Concomitant Vaccines Among Youth Receiving Tdap

Vaccine; ePub 2018 Sep 25; Doke, Fitzgerald, et al

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, a recent study found. Furthermore, “back to school” programs focusing only on school-required vaccinations could have negative impacts on overall vaccination rates. Researchers used Medicaid and commercial claims data in Kansas from 2013, 2014, and 2015 to identify human papillomavirus (HPV) and meningococcal (MenACWY) vaccinations among 6th and 7th graders receiving a Tdap booster. They found:

  • Of 6th and 7th 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 >4-fold across counties.
  • Female gender, younger age, and Medicaid (vs commercial insurance) were positively associated with concomitant vaccination; concomitant vaccination rates increased from 2013 to 2015.
  • 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.
