No. A 3-dose Comvax series is a complete Hepatitis B series AND a Hib series, as long as the minimum ages and minimum intervals for the individual antigens are observed. Comvax contains PedvaxHIB, which is a 2-dose primary series followed by a booster dose after 12 months of age. If any other brand of Hib is used for the primary series (either of the first two doses), then the child will need a total of 4 Hib doses.
