What is Gardasil 9?

Gardasil 9 is a vaccine approved by the U.S. Food and Drug Administration (FDA) for use in people 9 through 45 years of age to protect against the following diseases caused by certain types of human papillomavirus (HPV):

  • Cervical cancer
  • Vulvar and vaginal cancers
  • Anal cancer
  • Certain head and neck cancers, such as throat and back of mouth cancers
  • Genital warts
  • Precancerous cervical, vaginal, vulvar, and anal lesions

HPV infection is a risk factor for the development of the diseases listed above. HPV infection can be an opportunistic infection (OI) of HIV. An OI is an infection that occurs more frequently or is more severe in people with weakened immune systems—such as people with HIV—than in people with healthy immune systems. To learn more about OIs, read the HIVinfo What is an Opportunistic Infection? fact sheet.

The Guidelines for the Prevention and Treatment of Opportunistic Infections in Adults and Adolescents with HIV and the Guidelines for the Prevention and Treatment of Opportunistic Infections in Children with and Exposed to HIV includes recommendations on the use of Gardasil 9 in people living with HIV.
