Ifedayo Adetifa FWACP (Paeds) MSc PhD

Assistant Professor /Clinical Epidemiologist


I obtained a Fellowship of the West Africa Collge of Physicians in Paediatrics in 2005, a MSc in Epidemiology from the School in 2009 and a PhD from the University of Amsterdam in 2012. Before joining the School, I worked as a Research Clinician and later as Clinical Epidemiologist at the Medical Research Unit-The Gambia. My research interests and work at the MRCG were in TB Epidemiology. I joined the School in June 2014 and I am based overseas at the KEMRI-Wellcome Trust Research Programme where I conduct vaccine impact studies.




I am a Distance Learning tutor for Basic Statistics with Computing (EPM101) and Study Design: Writing a grant (EPM201) modules of the MSc Epidemiology and I organise and teach on the Vaccines session on the DTMH course at the school. In addition, I teach on the Postgraduate Diploma in Research Methods course at the KEMRI-Wellcome Trust Research Programme/Pwani University, Kilifi, in Kenya


My research interests are Infectious diseases epidemiology specifically vaccine impact studies including assessments of indirect and non-specific effects of vaccines; assessments of crude and effective vaccine coverage, serological surveys of population immunity and innovative approached to increasing vaccine coverage. However, I still retain interest in TB Epidemiology- active/enhanced case finding in populations.

I work as co-principal investigator and co-investigator respectively on the following vaccine effectiveness studies in Kenya-Pneumococcal Conjugate Vaccine Impact Study (PCVIS) and the Rotavirus Immunisation Programme Evaluation in Kenya (RIPEK)
