Country Sierra Leone
Globally, there is a standard course of 5 vaccines over the first year of life. In Sierra Leone, 99% of children get the first vaccine, but only 69% of children complete all 5 vaccinations by the age of one. This study asks if we can increase timely and complete vaccination by allowing parents to show to others that they have vaccinated their child. Researchers introduced a signal in the form of coloured bracelets that children receive upon vaccination in Sierra Leone. We ask you to predict the short and long-run effects of the signalling intervention. 10% of respondents to this survey will receive an accuracy reward of up to $100. There is also a $40 reward if you complete at least 4 of these long-run surveys.
