Research

Dr Mackenzie has co-ordinated surveillance for pneumococcal disease and carriage evaluating the clinical and economic effectiveness of the introduction of pneumococcal conjugate vaccine in The Gambia. He is currently conducting a large cluster-randomised trial of different pneumococcal vaccine schedules.

His other work has investigated long-term outcomes after childhood hospital admissions and the critical role of malnutrition, epidemiology, aetiology and risk factors for childhood pneumonia, the changing performance over time of IMCI criteria for pneumonia, causes of serious bacterial illness and interactions with malaria epidemiology, and the epidemiology of acute respiratory viral disease in children.
