Vaccines have helped mankind to tackle the dire threat of infectious disease for more than a hundred years. They have become key tools of public health and scientists are charged with developing them as quickly as possible to combat the emergence of new diseases such as Zika, SARS and Ebola. But why are growing numbers of parents all over the world now questioning the wisdom of having their children vaccinated? Why have public-sector vaccine producers been sold off? And can we trust the multinational corporations that increasingly dominate vaccine development and production? In this controversial new book, Stuart Blume argues that the processes of globalization and people's unsatisfied healthcare needs are eroding faith in the institutions producing and providing vaccines. He tells the history of immunization practices, from the work of early pioneers such as Louis Pasteur and Robert Koch to the establishment of the World Health Organization and the introduction of genetic engineering. Immunization exposes the limits of public health authorities while suggesting how they can restore our confidence. Public health experts and all those considering vaccinations should read this timely history. - Publisher.
