Human papillomavirus (HPV) is a very common infection spread through intimate skin-to-skin contact. Most infections clear on their own, but some types can lead to genital warts or to cancers of the cervix, throat, anus, penis, vagina or vulva.
- The vaccine protects against the HPV types most often linked to these cancers and warts.
- It works best when given before any exposure to the virus, so it is usually offered to preteens and young teens of all genders.
- Catch-up vaccination may be available for older teens and young adults, depending on local guidelines.
- Side effects are usually mild, such as a sore arm.
Vaccination does not replace cervical screening, so people with a cervix should still attend screening when invited. Ask your doctor or nurse about the right schedule for you or your child.
