HPV vaccination

HPV vaccines protect against important types of human papillomavirus. They work best before someone encounters these virus types. They are intended to help prevent infections and, later, some cancers and warts. They do not treat an existing HPV infection or an abnormal cervical screening result. Eligibility and the number of doses depend on the local vaccination programme, age and any relevant medical circumstances.

  • HPV vaccination aims to prevent infection with certain HPV types. This helps reduce the risk of conditions including cervical cancer, anal cancer, some mouth and throat cancers, and genital warts.
  • The vaccine works best before exposure to the virus. That is why vaccination is often offered at a young age, before many people become sexually active.
  • The vaccine prevents disease; it does not treat it. It does not treat an existing infection, a positive HPV test or warts or abnormal cells that are already present.
  • The schedule varies with age, vaccine type and local guidance. Follow your own region's programme rather than isolated advice online.
  • Screening remains important after vaccination when locally recommended, because the vaccine does not protect against every HPV type.
