Vaccines promote health: unlike many other health interventions, they help healthy people stay healthy, removing a major obstacle to human development.
Vaccines save lives and costs: every dollar spent on childhood immunizations yields US$44 in economic benefits. These include savings on medical costs and productivity loss.4
