This book examines the failures exposed by COVID-19 and lays out a practical plan to reduce the risk of future pandemics through better preparation and global cooperation: improved surveillance and early-warning systems, fast diagnostics and contact tracing, expanded vaccine and therapeutic research and manufacturing capacity, stronger health systems and workforce training in low-income countries, and coordinated funding and governance to ensure equitable access to tools. It argues for investing now in technologies, supply chains, and routine rehearsal of outbreak responses so the world can move quickly from detection to containment, rather than repeatedly reacting after the fact.
