Why does my child need HPV vaccine?
HPV vaccine is important because it protects against cancers caused by human papillomavirus (HPV) infection. HPV is a very common virus; nearly 80 million people—about one in four—are currently infected in the United States. About 14 million people, including teens, become infected with HPV each year.
Most people with HPV never develop symptoms or health problems. Most HPV infections (9 out of 10) go away by themselves within two years. But, sometimes, HPV infections will last longer, and can cause certain cancers and other diseases. HPV infection can cause:
- cancers of the cervix, vagina, and vulva in women;
- cancers of the penis in men; and
- cancers of the anus and back of the throat, including the base of the tongue and tonsils (oropharynx), in both women and men.
Every year in the United States, HPV causes 33,700 cancers in men and women. HPV vaccination can prevent most of the cancers (about 31,200) from ever developing.
