Case scenario: Does a baby need an additional Hep B dose at 6 months after previous doses of combination vaccines?

Q: If a  baby had received hexaxim at 6 week followed by pentavac pfs at 10weeks and  14 weeks. Should we still give her HepB vaccine for the 6th month dosage?

Hepatitis B vaccination is recommended as 3 doses only. Timeline of the doses depends on the type of vaccine used. If it is a monovalent vaccine with only Hepatitis in it is given at Birth dose followed by a monovalent 2nd dose at 6 weeks ,then a monovalent  3rd dose can be given at 6 months of age (2nd and 3rd dose can be monovalent/pentavalent combination also).

Alternatively if the baby has received  the combination vaccines which includes Hep B during 3 primary doses of combination vaccines ( pentavalent-pentavac pfs and /or  hexavalent-hexaxim),  given at 6, 10 and 14 weeks after birth dose (monovalent), then no further vaccination is  required for Hepatitis B as the immune response of the baby is already primed with the given doses.
