Brief Summary:
The objective is to assess the efficacy of Hepatitis B Virus vaccination in a population of IBD patients treated with immunosuppressive medications.

Arm Intervention/treatment
Experimental: ENGERIX-B Biological: ENGERIX-B (HBV Vaccine)
ENGERIX-B (Hepatitis B Vaccine) 20 mcg, A series of 3 doses (1 mL each) given on a 0-, 1-, 6-month schedule.
Other Name: ENGERIX-B

Experimental: Sci-B-Vac Biological: Sci-B-Vac
Sci-B-Vac (Hepatitis B Vaccine) 10 μg/ml, A series of 3 doses (1 mL each) given on a 0-, 1-, 6-month schedule.

Primary Outcome Measures :
  1. 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.
