Group Type: PLACEBO_COMPARATOR

Call

Intervention Type: BEHAVIORAL

A New Incentives' team member reminded caregivers of their child's measles immunization date and the total amount of incentive they would receive once their child was vaccinated. If the caregiver could not be reached on the first attempt, the team made additional attempts at different times of the day on five different days across two weeks (up to 10 attempts were made per caregiver).

Small Additional Incentive

Respondents were told they would receive 1000 NGN more than originally promised by New Incentives' (either 2000 or 3000 NGN) when they brought their child for measles immunization.

Group Type: EXPERIMENTAL

Cash Incentive

Intervention Type: BEHAVIORAL

During the phone call, New Incentives' team member promised a greater cash payment from New Incentives' staff members at primary health care facilities when infants enrolled in the program and received their measles vaccination.
