Hepatitis B Hepatitis A | Biological: Twinrix™ Adult Biological: Twinrix™ Junior | Phase 3 |
Open, randomized, long-term antibody persistence studies. Immune persistence was compared between subjects who received one of the two formulations of GlaxoSmithKline Biologicals' combined hepatitis A and hepatitis B vaccine according to a two-dose or three-dose schedule. These long-term follow-up studies involved taking blood samples at approximately 6, 7, 8, 9 and 10 years after the primary vaccination of combined hepatitis A and B vaccine, to assess antibody persistence and a retrospective safety follow-up.
The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

- Number of Subjects With Anti-hepatitis A Virus (HAV) Antibody Concentrations Above the Cut-off Value [ Time Frame: Year 6, 7, 8, 9 and 10 after the first vaccine dose of a two-dose or three-dose primary vaccination ]Anti-HAV antibody concentration cut-off value assessed was ≥ 15 milli-International Units per milliliter (mIU/mL).
- Number of Subjects With Anti-Hepatitis B Surface Antigen (HBs) Antibody Concentrations Above the Cut-Off Value [ Time Frame: Year 6, 7, 8, 9 and 10 after the first vaccine dose of a two-dose or three-dose primary vaccination ]Anti-HBs antibody concentration cut-off value assessed was ≥ 3.3 mIU/mL.
- Serious Adverse Events (SAE) Causally Related to Primary Vaccination or Related to Hepatitis A or B Infection or Related to Study Participation (Blood Sampling) [ Time Frame: From Year 6 through to Year 10 ]
An SAE is any untoward medical occurrence that:
results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/ incapacity, is a congenital anomaly/birth defect in the offspring of a study subject, or may evolve into one of the outcomes listed above.
