Overview
Brief Summary
The purpose of this study is to describe the immunogenicity and safety of a novel DTaP- IPV- Hep B-PRT~T fully liquid combined hexavalent vaccine (Hexaxim™) administered at 6, 10 and 14 weeks of age in infants born to mothers documented to be serum anti-hepatitis B surface antigen (HBsAg) serology negative in India.
Primary Objective:
- To evaluate the immunogenicity of the study vaccine in terms of seroprotection [diphtheria toxoid, tetanus toxoid, poliovirus types 1, 2 and 3, Haemophilus influenzae type b (Hib) polysaccharide (PRP), hepatitis B (Hep B)] and vaccine response for pertussis antigens [pertussis toxoid (PT) and filamentous haemagglutinin (FHA)] one month after the third dose.
Secondary Objectives:
- To further describe the immunogenicity of the study vaccine, before the first dose and one month after the third dose.
- To describe the safety after each and any doses of the study vaccine.
Detailed Description
All participants will receive a total 4 doses of Hep B, i.e. one dose of Hep B monovalent vaccine given at birth followed by 3 doses of Sanofi Pasteur's hexavalent vaccine given at 6, 10 and 14 weeks of age in the context of the study. Participants and parents will attend four clinic visits; the expected participation in the study is approximately 3 months.

Outcomes
Primary Outcomes
Percentage of Participants With Seroprotection After Vaccinations With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine Following a Documented Dose of a Commercial Oral Poliovirus Vaccine and Recombinant Hep B Monovalent Vaccine at Birth
Time Frame: Pre-dose 1 to one month post-dose 3
Diphtheria antibodies were measured by a toxin neutralization test, tetanus antibodies by an enzyme-linked immunosorbent assay (ELISA), Haemophilus influenzae type b polysaccharide (PRP) antibodies by Farr type radioimmunoassay, poliovirus 1, 2, and 3 antibodies by a neutralization assay, and Hepatitis B (Hep B) antibodies were measured by VITROS ECi/ECiQ Immunodiagnostic System. Description of seroprotection: Diphtheria and Tetanus antibody concentrations ≥0.01 International Units (IU)/mL; Poliovirus 1, 2, and 3 titers ≥8 (1/dilution); Hep B concentrations ≥10 mIU/mL, and PRP ≥0.15 µg/mL.
Percentage of Participants With Vaccine Response After Vaccinations With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine Following a Documented Dose of a Commercial Oral Poliovirus Vaccine and Recombinant Hep B Monovalent Vaccine at Birth
Time Frame: Pre-dose 1 to one month post-dose 3
Anti-pertussis toxin (PT) and anti-filamentous hemagglutinin (FHA) antibodies were measured with an ELISA. Vaccine response was defined as percentage of participants with post-dose 3 anti-PT and anti-FHA antibody concentrations in ELISA units (EU)/mL ≥ 4 x Lower Limit of Quantification (LLOQ) if pre-vaccination concentration was \< 4 x LLOQ or ≥ pre-vaccination concentration if pre-vaccination concentrations ≥ 4 x LLOQ.

- Percentage of Participants With Seroprotection Before and After Vaccinations With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine Following a Documented Dose of a Commercial Oral Poliovirus Vaccine and Recombinant Hep B Monovalent Vaccine at Birth(Pre-dose 1 to one month post-dose 3)
- Geometric Mean Titers of Antibodies Against Vaccine Antigens After Vaccinations With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine After a Documented Dose of an Oral Poliovirus Vaccine and Recombinant Hep B Monovalent Vaccine at Birth(Pre-dose 1 to one month post-dose 3)
- Percentage of Participants Reporting Solicited Injection-site or Systemic Reaction After Each Vaccination With Sanofi Pasteur's DTaP-IPV-HB-PRP-T Combined Vaccine Following a Documented Dose of Oral Poliovirus and Recombinant Hep B Vaccine at Birth(Within 7 days after each vaccine injection)
