The HPV vaccine protects preteens, teens, and young adults from Human Papillomavirus (HPV). Research shows that when boys and girls are vaccinated early - at 11 or 12 - they're better protected from the serious health problems HPV can cause, including certain cancers and genital warts.
There are two HPV vaccines: Gardasil and Cervarix. Gardasil, which protects against four HPV types (6, 11, 16, and 18), is approved by the FDA for use by females aged 9-26 to help prevent cancer of the cervix, vagina, and vulva; genital warts, and anal cancer. It's also approved for males aged 9-26 to help prevent genital warts and anal cancer.
