Hib-containing vaccine is recommended in a 4-dose schedule for infants at 2, 4, 6 and 18 months of age.

Infants can have their 1st dose as early as 6 weeks of age. If the 1st dose is given at 6 weeks of age, infants should still receive their next scheduled doses at 4 months and 6 months of age.

The vaccines usually received at each schedule point are:

  • 2, 4 and 6 months of age — (DTPa-hepB-IPV-Hib diphtheria-tetanus-acellular pertussis, hepatitis B, inactivated poliovirus, Hib)
  • 18 months of age — monovalent Hib

The recommended number of doses and intervals for catch-up Hib vaccines vary with the child’s age. For catch-up recommendations, see Table. Catch-up schedule for Haemophilus influenzae type b (Hib) vaccination for children <5 years of age in Catch-up vaccination.
