Is it appropriate to administer Hib-Hep B (Comvax) at 2 and 6 months to an infant who had hepatitis B vaccine at birth?
No, you are depriving the child of the dose of Hib at 4 months of age. It is important to give the Hib at 4 months of age because one dose at 2 months does not offer adequate protection and very young children are the ones at greatest risk for Hib disease. If the child received a birth dose of hepatitis B vaccine and you are using Comvax, then give Comvax at 2 and 4 months of age with a final dose at 12-15 months of age. Don’t delay the schedule and deny the child the complete benefit of the Hib component.
