Enhancing Vaccination Uptake Through Points Redemption Based Financial Incentives and Digital Platforms: an Open-label Cluster Randomized Controlled Trial Utilizing Community Mobilization and Empowerment Strategies

The intervention will span a duration of 12 months. All residents in the 8 intervention subdistricts/townships are available for participation; each participant household needs to register a household account on the digital platform. Each family member who completes targeted vaccine uptake or related health behaviors can earn points through two point-recording routes. Reward points will be accumulated on a household basis to encourage family members' engagement. Points can be redeemed for gifts on the digital platform and are only valid once.
