A Study to Compare the Immune Response and Safety Elicited by Henogen's Adjuvanted Hepatitis B Vaccine Compared to GSK Biologicals Adjuvanted Hepatitis B Vaccine in Pre-Dialysis and Dialysis Patients Who Have Not Been Exposed to Hepatitis B.

Study participants will receive either Henogen's adjuvanted hepatitis B vaccine or GSK Biologicals' adjuvanted hepatitis B vaccine. The study involves a total of 7 visits and blood samples will taken at each of these visits.

Inclusion criteria

• Use of any investigational or non-registered drug or vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period.
• Use of any registered vaccine within 7 days before the first dose of study vaccine.
• Previous vaccination against hepatitis B (whether or not the subject responded to the vaccine).
• History of hepatitis B infection.
• Known exposure to hepatitis B virus within 6 months.
• Use of immunoglobulins within six months preceding the first study vaccination.
• Immunosuppression caused by the administration of parenteral steroids or chemotherapy (oral steroids are allowed).
• Any confirmed or suspected 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 vaccines.

• Oral/axillary temperature superior or equal to 37.5°C (or 37 °C in Czech Republic).
• Pregnant or lactating female
