  • * Children were considered UTD with vaccination when they had received at least 4 DTaP/DTP vaccines, 3 poliovirus vaccines, 1 MMR vaccine, 3 Haemophilus influenza vaccines and 3 hepatitis B vaccines at the time the interview was conducted.

  • Percentage UTD and OR in comparison with reference group is weighted; significant ORs (P < .05) shown in bold.

  • Asked only of insured children. OR indicates odds ratio; CI, confidence interval; DTaP, diphtheria-tetanus-acellular pertussis; DTP, diphtheria-tetanus-pertussis, MMR, measles-mumps-rubella.
