Only Two Doses of HPV Vaccine Needed for Younger Adolescents

October 20, 2016

Human papillomavirus vaccination series completion will now require only two doses of vaccine for adolescents younger than 15 years. The Advisory Committee on Immunization Practices approved this recommendation at their biannual meeting in Atlanta yesterday. The new schedule for <15 year olds calls for the second dose to be given between 6 and 12 months after the first dose. Adolescents receiving the first dose of HPV vaccine at age 15 or older will continue to be recommended three doses of vaccine, given at 0, 1-2, and 6 months.
