National, Regional, State, and Selected Local Area Vaccination Coverage Among Adolescents Aged 13-17 Years — United States, 2014

784 MMWR / July 31, 2015 / Vol. 64 / No. 29 Routine immunization is recommended for adolescents aged 11–12 years by the Advisory Committee on Immunization Practices (ACIP) for protection against diseases including pertussis, meningococcal disease, and human papillomavirus (HPV)–associated cancers (1). To assess vaccination coverage among adolescents, CDC analyzed data collected regarding 20,827 adolescents through the 2014 National Immunization Survey–Teen (NIS-Teen).* From 2013 to 2014, coverage among adolescents aged 13–17 years increased for all routinely recommended vaccines: from 84.7% to 87.6% for ≥1 tetanusdiphtheria-acellular pertussis (Tdap) vaccine dose, from 76.6% to 79.3% for ≥1 meningococcal conjugate (MenACWY) vaccine dose, from 56.7% to 60.0% and from 33.6% to 41.7% for ≥1 HPV vaccine dose among females and males, respectively.† Coverage differed by state and local area. Despite overall progress in vaccination coverage among adolescents, HPV vaccination coverage continues to lag behind Tdap and MenACWY coverage at state and national levels. Seven public health jurisdictions achieved significant increases in ≥1or ≥3-dose HPV vaccination coverage among females in 2014, demonstrating that substantial improvement in HPV vaccination coverage is feasible. NIS-Teen monitors vaccination coverage among adolescents aged 13–17 years in the 50 states, District of Columbia (DC), selected local areas, and territories§ using a random-digit– dialed sample of landline and cell phone numbers.¶ NIS-Teen occurs in two phases: 1) a telephone interview with an adolescent’s parent or guardian, during which sociodemographic and vaccination provider contact information is collected and, after receiving consent, 2) a mailed questionnaire to identified vaccination providers to obtain immunization information from medical records.** Coverage estimates are based on providerreported vaccination histories for adolescents with adequate provider data. In 2014, national estimates included information from 20,827 adolescents (10,084 females and 10,743 males).†† Details regarding NIS-Teen methodology, including methods for weighting and synthesizing provider-reported vaccination National, Regional, State, and Selected Local Area Vaccination Coverage Among Adolescents Aged 13–17 Years — United States, 2014
