|Treatments||dtap-ipv-hep b-prp-t combined vaccine (hexaxim™)|
|Sponsor||Sanofi Pasteur, a Sanofi Company|
|Collaborator||National Institute of Hygiene and Epidemiology, Vietnam|
|Start date||April 2015|
|End date||September 2016|
|Trial size||354 participants|
|Trial identifier||NCT02428491, A3L35, NCT02821195, U1111-1143-8177|
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.
- 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
- To evaluate the immunogenicity of the study vaccine one month after the third dose primary series.
- 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 describe the persistence of all antibodies before receipt of the booster vaccination.
