A gripping journey through the past, present and future of vaccines. Vaccination is arguably the greatest public health achievement in history, yet the disappearance of many diseases has also seen an increased focus on the side effects of vaccines and the rise of the anti-vax movement. The COVID-19 pandemic propelled anti-vaccination sentiment into the mainstream – including from some leaders in the medical profession – in an explosion of pseudoscience and disinformation that’s made it increasingly difficult to separate fact from fiction. In Vaccine Nation, internationally acclaimed epidemiologist Raina MacIntyre examines the history of vaccines and how they work, vaccine safety, public policy, cutting-edge new technologies, and the miraculous new developments in vaccines to fight cancer and other chronic diseases. At a critical time when vaccination rates are falling globally, MacIntyre argues that science must reclaim the stage or we will lose centuries of gains that vaccines have brought to the world.
