Abstract: Despite strong scientific evidence, many health innovations fail to achieve sustained impact at scale. This seminar examines why the challenge of translating evidence into action is fundamentally a systems and leadership problem. Drawing on comparative case studies from across Africa and recent empirical work on vaccine scale-up and pandemic response, the talk explores how leadership, trust, integration, and coordination shape real-world outcomes. Using examples from routine immunization, digital health, and COVID-19 vaccine delivery, the seminar highlights why evidence alone is insufficient and what enables health systems to scale innovations under both routine and crisis conditions.
