Mechanism of action

The vaccine contains a prefusion-stabilized form of the RSV F protein (PreF3), which is a key surface antigen that triggers neutralizing antibodies and cellular immunity. The adjuvant component enhances the immunogenicity of the vaccine by activating innate immune responses. This combination aims to provide robust protection against RSV disease, particularly in older adults and other high-risk populations.
