action

The vaccine contains inactivated H1N1 influenza virus antigen combined with AS03, an oil-in-water adjuvant containing squalene, alpha-tocopherol, and polysorbate 80. The adjuvant enhances and accelerates the body's immune response to the viral antigen, promoting both humoral (antibody) and cellular immunity against H1N1 influenza. This formulation allows for dose-sparing while maintaining immunogenicity.
