Vaccinology, the concept of a science ranging from the study of immunology to the development and distribution of vaccines, was a word invented by Jonas Salk. This book covers the history of the methodological progress in vaccine development and to the social and ethical issues raised by vaccination. Chapters include 'Jenner and the Vaccination against Smallpox,' 'Viral Vaccines,' and 'Ethical and Social Aspects of vaccines.' Contributing authors include pioneers in the field, such as Samuel L. Katz and Hilary Koprowski. This history of vaccines is relatively short and many of its protagonists are still alive. This book was written by some of the chief actors in the drama whose subject matter is the conquest of epidemic disease.
