In the context of recent events, including public response to interventions to tackle the COVID-19 pandemic, vaccination uptake and the use of health data and digital health, this important book uses empirical evidence to address why public trust is vital to a well-functioning health system. In doing so, it provides a comprehensive contemporary explanation of public trust, how it affects health systems and how it can be nurtured and maintained as an integral component of health system governance.
