Immunogenicity and Safety of Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T Combined Vaccine Given at 6, 10 and 14 Weeks of Age in Infants From India Who Previously Received a Dose of Hepatitis B Vaccine at Birth
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.

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 — 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 — 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.
