Exclusion Criteria

• •1. Serum HBsAg-positive just before inclusion in the clinical trial.
• •2. Serum HBeAg-positive within 3 months before transplantation.
• •3. Serum HBV DNA-positive by standard DNA hybridisation assay (lower detection limit 105 genomes/ml), or by any less sensitivity technique, within 3 months before transplantation.
• •4. Unknown serum HBV replication status (no data about HbeAg and HBV DNA) within 3 months before transplantation.
• •5. Previous recurrence of HBV in the transplanted liver defined by serum HBV DNA- positive by sensitive hybridisation (lower detection limit 105 genomes/ml) assay or any less sensitive technique, and/or serum HBeAg-positive, and/or serum HBsAg-positive.
• •6. Re-transplanted liver even for reasons not related to HBV infection.
• •7. Evidence of hepatocellular carcinoma in the transplanted liver, or metastatic disease, at time of inclusion in the clinical trial.
• •8. Evidence of graft rejection at time of inclusion in the clinical trial.
• •9. Life-expectancy less than 1 year.
• •10. VHC infection.
• •11. HIV type 1 or type 2 infection.
• •12. Acute HAV infection.
• •13. Previous treatment with i.m. HBIG Grifols within 3 months before inclusion in the clinical trial.
• •14. Intolerance or allergy to any i.m. HBIG Grifols containing substance (glycine, sodium chloride, sterile water for injection, homologous human immune globulin).
• •15. History of SAEs related to the administration of human blood-derived products.
• •16. History of frequent AEs, even non-serious, related to the administration of human blood-derived products.

• •26. Any severe acute or chronic medical, surgical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration, or may interfere with the interpretation of study results and, in the judgment of the investigator, makes the subject inappropriate for entry in this clinical trial.
• •27. Impossibility to donate a serum sample before the first investigational product administration.
• •28. Planned treatment with Ig other than i.m. HBIG Grifols within the clinical trial period.
