Human papillomma virus vaccine
Gardasil is used to prevent genital warts and cervical/vaginal/anal cancers caused by human papillomavirus (HPV) types 6, 11, 16, and 18 in girls and young women ages 9 through 26. Gardasil is also used to prevent genital warts caused by HPV types 6 and 11 in boys and young men ages 9 through 26. Human papillomavirus (HPV) can cause genital warts, cancer of the cervix, and various cancers of the vulva or vagina.
Mechanism of effect
Human beings develop a humoral immune response to the vaccine, although the exact mechanism of protection is unknown
Pharmacodynamic
HPV only infects human beings. Animal studies with analogous animal papillomaviruses suggest that the efficacy of L1 VLP vaccines may involve the development of humoral immune responses
