Active clinical trials for "Hepatitis B"

To compare three formulations of Hib-MenAC vaccines mixed with Tritanrix™-HepB vaccine with that of Tritanrix™-HepB vaccine concomitantly administered with GSK Biologicals' Hiberix™ vaccine and Tritanrix™-HepB vaccine mixed with Hiberix™ vaccine and concomitantly administered with Wyeth Lederle's meningococcal C conjugate vaccine (Meningitec™), with respect to antibody response to vaccine antigens (meningococcal serogroups A and C and PRP) after a three-dose primary vaccination course.

The aim of this study is to evaluate the long-term persistence of hepatitis A and B antibodies at Years 11, 12, 13, 14 and 15 years after subjects received their first dose of a 3 dose vaccination schedule of combined hepatitis A/hepatitis B vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007. This protocol posting deals with objectives & outcome measures of the extension phase at year 11 to 15.

The purpose of this study is to determine if treatment with intramuscular hepatitis B virus immune globulin Grifols, a new specific hepatitis B immune globulin, is effective and safe for the prevention of hepatitis B virus recurrence after orthotopic liver transplantation.

This study will assess the immunogenicity and safety of the GlaxoSmithKline (GSK) Biologicals' (formerly SmithKline Beecham Biologicals') combined DTPa-HBV-IPV/Hib (Infanrix hexa™) vaccine administered in the 3rd, 5th, 11th month of life. The last dose of DTPa-HBV-IPV/Hib will be given simultaneously with one dose of OPV vaccine.

To evaluate the persistence of anti-hepatitis A virus (HAV) and anti-hepatitis B surface antigen (HBs) antibodies up to 2, 3, 4 and 5 years after administration of the first dose of the study vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

The purpose of this study is to evaluate the persistence of anti-hepatitis B surface antigen (anti-HBs) antibodies 16, 17, 18, 19 and 20 years after administration of the first dose of the study vaccine. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

This study is performed to evaluate the persistence of anti-hepatitis B surface antigen (HBs) antibodies up to 16, 17, 18, 19 and 20 years after administration of the first dose of the study vaccine, Engerix-B™. No new subjects will be recruited in this long-term follow-up study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.

To compare the two formulations of GSK Biologicals' DTPw-HBV vaccine to concomitant administration of CSL's DTPw vaccine and GSK Biologicals' HBV with respect to the antibody response to the diphtheria antigen after a three-dose primary vaccination course.

The purpose of this study is to evaluate the safety of administering a combination vaccine (DTaP-HepB-IPV; Pediarix™) to infants at birth, 2 and 6 months compared to the administration of a HepB vaccine at birth and the same combination vaccine at 2, 4, and 6 months of age. Additionally, researchers will assess the body's antibody response (proteins produced by the body's immune system that help fight infections) following each vaccine dose. The study will enroll 5 healthy newborns, ages 0-5 days. Participants will be involved in study related procedures for up to 288 days, including blood sample collection and 5 study visits.

To determine the efficacy of a hepatitis vaccine in preventing hepatitis B.
