Anti-Hep B Antibodies at Age 12 to 18 Months After Hep B Vaccine at Birth and DTaP-IPV-Hep B-PRP-T Hexavalent Vaccine Concomitantly With Prevnar® at 2, 4 and 6 Months of Age
Persistence of Anti-Hep B Antibodies at 12 to 18 Months of Age in Children Having Received Hep B Vaccine at Birth and a DTaP-IPV-HB-Hib Hexavalent Vaccine (Hexaxim® or Infanrix Hexa®) Concomitantly With Prevnar® at 2, 4 and 6 Months of Age
Primary Objective:
To describe the persistence of Hep B antibodies (Ab) at 12 to 18 months of age following a three-dose infant primary series vaccination of either Hexaxim®/Hexyon®/Hexacima® or Infanrix® hexa at 2, 4 and 6 months of age following Hep B vaccination at birth.
