Calling the Shots examines the basic strategies that finance the national immunization system in the current health care climate. It is a comprehensive volume, rich with data and highlighted examples, that explores: the evolution of the system in light of changing U.S. demographics, development of new vaccines, and other factors; the effectiveness of public health and health insurance strategies, with special emphasis on the performance of the Section 317 program; and the condition of the infrastructure for control and prevention of infectious disease, surveillance of vaccines rates and safety, and efforts to sustain high coverage. Calling the Shots will be an indispensable resource to those responsible for maintaining our nation’s vaccine vigilance.
