A large-scale study conducted in over 900 villages in Haryana, India, has found that a carefully chosen mix of low-cost interventions including financial incentives, text message reminders, and community outreach can significantly increase childhood vaccination rates. The research, led by economists at the Massachusetts Institute of Technology (MIT), showed that one combination of these tactics led to a 44 percent rise in immunizations against deadly diseases.
The experiment, carried out between 2016 and 2019, was a collaboration between MIT’s Abdul Latif Jameel Poverty Action Lab (J-PAL) and the Government of Haryana’s Department of Health and Family Welfare. The findings were published in the journal Econometrica in a paper titled "Selecting the Most Effective Nudge: Evidence from a Large-Scale Experiment on Immunization."
