The Zero-Dose Learning Hub (ZDLH) is composed of learning hubs in Bangladesh, Mali, Nigeria, and Uganda, and at the global level. Country learning hubs generate and use data to identify and address barriers to immunization for zero-dose children, understand what interventions work to ensure timely immunization and reach zero-dose children, and to improve monitoring and measurement. This presentation offers a number of recommendations across the Identify-Reach-Monitor- Measure-Advocate framework and contains links to additional resources.

The Nigeria Zero-Dose Learning Hub aims to enhance immunization equity by generating evidence and insights to guide policy and program improvements. Funded by Gavi and implemented by AFENET and AHBN, the project addresses barriers such as low vaccine confidence, gender inequality, and economic challenges. This presentation shares findings on regional variation in barriers to immunization, the decentralized immunization monitoring approach for timely monitoring and programmatic course correction, implementation research activities to assess the effectiveness and costs of the identify, enumerate, and vaccinate (IEV) strategy, capacity building, and advocacy and engagement.
