Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

DTaP-HB-PRP\~T combined vaccine is being developed in order to comply with expanding programs for immunization in infancy, while offering the benefit of a reduced number of injections, and potentially of an increased acceptance.

Primary Objectives:

* To describe the antibody persistence at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP\~T or Tritanrix-Hep B/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hepatitis B (Hep B) vaccine given at birth.
* To describe the effect of a booster dose of DTaP-HB-PRP\~T on immunogenicity at 12 to 18 months following a three-dose primary series vaccination of either DTaP-HB-PRP\~T or Tritanrix HepB/Hib™ given at 6, 10 and 14 weeks of age, and one dose of Hep B vaccine given at birth.

Secondary Objective:

* To describe the safety profile of the booster dose of the DTaP-HB-PRP\~T vaccine when administered concomitantly with Oral Polio Vaccine (OPV).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will assess the immunogenicity and reactogenicity of the investigational DTaP-HB-PRP\~T combined vaccine when given as a booster dose, concomitantly with OPV, in Filipino children previously primed at 6, 10, and 14 weeks with the investigational DTaP-HB-PRP\~T combined vaccine or Tritanrix-Hep B/Hib™ vaccine and having received a first dose of Hep B vaccine (Recomvax B™) at birth in a previous study, AL201 (NCT00348881).

Exclusion Criteria

* Participation in another clinical trial in the 4 weeks preceding the trial vaccination
