Svetha Janumpalli, the Founder and CEO of New Incentives, is this episode’s guest. New Incentives is an innovative nonprofit that uses small cash payments to boost childhood vaccinations in North West, Nigeria, which has some of the lowest childhood vaccination rates in the world. In partnership with local governments, it provides these cash transfers, typically around $11, to caregivers after their infants receive vaccines, and uses rigorous data and monitoring to ensure that the dollars it spends are making the largest possible impact. Its programs have already doubled the rate of childhood vaccination, leading to huge gains in the health of the communities involved, and New Incentives is constantly looking for ways to make an even greater impact.
