Consistency of 3 Consecutive Lots of a Novel HBV Vaccine With Single-blind Safety Evaluation Using Engerix™-B as Control

Study Overview
=================
Brief Summary
-----------------
The purpose of the present study is to evaluate the immunogenicity and safety of three consecutive production lots of the novel adjuvanted HBV vaccine. The safety of the candidate vaccine will be assessed using Engerix™-B as control.

Detailed Description
-----------------
Double-blind for the identity of the consistency lots, single-blind for the control group/study vaccine identity. At the time of conduct of this study, the sponsor GlaxoSmithKline was known by its former name SmithKline Beecham

If the subject is female, she must be of non-childbearing potential, or, if of childbearing potential, she must be abstinent or have used adequate contraceptive precautions for 30 days prior to vaccination, have a negative pregnancy test and must agree to continue such precautions for two months after completion of the vaccination series. Exclusion Criteria: Use of any investigational or non-registered drug or vaccine other than the study vaccine(s) within 30 days preceding the first dose of study vaccine, or planned use during the study period. Planned administration/Administration of a vaccine not foreseen by the study protocol within 30 days of the first dose of vaccine(s). Previous vaccination against hepatitis B History of non-response to previous hepatitis B vaccination Known exposure to hepatitis B within the previous 6 weeks History of hepatitis B infection Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection. A family history of congenital or hereditary immunodeficiency. Suspected or confirmed multiple sclerosis in the subject (applicable to Centre 5/France only) History of allergic disease or reactions likely to be exacerbated by any component of the vaccine. Acute disease at the time of enrolment. 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 during the study period. Pregnant or lactating female
