HPV is very common in the United States — at any given time, about 1 in 4 people have it. Most HPV infections go away on their own, but some last longer — and they can cause cancer or other health problems, like genital warts. The good news is that the HPV vaccine is very effective at preventing cancer and many other health problems caused by the virus. Frequently Asked Questions Why is the HPV vaccine important? HPV infections are so common that nearly all men and women get at least 1 type of HPV at some point in their lives — and the complications can be serious. About 25,000 17,500 women and 20,000 9,300 men get cancer caused by HPV infections in the United States every year. Many of these cancers don’t cause symptoms until they’ve gotten serious and hard to treat. Getting vaccinated against HPV can protect your child from HPV infections that cause cancer. What is HPV? HPV is a group of more than 150 viruses. Many people who get HPV have no symptoms. Some people who get HPV develop warts in their genital area. Some HPV infections don’t go away and can cause cancer, including: Cervical cancer Cancer inside the vagina (vaginal cancer) or outside the vagina (vulvar cancer) Cancer of the penis (penile cancer) Cancer of the anus (anal cancer) or rectum (rectal cancer) Cancer of the throat (oropharyngeal cancer), including the base of the tongue and tonsils HPV spreads through intimate skin-to-skin contact. Most of the time, it spreads when a person who has an HPV infection has vaginal, oral, or anal sex. And since HPV may not cause symptoms, people can have it — and spread it to others — without knowing. Learn more about HPV. Who needs to get the HPV vaccine?
