Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States. Studies showed a consistent association between HPV and cervical cancer in the 1990s. HPV is transmitted by direct contact, usually sexual, with an infected person. Transmission occurs frequently with sexual intercourse but can occur following non-penetrative sexual activity. Most of the time, HPV has no symptoms so people do not know they have it. In addition to cervical cancer, the virus causes anal and penile cancer, and genital warts.

Protection against HPV can be prevented through vaccination. Currently there are two vaccines that are licensed in the United States; HPV4 (Gardasil) and HPV2 (Cervarix). Both vaccines are recommended for females starting at 11 years but can be given through 26 years of age. HPV4 vaccine is recommended for males starting at age 11 years but it can be given through 21 years of age (26 years if high risk for HPV). HPV2 is not approved for males. With both vaccines, more than 99% of recipients develop an antibody response to HPV types included in the respective vaccines 1 month after completing the 3 dose series. 

Ideally, vaccines should be administered before potential exposure to HPV through sexual contact; however, females who may already have been exposed to HPV should be vaccinated if in recommended age groups. Both HPV vaccines require 3 doses to complete the series. The second and third doses should be administered 2 and 6 months after the first dose. There should be at least 24 weeks between the first and the third HPV doses.
