What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
protective level of anti HBs antibodies
Time Frame: 1 month after the last does of vaccine

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.
