Immunizing Adolescents to Prevent Cancers

Human papillomavirus (HPV) is a common virus that can lead to cancer. About one in four people are currently infected with HPV in the United States and approximately 14 million people, including teens, become infected with HPV each year.¹ In many cases the HPV infection goes away on its own, but when it does not the HPV may cause cancer in some people.

• HPV is known to cause cancers in the following locations: cervix, vagina, vulva, penis, anus, rectum and oropharynx (back of the throat including the base of the tongue and tonsils).
• Approximately 33,700 new cases of cancer in the U.S. each year are caused by HPV. Of these cancers, about 20,260 were among women and 13,477 among men.²
• Current HPV vaccines prevent over 90% of all HPV-related cancers from happening.³

Tracking Progress

MaineHealth pediatric and family medicine practices have substantially increased their up-to-date rates for HPV vaccine.

• As of October 2018, 59% of adolescents cared for at MaineHealth practices were up-to-date on the full HPV vaccine series (2+doses) by their thirteenth birthday. Just one year earlier, only 54% of adolescents were up-to-date.
• Among the highest performing practices, MaineHealth Stephens Hospital achieved a 73% up-to-date rate and MaineHealth Medical Group fully immunized 63% of 13-year-olds.
