Primary Outcome Measures:
  • protective level of anti HBs antibodies [ Time Frame: 1 month after the last does of vaccine ] [ Designated as safety issue: No ]

    Antibody titer >10 IU/ml 30 days following last vaccine dose will be considered protective.

    In the work done by Altunoz et al., titer rate below 10 IU was observed in 40% of the patients, while 40% of the patients achieved a rate of above 100 IU. Therefore, we can estimate that the geometric mean of distribution is approx. 50 IU. A sample size of 37 patients in each group achieves a power of 80% to detect a ratio above 1.37 between the two vaccinated groups.

Estimated Enrollment: 75

Estimated Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
