Outcome Measures

Primary Outcomes (1)

  • protective level of anti HBs antibodies

    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.
