Gardasil has been shown to also be effective in preventing genital warts in males.[12][13] On 9 September 2009, an advisory panel recommended that the FDA licence Gardasil in the United States for boys and men ages 9–26 for the prevention of genital warts.[14] Soon after that, the vaccine was approved by the FDA for use in males aged 9 to 26 for prevention of genital warts[12][13] and anal cancer.[15] While Gardasil and Gardasil-9 vaccines have been approved for males, the third HPV vaccine, Cervarix, is not administered to males. Unlike the Gardasil-based vaccines, Cervarix does not protect against genital warts.[16]
