A key role of obstetrician/gynecologists and other healthcare providers is to provide patients and their parents with information on the benefits and safety of the HPV vaccine, and to encourage adolescents to receive this vaccine. The American College of Obstetricians and Gynecologists (ACOG) updated its 2014 recommendations to include the new 9-valent HPV vaccine, also recommended by CDC for girls and boys aged 11 to 12 years. Those who do not receive the HPV vaccine during the target age range should undergo catch-up vaccination until age 26 years.
