Keen on teen vaccines: improvement of adolescent vaccine coverage in rural North Carolina.
To improve adolescent immunization coverage in a rural North Carolina county.Adolescent immunization coverage rates in an intervention and four comparison counties were compared over 1 year. We introduced practice-based interventions in seven practices centering on immunization registry-driven recall of adolescents for immunizations with postcard reminders (Phase 1), and 6 months later employed nontargeted school-generated telephone reminders to parents of adolescents (Phase 2).Improvements in the intervention county among 11- to 12-year-olds occurred for first-dose human papillomavirus vaccine in both boys (overall change, 14.2%-32.1%) and girls (27.4%-43.4%) and the meningococcal vaccine (34.6%-49.4%). Improvements among adolescents 13-18 years were limited to human papillomavirus vaccine completion in boys (1.6%-4.2%). Improvements were greater during Phase 1 than Phase 2 and among younger adolescents. Coverage improvements in the comparison counties were smaller than those observed in the intervention county.A resource-light two-phase intervention led to modest improvements in immunization coverage, most notably in the largest adolescent practice in the county, and suggested potential for further gains, particularly among younger adolescents.
