Gardasil 9 is a new vaccine that protects against nine human papillomavirus (HPV) types, the same four types in Gardasil plus five additional types with cancer causing potential.
Protection against HPV types 31, 33, 45, 52, and 58 in Gardasil 9 can prevent 20 percent more cervical, vulvar, and vaginal cancers than the Gardasil vaccine. Both Gardasil 9 and Gardasil protect against the potential cancer causing HPV types 16 and 18 and against genital warts caused by HPV types 6 and 11. Oral and anal cancers in men and women as well as cervical, vulvar, and vaginal cancers in women have been linked to infection with HPV types 16 and 18.
Gardasil 9 is currently only approved for use in the U.S.
