‘ This book tells the story of how vaccines transformed the public health landscape and suggests what we might do to restore public trust in their e?cacy and safety.’ Professor Trish Greenhalgh OBE, University of Oxford Vaccine Nation, from world-leading epidemiologist Raina MacIntyre, examines the history of vaccines, how vaccines work, vaccine safety, public policy, new technologies like mRNA and the effects of the COVID pandemic on the anti-vaccination movement. At the same time as vaccination rates are falling globally, miraculous new developments in vaccines means we have new tools to fight cancer and other chronic diseases. At a critical time when the threat of an influenza pandemic is looming and disinformation is booming, MacIntyre argues that science must reclaim the stage, or we may lose centuries of gains that vaccines have brought to the world.
