Gardasil is a quadrivalent HPV vaccine that targets HPV 16 and 18 which cause all cervical cancer as well as HPV 6 and 11 which cause 90% of genital warts. It is most effective prior to sexual debut. The Advisory Committee on Immunization Practices recommends that HPV vaccination be offered to women between age 11-12 as well as catch-up vaccination for women 13-26. It should not be offered to pregnant women because of teratogenicity noted in clinical trials. The vaccine has also been FDA-approved for use in men, and a clinical trial showed decreased anal intraepithelial neoplasia and cancer in men who have sex with men. Lastly, women who receive the HPV vaccine prior to sexual debut do not need to have cervical screening until age 25.
