To determine vaccination coverage at selected ages and by birth cohort and to assess whether all indicated vaccines were administered during vaccination visits.
Population-based cross-sectional study.
National Immunization Survey–Teen 2009 telephone interview.
United States adolescents aged 13 to 17 years with provider-reported vaccination histories (N = 20 066).
Main Outcome Measures
Among all adolescents and by birth cohort: coverage estimates for 3 childhood vaccines (measles-containing, hepatitis B, and varicella) and 3 adolescent vaccines (tetanus-diphtheria and/or tetanus-diphtheria-acellular pertussis, meningococcal-containing, and human papillomavirus for girls) at selected ages.
By age 11 years, most adolescents had obtained the childhood vaccines. Receipt of a tetanus-diphtheria and/or tetanus-diphtheria-acellular pertussis vaccine at ages 11 to 12 years increased significantly from the 1991 to 1996 birth cohort (33.8% vs 68.2%, P < .001); receipt of meningococcal-containing vaccine at ages 11 to 12 years increased significantly from the 1993 to 1996 birth cohort (8.4% vs 50.0%, P < .001). Among girls, receipt of human papillomavirus vaccine at ages 11 to 12 years increased significantly from the 1994 to 1996 birth cohort (11.1% vs 30.5%, P < .001). Overall, 54.9% of adolescents received at least 1 vaccination visit at ages 11 to 12 years. Among adolescents who made a vaccination visit at ages 11 to 12 years and were eligible for vaccination, 19.5% did not receive tetanus-diphtheria and/or tetanus-diphtheria-acellular pertussis, 60.9% did not receive meningococcal-containing, and 62.4% did not receive human papillomavirus vaccines.
Receipt of vaccines at the recommended ages of 11 to 12 years appears to be increasing; however, providers often do not administer all indicated vaccines during a vaccination visit.
