Primary Outcome Measures

Name	Time	Method
Measles Vaccination Coverage Rate	We assessed whether eligible infants received measles vaccination at any time during the 4 month study period. Children were a minimum of 9 months at the beginning of the study and a maximum of 7 years at the end of the study.	The outcome of interest is the measles coverage rate among the eligible randomized infants. Coverage is measured using the measles vaccination information recorded on the child's health card. The child health card information was immediately entered into the New Incentives' database by their field staff when they disbursed the cash incentives at program clinics. Information from the New Incentives' database was used for the analysis.
