Benefits of Childhood Immunization 16 to 44 Times the Investment

To quantify the economic benefits of immunization, Sachiko Ozawa in the Department of International Health at the Johns Hopkins Bloomberg School of Public Health and coauthors assessed the return on investment (ROI) over a ten-year period (2011-2020).  They found that every dollar invested in vaccines during the decade was estimated to result in a return of 16 times the costs, taking into account treatment costs and productivity losses. They derived the estimates by looking not only at vaccine costs, but also supply chain and service delivery costs compared to the associated economic benefits of implementing vaccination programs in 94 low- and middle-income countries. When considering broader economic and social benefits the return on investment for immunization was 44 times the vaccination costs. 

Projections were for 2011-2020—declared the ‘Decade of Vaccines’ by the global health community. Read the entire study here.
