If a child received a primary series with TriHIBit and another dose of TriHIBit at 18 months of age, does the child need another dose of Hib?
This is difficult to answer because there are really no data. The Hib doses given for the primary series are invalid since TriHIBit was used. TriHIBit should not be used for the booster dose unless the child has received at least one prior dose of Hib. Since the prior doses were invalid, the booster dose is technically invalid. Therefore, a valid booster dose of single antigen Hib should be given.
