NCT00358332

Brief Summary

The purpose of this study is to test the safety and dosages of a malaria vaccine in 100 children, 1-6 years old, in Bandiagara, Mali. The study is testing the safety of the vaccine when it is given to people who are regularly exposed to malaria and it will provide information regarding optimal vaccine dosage. This study will compare 3 injections of different vaccine doses to a rabies vaccine that is already approved. During the study, the child's health will be checked in the clinic and during home visits. Children may participate for about 14 months, and blood will be taken from each child throughout the study. If the child becomes sick from malaria, he/she will be treated. Information from this study may be used to develop a malaria vaccine that will help control the disease.

Outcome Measures

Primary Outcomes (4)

  • Occurrence of Solicited Systemic Symptoms During a 7-day Surveillance Period (Systematically Collected) Following Vaccinations at Days 0, 30, and 60.

    The number of participants reporting drowsiness irritability/fussiness, loss of appetite, vomiting, and feverishness. Participants are counted only once but may have experienced symptoms on multiple occasions.

    7 Days following any vaccination

  • Occurrence of Unsolicited Symptoms During a 30-day Surveillance Period Following Vaccinations at Days 0, 30, and 60.

    The number of participants spontaneously reporting any symptom (defined as any Adverse Event considered associated with the product) within 30 days of any vaccination. Participants are counted only once but may have experienced events on multiple occasions.

    Day of vaccination and 30 subsequent days.

  • Number of Subjects Spontaneously Reporting Any Serious Adverse Event.

    Any untoward medical occurrence that resulted in death, persistent/significant disability/incapacity, required in-patient hospitalization or prolongation thereof, was life threatening or a congenital anomaly/birth defect in offspring of a study subject; or may have jeopardized the participant or required intervention to prevent one of the outcomes.

    1 year after the last vaccination.

  • Occurrence of Solicited Local Symptoms During a 7-day Surveillance Period (Systematically Collected) Following Vaccinations at Days 0, 30, and 60.

    The number of participants reporting pain, swelling and erythema. Participants are counted only once but may have experienced symptoms on multiple occasions.

    7 Days following any vaccination
