Clinical Trial: Epidemiology Study of Malaria Transmission Intensity in Africa
Study Status: Completed
Recruit Status: Completed
Study Type: Observational
Official Title: Epidemiology Study of Malaria Transmission Intensity in Sub-Saharan Africa
Brief Summary: The aim of this epidemiology study is to characterize in a standardized way malaria transmission intensity at the clinical trial centers participating in study 110021 (NCT00866619).
Detailed Summary:
This study is a multicenter epidemiology study at centers that are participating in GSK's pivotal Phase III candidate malaria vaccine 110021 ( NCT00866619) trial and will involve 4 annual cross sectional surveys performed preferably at peak transmission.
There will be no study vaccine administered in this epidemiology study.
