Human papillomavirus (HPV) is a very common infection that can be passed from person to person. Some types of HPV are spread through sexual contact. Sexually transmitted HPV can spread through vaginal, oral, or anal sex. Studies suggest that at least three out of every four people who have sex will get a genital HPV infection at some time during their lives. To lower your risk of infection, limit your number of sexual partners and use condoms.
Some types of HPV cause cancer of the cervix. This type of cancer develops over a long period of time. HPV causes cells on or around the cervix to become abnormal. In some cases, these cells may progress to precancerous.
A vaccine is available that protects you against the two types of HPV that cause the most cases of cervical cancer and the two types of HPV that cause the most cases of genital warts. The vaccine triggers a woman's immune system to fight off these viruses if she is exposed to them.
The vaccine is given in three doses over a six-month period. It is most effective when administered to girls and women before they become sexually active. The vaccine is approved for use by girls and women between 9 and 26 years of age and is recommended as a routine vaccination for all girls aged 11 to 12 years.
