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

Outcome Measures
Primary Outcomes (1)
The antibody titers for each valence of DTaP-IPV-Hep B-PRP-T vaccine (except poliovirus) post-primary and booster vaccination.
Age 3.5 and 4.5 years after infant and booster vaccination
Study Arms (3)
Group 1
Participants previously received 3 doses and a booster dose of the investigational vaccine DTaP IPV Hep B PRP-T.
Group 2
Participants previously received 3 doses CombAct-Hib™ + Engerix™ B + OPV and a booster dose of CombAct-Hib™ + Oral poliovirus vaccine (OPV) vaccine.
Group 3
Participants previously received 3 doses DTaP IPV Hep B PRP-T; a dose of Engerix™ B at birth, and a booster dose of DTaP IPV Hep B PRP-T vaccine.
Eligibility Criteria
Participants aged 3 years and a half on the day of inclusion and must have received the primary series of vaccinations and a booster vaccination in Study A3L15 (NCT 00362336). No vaccination will be provided or administered in this study.
You may qualify if:
- Informed consent form signed by a parent or other legally acceptable representative and by an independent witness if the parent or other legal guardian is illiterate.
- Subject and parent/ legally acceptable representative able to attend the scheduled visits and to comply with all trial procedures.
- Receipt of primary vaccination with 3 doses of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™ + Oral poliovirus vaccine (OPV) + Engerix™ B and a booster dose of either DTaP-IPV-Hep B-PRP-T or CombAct-Hib™+ OPV.
You may not qualify if:
- Incomplete primary and booster immunization at trial A3L15.
- Previous confirmed clinical, serological, or microbiological diagnosis of diphtheria, tetanus, whooping cough, poliomyelitis, Haemophilus influenza b or hepatitis B after completion of A3L15 Study.
- Subjects known to have received diphtheria, tetanus, pertussis, Haemophilus influenza b and hepatitis B vaccination after completion of A3L15 Study.
- Known or suspected congenital or acquired immunodeficiency since completion of A3L15 Study.
- Serious chronic illness occurring after receipt of the primary and booster series (e.g. leukemia, lymphoma \[Tor B cells\], Crohn's disease).
- Known or suspected subject seroconversion for human immunodeficiency virus (HIV) or hepatitis C seropositivity since completion of A3L15 Study.
