Trial overview
Official title: Assess long-term persistence of hepatitis B antibodies & immune response to a hepatitis B vaccine (Engerix-B Kinder) challenge in children aged 4-5 years (previously primed & boosted in the 1st 2 years of life with DTPa-HBV-IPV/Hib vaccine)
Trial description: The purpose of this study is to determine at 5 years of age the persistence of immunity to hepatitis B that was conferred by infant vaccination with Infanrix hexa™.The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
