Title: Mobile Nudges to Increase Early Vaccination Coverage in Rural Areas: A Pilot Investigation in Ghana's Northern Region
Brief Summary: Despite major progress made in vaccination coverage overall, timeliness of vaccines remains a key concern in many settings. At the same time, access to mobile phones has increased rapidly, offering new opportunities to track and deliver health services. This research project uses these newly available mobile phone networks to simultaneously address two of the biggest bottlenecks in vaccine delivery: timely documentation of births, and lack of maternal effort or access to get essential vaccines. To increase documentation, investigators will train volunteers in each community to report new births via mobile phone to a central coordinator, and send small monetary rewards via mobile phone to volunteers for this reporting. To increase vaccination coverage, investigators will send reminder messages directly to mothers, and will also test small monetary rewards to volunteers and to mothers as an incentive to complete recommended vaccinations. The designs to provide vaccination encouragement will be tested through a small community randomized controlled trial in 15 selected villages in Ghana's Northern region. The primary outcome for the pilot study will be the percentage of children who received both the polio birth dose (OPV0) vaccination within two weeks of life (14 days) and the BCG vaccination within the first four weeks (28 days) of life.
