加卫苗,（亦作Gardasil、Gardisil、Silgard、recombinant human papillomavirus vaccine [types 6, 11, 16, 18]），是人类乳突病毒疫苗的一种，用于预防特定毒株的人类乳突病毒（HPV），特别是6，11，16和18型。约70%的子宫颈癌，以及大多数的肛门癌、外阴癌、阴道癌和阴茎癌由16和18型HPV病毒感染造成。约90%的尖锐湿疣病例由6型和11型的HPV病毒感染引起。尽管加卫苗不能清除体内已经存在的病毒，仍然推荐HPV阳性患者接种，因为疫苗可以使患者免受其他种类毒株的感染。加卫苗所预防的毒株都是通过性行为传播的。加卫苗在2006年6月8日由美国食药监局认可。至2008年，美国41个州也相继认可了该疫苗。除美国外，还有120个国家认可加卫苗。美国食药监局建议青春期前及无性行为经验的人群接种该疫苗。

Gardasil, also known as Gardisil or Silgard or recombinant human papillomavirus vaccine [types 6, 11, 16, 18], is a vaccine for use in the prevention of certain strains of human papillomavirus (HPV), specifically HPV types 6, 11, 16 and 18. HPV types 16 and 18 cause an estimated 70% of cervical cancers, and are responsible for most HPV-induced anal, vulvar, vaginal, and penile cancer cases. HPV types 6 and 11 cause an estimated 90% of genital warts cases. Though it does not treat existing infection, vaccination is still recommended for HPV positive individuals, as it may protect against one or more different strains of the disease. The HPV strains that Gardasil protects against are sexually transmitted. It was approved in the US on June 8, 2006 by the U.S. Food and Drug Administration (FDA). In 2008, Gardasil was approved in 41 of U.S. states. The Gardasil vaccine has also been approved in 120 other countries. The FDA recommends vaccination before adolescence and potential sexual activity.
