研究概览
简要总结
This is a study to evaluate the immune response and safety of GSK Biologicals 2-dose inactivated hepatitis A vaccine when administered with a diphtheria, tetanus and pertussis combination (DTaP) vaccine and a Haemophilus influenza type B (Hib) vaccine in children 15 months of age. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
详细描述
An open, controlled comparison of Havrix™ administered alone or with Infanrix™ and ActHIB. The three groups evaluated are: 1) Havrix™ alone, 2) Havrix™ + Infanrix™ and ActHIB and 3) Infanrix™ and ActHIB followed by Havrix™ one month later.

- •Planned administration or administration of any vaccine not foreseen by the study protocol during the period 42 days before and 31 days after each dose of study vaccine(s).
- •Previous vaccination against DTaP using a commercially-available brand other than Infanrix™ or Pediarix™ or against Hib using a commercially-available brand other than ActHIB™, HibTITER™ or OmniHIB™.
- •Previous vaccination with more than three doses of DTaP-containing vaccines or more than three doses of Hib-containing vaccines.
- •Previous vaccination against hepatitis A,
- •History or known exposure to hepatitis A,
- •History of diphtheria, tetanus, pertussis and/or Haemophilus influenza type b,
- •Known exposure to diphtheria, tetanus, pertussis and/or Haemophilus influenza type b within 31 days prior to the start of the study,
- •History of non-response to any vaccine in the current routine immunization schedule,
- •Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection,
- •A family history of congenital, hereditary or infectious immunodeficiency or parental risk factors for HIV infection,
- •History of allergic disease/reactions or hypersensitivity likely to be exacerbated by any component of Havrix™, Infanrix™ or ActHIB™ including 2-phenoxyethanol, neomycin and gelatin,
- •History of hypersensitivity/allergic reaction to latex
- •Major congenital defects or serious chronic illness,
- •History of any neurologic disorder
- •Acute disease at the time of vaccination.
- •Administration of immunoglobulins and/or any blood products within three months prior to the first dose of study vaccine or planned administration at any time during the entire study period, i.e., the Enrolment Phase, the Active Phase and the Extended Safety Follow-up Phase

结局指标
主要结局
Number of Seropositive Subjects for Anti-hepatitis A Virus (HAV) Antibodies Following the Second Dose of Havrix
时间窗: 31 days following the second dose of Havrix™
Subjects are defined as being anti-HAV seropositive if their anti-HAV antibody concentration is ≥ 15 milli-International Units per milliliter (mIU/mL).
