Celiac disease and infection with hepatitis B virus (HBV) are very prevalent worldwide and carry a high morbidity rate. It has been recently shown that patients with celiac disease very often fail to develop immunity after standard vaccination for HBV during infancy. In this study, we will evaluate whether a second vaccination series with a different vaccine, Sci-B-Vac, results in a better immunological response in celiac patients. Eligible patients will be randomized to receive a 3-dose vaccination series with Engerix or Sci-B-Vac vaccines.. Rate of responders and level of immunity will be compared. This study will facilitate better protection of celiac patients to this potentially deadly virus.

Primary Outcome Measures:
  • Comparison of the geometric mean titers of anti-HBs between the Engerix B group and the Sci-B-Vac group [ Time Frame: two years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Rate of responders four weeks after the completion of the series [ Time Frame: two years ] [ Designated as safety issue: Yes ]
  • Rate and characteristics of adverse drug reactions [ Time Frame: two years ] [ Designated as safety issue: Yes ]
  • Numerical increase in the antibodies titer before and after vaccination [ Time Frame: two years ] [ Designated as safety issue: Yes ]
  • Rate of responders in the cross over phase. [ Time Frame: two years ] [ Designated as safety issue: Yes ]
  • Association between the HBsAg-specific cytokine secreting PBMCs by the ELISPOT assay and vaccine response [ Time Frame: two years ] [ Designated as safety issue: No ]
  • Association between genetic make-up and vaccine response [ Time Frame: two years ] [ Designated as safety issue: No ]
