The contribution of immunization to economic development

Immunization received intensive support during the 1980s in light of its demonstrable value, relatively low cost, and established infrastructure. The goal of universal childhood immunization was achieved in 1990 on the basis of a strategy of expanding coverage, technological improvements, and social mobilization. Although its impact is difficult to quantify precisely, the Expanded Programme on Immunization (EPI) has had significant positive effects on national and household economies as a result of the reduction of morbidity and mortality. It also has contributed to the development of the managerial and operational capacity of health systems and to the generation of widespread social and political support for health actions through a variety of different mechanisms. Priorities for the next decade include attention to policies to ensure the maintenance of high levels of coverage, continued technical development, and further strengthening of EPI planning and management.
