In December of 2023 the Zero-Dose Learning Hub (ZDLH) and the Nigeria Country Learning Hub (CLH) held a learning agenda workshop to adopt and validate learning questions that meet country priorities, map zero-dose (ZD)-related data collected by stakeholders, and co-create data sources and methodology for collecting data relevant to answering the learning questions. Fifty participants attended, including representatives from international partners, government agencies, and country implementers working to reach ZD children in Nigeria. This report summarizes the meeting activities, discussion, outcomes, and next steps for the ZD practitioners in Nigeria.
