Concomitant HPV and MenACWY vaccination among sixth and seventh graders receiving Tdap.
OBJECTIVE: To describe use of human papilloma virus (HPV) and meningococcal (MenACWY) vaccines among sixth and seventh grade Kansas children receiving their school-required tetanus, diphtheria, and acellular pertussis (Tdap) booster.
METHODS: We used Medicaid and commercial claims data in Kansas from 2013, 2014, and 2015 to identify HPV and MenACWY vaccinations among sixth and seventh graders receiving a Tdap booster. Rates of concomitant vaccinations were calculated at the state and county level, and logistic regression was used to identify predictors of concomitant vaccination.
RESULTS: Of sixth and seventh graders in Kansas receiving their required Tdap booster, 53-82% failed to receive a concomitant HPV vaccine and 36-47% failed to receive a concomitant MenACWY vaccine from 2013 to 2015. Rates of concomitant vaccinations varied more than four-fold across counties. Female gender, younger age, and Medicaid (versus commercial insurance) were positively associated with concomitant vaccination; concomitant vaccination rates increased from 2013 to 2015 (p < 0.001). Of children continuously enrolled in Medicaid from 2013 to 2015, who did not receive concomitant vaccination in 2013, 72.3% and 68.6% remained unvaccinated against HPV and MenACWY, respectively by the end of 2015.
CONCLUSIONS: Failure to get a concomitant vaccination at the time of their Tdap booster identifies children at high risk of not getting immunized in the ensuing 2-3 years. 'Back to school' programs focusing only on school-required vaccinations could have negative impacts on overall vaccination rates. Tracking rates of concomitant vaccination might be useful in supporting quality assessment and improvement efforts.
