儿童早期干预的持久效应：布基纳法索全国疫苗接种突击计划

This study evaluates the long-term effects of a nationwide immunization program in Burkina Faso, known as the National Vaccination Commando Program, implemented in late 1984. Focusing on the measles vaccination component of the program and using a difference-in-differences approach, we find significant reductions in child mortality and improvements in educational attainment, including increased primary and secondary school completion. We also find significant positive effects on adult employment and agricultural productivity, yielding a substantial return on this early health investment. These findings underscore the lasting benefits of early childhood health interventions in low-income countries.
