The human papillomavirus (HPV) vaccine helps protect against infection by the strains of HPV that are most likely to cause the following:
These disorders are caused by the human papillomavirus, which also causes genital warts.

There are three vaccines for HPV:
All three HPV vaccines protect against the two types of HPV (types 16 and 18) that cause about 70% of cervical cancers and 90% of anal cancers. The nine-valent vaccine and quadrivalent vaccine protect against the two types of HPV (types 6 and 11) that cause more than 90% of genital warts, in addition to protecting against types 16 and 18. Only the nine-valent vaccine and quadrivalent vaccine are recommended for boys and men.
Only the nine-valent vaccine is currently available in the United States.
The HPV vaccine is given as an injection into a muscle in a 2-dose or a 3-dose series. If the initial dose of the HPV vaccination is given at age 9 to 14 years, a 2-dose series is given. If the initial dose of the HPV vaccination is given at age 15 years or older, a 3-dose series is given (see routine childhood vaccination).
