Definition

A vaccine that is no longer available in the United States but is still used in other countries to protect against infection with four types of human papillomavirus (HPV). Gardasil is used in females and males aged 9 to 26 years to protect against low-risk HPV types 6 and 11, which cause most genital warts, and against high-risk HPV types 16 and 18, which cause most precancerous lesions and cancers of the cervix, vagina, vulva, and anus. Gardasil may also prevent HPV-related cancers of the penis and oropharynx. Also called recombinant human papillomavirus quadrivalent vaccine.
