研究概览
简要总结
The focus of this study is to evaluate how risk factors like age, gender, body mass index, smoking, alcohol consumption, etc. can influence immune response when subjects are vaccinated with GSK Biologicals' combined hepatitis A/hepatitis B vaccine or monovalent hepatitis A and B vaccines (from GSK Biologicals' or different manufacturers). The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
详细描述
The study will also evaluate the persistence of hepatitis A and hepatitis B antibodies at months 12, 24 and 36 after the first dose of primary vaccination course.

结局指标
主要结局
Number of Subjects With Anti-HAV and Anti-HBs Antibody Concentrations Above the Cut-off Value
时间窗: At Month 7
Seropositivity for anti-HAV antibodies was defined as anti-HAV antibody concentration ≥ 15mIU/mL; seropositivity for anti-HBs antibodies was defined as anti-HBs antibody concentration ≥ 3.3 mIU/mL.
Number of Seroprotected Subjects Against Hepatitis B Surface (HBs) Antigen
时间窗: At Month 7
A seroprotected subject was defined as a vaccinated subject with a serum anti-HBs antibody concentration equal to or above (≥) 10 mIU/mL.
Antibody Concentrations for Anti-hepatitis A Virus (Anti-HAV) and Anti-hepatitis B Surface (Anti-HBs) Antigens
时间窗: At Month 7 after Twinrix vaccination
Anti-HAV and anti-HBs antibody concentrations are presented as geometric mean concentrations (GMCs), expressed in milli International Units per milliliter (mIU/mL). The reference seropositivity cut-off values for anti-HAV and anti-HBs antibodies were equal to or above (≥) 15 mIU/mL and ≥ 3.3 mIU/mL, respectively.
