An open, phase IV, multicentre study to assess the long-term persistence of antibodies against hepatitis B and the immune response to a hepatitis B vaccine challenge in healthy children 7 to 9 years old, previously vaccinated with 4 doses of GlaxoSmithKline (GSK) Biologicals’ DTPa-HBV-IPV/Hib vaccine or 4 doses of GSK Biologicals’ HBV vaccine, in clinical trials conducted by GSK Biologicals. - DTPa-HBV-IPV-110

• Conditions: Four dose vaccination course with GSK Biologicals’ DTPa-HBV-IPV/Hib vaccine or with GSK Biologicals’ HBV vaccine, given as a three dose primary vaccination series in the first year of life, followed by a booster in the second year of life: immune persistence and hepatitis B vaccine challenge at 7 to 9 years of age.
