Primary Outcome Measures:
  • Number of Anti-hepatitis B Surface Antigen (Anti-HBs) Seroprotected Subjects [ Time Frame: At Months 30, 42, 54 & 66 ] [ Designated as safety issue: No ]

    The number of seroprotected subjects (i.e. with anti-HBs antibody concentrations ≥ 10 mIU/ml) is given for each respective follow-up timepoint.

    The total number of subjects analysed (N) is given for both groups between brackets in the category titles.

Secondary Outcome Measures:
  • Occurrence of Serious Adverse Events Determined by the Investigators to Have a Causal Relationship to Vaccination or to Study Procedures [ Time Frame: At Months 30, 42, 54 & 66 ] [ Designated as safety issue: Yes ]

Enrollment: 267
Study Start Date: April 2004
Study Completion Date: January 2008
Primary Completion Date: January 2008 (Final data collection date for primary outcome measure)
