Vaccines certainly prevent death and suffering, but they also save money. Vaccination is one of the most cost-effective health-care investments available.
In the United States, cost-benefit analysis indicates that every dollar invested in a vaccine dose saves US$2 to US$27 in health-care expenses.
The eradication of smallpox alone has saved the United States more than US$3 billion between 1983 and 1994. The benefits are just as striking if one looks to the future.
