A Study to Assess the Anamnestic Immune Response in Healthy 4 to 7 Year-old Children After a Primary Vaccination Series With Either HEXAVAC® or INFANRIX®-HEXA
An Open-label, Randomised, Controlled, Multi-centre Study of the Immunogenicity and Safety of a Booster Dose of Two Different Hepatitis B Vaccines to Explore the Anamnestic Immune Response in Healthy 4 to 7 Year-old Children Previously Vaccinated at About 3, 5 and 11 to 13 Months of Age With Either HEXAVAC® or INFANRIX®-HEXA
Primary objective:
- To describe in subjects vaccinated with 3 doses of HEXAVAC® or 3 doses of INFANRIX®-HEXA during the first two years of life the percentage of subjects with an anti-HBs antibody titre ≥10 mIU/mL 1 month after a booster dose of either HBVaxPRO® 5 µg or Engerix B® 10 µg .
Secondary objectives:
- Additional immunogenicity assessments
- Standard safety assessment.
