Eligibility Criteria
-----------------
Inclusion Criteria: A male or female ≥ 15 years of age at the time of the first vaccination. Free of obvious health problems as established by medical history and clinical examination before entering into the study. Written informed consent obtained from the subject/ from the parents or guardians of the subject. Known to be seronegative for anti-HBs-antibodies, anti-HBc-antibodies and/or HBsAg. Positive for the HLA-DQ2 genotype as determined in the previous sero-HBV-069 prevalence study. If the subject is female, she must be of non-childbearing potential, or, if of childbearing potential, she must be abstinent or use adequate contraceptive precautions for one month prior to enrollment and up to two months after the last vaccination Exclusion Criteria: Use of any investigational or non-registered drug or vaccine other than the study vaccine(s) during the study period or within 30 days preceding the first dose of study vaccine. Planned administration/ administration of a vaccine not foreseen by the study protocol during the period starting from 30 days before each dose of vaccine and ending 30 days after. Previous vaccination against hepatitis B. History of non-response to previous hepatitis B vaccination. Known exposure to hepatitis B within 6 weeks. History of hepatitis B infection. Confirmed human immunodeficiency virus (HIV) infection. A family history of congenital or hereditary immunodeficiency. History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. Acute disease at the time of enrollment. Hepatomegaly, right upper quadrant abdominal pain or tenderness. Administration of immunoglobulins and/or any blood products within the three months preceding the first dose of study vaccine or planned administration/ administration during the study period.
