Brief Summary:

The aim of the study is to assess the persistence of anti-Hep B antibody at 9 to 10 years of age after the last priming dose in subjects who completed study A3L12 (NCT00401531), and also evaluate the immune response against hepatitis B one month after vaccination (challenge vaccination) with a stand alone monovalent hepatitis B vaccine.

Primary objectives:

  • To describe the persistence of anti-hepatitis B antibody at 9 to 10 years of age after last priming dose in subjects having received hepatitis B vaccine at birth and a hexavalent vaccine at 2, 4 and 6 months of age according to the vaccine received during A3L12 study (Hexaxim® [Group 1] or Infanrix® hexa [Group 2])
  • To evaluate the immune response against hepatitis B one month after vaccination with a stand alone monovalent hepatitis B vaccine (challenge vaccination).

Secondary objectives:

  • To describe serious adverse events (SAEs) reported throughout the trial after administration of hepatitis B vaccine.

Condition or disease Intervention/treatment Phase
Hepatitis B Biological: Euvax B®: Hepatitis B vaccine Phase 3

Detailed Description:
Subjects age 9 to 10 years who had received 3 injections of Hexaxim® or Infanrix® hexa and have completed the A3L12 study will be invited to participate in this study. They will receive one dose of Euvax-B® vaccine at Day 0.

  • Assent form signed by subject
  • Subject and parent(s)/legally acceptable representatives able to attend the scheduled visits and to comply with all trial procedures
  • Receipt of primary vaccination with 3 doses of either Hexaxim® or Infanrix® hexa at the age of 2, 4, and 6 months in the A3L12 study, and hepatitis B vaccine at birth.

Exclusion Criteria:

  • Participation in another clinical trial investigating a vaccine, drug, medical device, or a medical procedure in the 4 weeks preceding the inclusion in the trial
