PROBLEM: The Ebola virus disease crisis in West Africa revealed critical weaknesses in health policy and systems in the region, including the poor development and retention of policy leaders able to set sound policy to improve health. Innovative models for enhancing the capabilities of emerging leaders while retaining their talent in their countries are vital. APPROACH: Chatham House (London, United Kingdom) established the West African Global Health Leaders Fellowship to help develop the next generation of West African public health leaders. The innovative program took a unique approach: Six weeks of intensive practical leadership and policy training in London and Geneva bookended a 10-month policy project conceived and carried out by each fellow in their home country. The program emphasized practice, site visits and observation of U.K. public health organizations, identifying resources, and networking. Strong mentorship throughout the fieldwork was a central focus. Work on the pilot phase began in June 2016; the fellows completed their program in September 2017. OUTCOMES: The pilot phase of the fellowship was successful, demonstrating that this "sandwich" model for fellowships-whereby participants receive focused leadership training at the start and end of the program, minimally disrupting their lives in-country-offers exciting possibilities for enhancing leadership skills while retaining talent within Africa. NEXT STEPS: On the basis of this successful pilot, a second cohort of eight fellows began the program in October 2018. The expanded African Public Health Leaders Fellowship has become a central activity of Chatham House's Centre on Global Health Security.
