Immunogenicity Study of DTaP-IPV-Hep B-PRP~T Combined Vaccine in Comparison to Infanrix®Hexa, at 2-4-6 Months of Age in Healthy Peruvian Infants
The study aims to confirm that, in Peruvian infants, the investigational DTaP-IPV Hep B-PRP\~T vaccine has immunological and safety profiles that are comparable to those of the control vaccine that is already marketed (Infanrix®Hexa) Primary Objective: To demonstrate that the hexavalent DTaP-IPV-Hep B-PRP\~T combined vaccine induces an immune response that is at least as good as the response following Infanrix®Hexa in terms of seroprotection rates to HB, one month after a three-dose primary series (2, 4 and 6 months) Secondary Objectives: * To describe in each group the immunogenicity to vaccine components (for DTaP-IPV-Hep B-PRP\~T and Infanrix®Hexa) one month after the third dose of the primary series. * To assess the overall safety in each group one month after each dose of the primary series and through the entire study.

- Hepatitis B
Interventions
- DTaP IPV HB PRP~T vaccine
- DTaP-HB-IPV and Haemophilus influenzae type b
Primary outcomes
- Number of Participants Achieving Seroprotection for Anti Hep-B After a Primary Series of Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™ — Day 150 (1 month after dose 3)
Anti-hepatitis B (Hep B) antibodies were measured by chemiluminescence detection. Seroprotection was defined as a titer ≥ 10 mIU/mL. - Number of Participants Achieving Seroprotection to Vaccine Antigens After a Primary Series Vaccination With Either DTaP-IPV-Hep B-PRP~T or Infanrix Hexa™ Vaccine. — Day 150 (1 month after dose 3)
Antibody titers were measured by chemiluminescence detection for hepatitis B (Hep B), by Farr type radioimmunoassay for Haemophilus influenzae type b (PRP), and by toxin neutralization test for diphtheria. Seroprotection criteria were defined as: Criteria 1: Anti-Hep B titer ≥ 10 mIU/mL; Anti-PRP titer ≥ 0.15 µg/mL; Anti-diphtheria titer ≥ 0.01 IU/mL. Criteria 2: Anti-Hep B titer ≥ 100 mIU/mL; Anti-PRP titer ≥ 1 µg/mL; Anti-diphtheria titer or ≥ 0.1 IU/mL.
