Brief Summary

The purpose of this study is to evaluate the long term immunogenicity produced in children by the investigational hexavalent vaccine (DTaP-IPV-Hep B-PRP-T) given in Study A3L15 (NCT 00362336).

Primary Objective: To describe the antibody long term persistence at 3.5 and 4.5 years of age following a 3 dose primary series vaccination of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + Oral poliovirus vaccine (OPV) + Engerix™ B vaccination at 6, 10 and 14 weeks of age and a booster vaccination of DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + OPV at 15-18 months

Detailed Description

All participants must have received the primary series of vaccinations and a booster vaccination in Study A3L15 (NCT 00362336).
