This study compared the long-term persistence of anti-hepatitis A (anti-HAV) and B (anti-HBs) antibodies, 5 years after vaccination of subjects aged 1-11 years with a combined hepatitis A and B vaccine either in a two-dose (0, 6 months, Adult formulation) or a three-dose (0, 1, 6 months, Paediatric formulation) schedule. At the end of the 5 years, all subjects (100%) in both groups continued to have anti-HAV antibodies > or =15mIU/mL, while 94-97% of subjects in both groups had anti-HBs antibody concentrations > or =10mIU/mL. Subjects with anti-HBs antibody concentration < or =10mIU/mL were administered a challenge dose of hepatitis B vaccine. All subjects mounted a vigorous immune response ..View full abstract
