Human Papillomavirus Infection

Human papillomaviruses (HPVs) can cause a variety of medical conditions. Many HPVs are sexually transmitted, and some can lead to cancer of the cervix, anus, and throat. Two HPV vaccines are licensed in the United States, one protecting against four strains of HPV, and the other protecting against two. HPV vaccination is recommended in the United States for adolescents. More
