- Proof that child has received a full 3-dose regimen of licensed Hepatitis B vaccine in infancy.
Exclusion criteria:
- Acute disease at the time of enrolment.
- Serious acute or chronic illness determined by clinical or physical examination and laboratory screening tests.
- Laboratory screening tests for haemoglobin, total white cell count, platelets, ALT and creatinine out of acceptable limits.
- Planned administration/administration of a vaccine (not in the scope of the study) within 30 days of the first dose of vaccine(s) with the exception of tetanus toxoid or scheduled Yellow fever or Measles vaccine.
- Use of any investigational or non-registered drug or vaccine other than the study vaccines within 30 days preceding the first dose of the study vaccine, or planned use during the study period.
- Administration of immunoglobulins, blood transfusions or other blood products within the three months preceding the first dose of study vaccine or planned administration during the study period.
- Chronic administration of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
- Simultaneous participation in any other clinical trial;
- Previous participation in any other malaria vaccine trial;
- Any twins
- History of allergic reactions (significant IgE-mediated events) or anaphylaxis to previous immunizations.
- History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
- Any other findings that the investigator feels would increase the risk of having an adverse outcome from participation in the trial.
