We estimate that the United States invested approximately US dollars 35 billion in polio vaccines between 1955 and 2005… The historical and future investments translate into over 1.7 billion vaccinations that prevent approximately 1.1 million cases of paralytic polio and over 160,000 deaths. Due to treatment cost savings, the investment implies net benefits of approximately US dollars 180 billion, even without incorporating the intangible costs of suffering and death and of averted fear. Retrospectively, the U.S. investment in polio vaccination represents a highly valuable, cost-saving public health program.
