In a post in the Bill & Melinda Gates Foundation’s “Impatient Optimists” blog, David Ferreira, managing director for innovative finance and head of the Washington, D.C., office of the GAVI Alliance, examines immunization efforts in Ethiopia. “Just a decade ago, Ethiopia’s immunization coverage rate was as low as 28 percent, by measure of the [WHO]/UNICEF, and no more than 51 percent by Ethiopia’s own estimate,” he writes, adding, “Today, Ethiopia has a health system that is on its way to becoming a model for others, transformed through a decentralized, robust approach led by the country’s Ministry of Health.” As a result, “Ethiopia has met — almost three years early — U.N. Millennium Development Goal 4, reducing child mortality by two-thirds,” he notes (12/17).
