Mechanism of action

The quadrivalent HPV vaccine contains virus-like particles (VLPs) derived from the major capsid protein of four HPV types. When administered, these VLPs trigger a humoral immune response that generates neutralizing antibodies against these HPV types, preventing viral infection of epithelial cells and reducing the risk of HPV-related cancers and genital warts.
