Key Concept

Key Evidence: A recent study estimated that, during the decade from 2011-2020, every US$1 invested in immunization programs in the world’s 73 poorest countries would yield a US$16 return on investment. Using an approach accounting for additional societal benefits of vaccination (the “full income approach”, which quantifies the value that people place on living longer and healthier lives), researchers estimated the return could be as high as US$44 per US$1 invested.
