The HPV vaccine you are getting is one of two vaccines that can be given to prevent HPV. It may be given to both males and females. This vaccine can prevent most cases of cervical cancer in females, if it is given before exposure to the virus. In addition, it can prevent vaginal and vulvar cancer in females, and genital warts and anal cancer in both males and females. Protection from HPV vaccine is expected to be long-lasting.
The quadrivalent HPV vaccine is a new vaccine; additional data will be available in the near future from clinical trials. These data and any new information on epidemiology of HPV will be reviewed by ACIP as they become available, and recommendations will be updated as needed.fficacy of HPV Vaccine in Men: Studies are needed to define the efficacy of HPV vaccination in preventing genital warts and anogenital intraepithelial neoplasia in men. Studies of the effectiveness of HPV vaccination of men in preventing transmission to both female and male sex partners are also needed.
