简要总结
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.
详细描述
Despite major progress made in vaccination coverage overall, timeliness of vaccines remains a key concern in many settings. Early vaccination coverage is particularly low in settings where a large share of women deliver at home, as it is the case in Ghana's Northern region, where only a minority of women seek out facilities for delivery. In Ghana, 95% of children receive BCG vaccination within the first two years of life, but only about half of these children receive the vaccine within the first 30 days after delivery. Less than 50% of children in Ghana's Northern region receive Bacillus Calmette-Guérin (BCG) vaccines within the first three months of their life, and less than 40% get polio vaccination, exposing a large number of infants to these diseases.
Recent research conducted in this region shows that the large majority of households have access to mobile phones, even in the most rural areas. this project uses 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 essential vaccines. Evidence from other low resource settings suggests that even small rewards can often result in substantial increases in vaccine uptake - investigators will test this hypothesis using mobile networks in rural areas of Northern Ghana.
The main objective of this study is to assess the extent to which mobile-phone based reminder or reward systems can increase early vaccination coverage. Investigators will assess two specific interventions through the pilot study:
- a mobile-phone based call and text system which will be used to contact mothers to highlight the importance of early vaccinations, provide reminders (nudges) to mothers encouraging them to get their newborn vaccinated and providing information on where and when vaccinations are available in their community.
- a community volunteer-based system that will provide small mobile credit rewards to both community volunteers and mothers for completing the early vaccinations within the first month of newborn life.
Research Hypotheses (H1-3) H1: Nudging mothers through voice and text messages will increase early vaccination coverage.
