Study Details

Study Description

Brief Summary

The purpose of this study is to describe the immunogenicity and safety of Sanofi Pasteur's DTaP-IPV-Hep B-PRP-T fully liquid combined hexavalent vaccine (Hexaxim®) administered at 2, 3, and 4 months of age and at 16 to 17 months of age in infants and toddlers who received a dose of Hep B vaccine at birth or within 1 week after birth.

Primary Objective:

To describe the safety profile after each and all doses of Sanofi-Pasteur's DTaP-IPV-Hep B-PRP-T combined vaccine in Vietnamese infants and toddlers.

Secondary Objective:

To demonstrate the non-inferiority of the immune response to all antigens induced by the study vaccine in Vietnamese infants one month after the third dose in a 3-dose primary series with the immune response to all antigens induced by the same study vaccine outside Vietnam.
To evaluate the immunogenicity of the study vaccine one month after the 3-dose primary series.
To describe the persistence of all antibodies before receipt of the booster vaccination.
To evaluate the immunogenicity of the study vaccine one month after the booster.

Detailed Description

Participants will receive a total of 5 doses of Hep B: One dose of Hep B monovalent vaccine given at birth or within 1 week after birth followed by 3 doses of the Sanofi Pasteur's hexavalent vaccine given as primary series at 2, 3, and 4 months of age and then a booster dose at 16 to 17 months of age, to comply with Vietnamese vaccination recommendations.

Intervention Model Description:

Participants in this trial were randomized in a 1:1 ratio in 2 cohorts. All participants in both cohorts received Sanofi Pasteur's DTaP-IPV-HB-PRP~T combined vaccine in a 3-dose Infant Series. Participants from Cohort 1 provided blood samples for immunogenicity assessment and were evaluated for safety and immunogenicity. Participants in Cohort 2 did not provide any blood samples for immunogenicity analysis and were evaluated for safety only.Participants in this trial were randomized in a 1:1 ratio in 2 cohorts.
