Biostatistics & Data Management

Our Biostatistics & Data Management team conducts data management, statistical analyses, and transmission modeling of infectious diseases, which supports IVI’s field research.

For example, in 2014, the team helped the Dengue Vaccine Initiative (DVI) launch a mobile-based system using PDA devices and conduct data management training using internet applications at a field site in Burkina Faso during the peak of the Ebola virus crisis in West Africa. The use of internet applications in data management was a new approach and helped avoid delay of the study launch due to travel restrictions to Burkina Faso and political instability as a result of the Ebola crisis. This real-time data collection system using tablet devices is also being planned for IVI’s typhoid surveillance studies in Africa.

IVI, in collaboration with WHO’s Global Vaccine Safety Initiative (GVSI), developed a new software tool for collecting and processing information on adverse events following immunization (AEFI).
Known as the Vaccine Adverse Events Information Management System (VAEIMS), this tool was pilot-tested in Sri Lanka and evaluated for its ability to transfer AEFI data from health outposts into a central database for processing and conversion of raw data to information for action. Based on its success, Sri Lanka has decided to use it at the national level. VAEIMS will soon be adapted for global use.
