PlanFeld: Expanding Immunisation Reach With Digital Microplanning in Lagos State

A Case Study

The implementation of Planfeld in Lagos State represents a significant shift from fragmented, manual microplanning systems to a digitally integrated and geospatially accurate approach to immunisation
planning. By combining high-resolution settlement data, capacity building, real-time tracking, and strong stakeholder coordination, the intervention enhanced the health system’s capacity to identify zero-
dose populations, improve visibility of campaign coverage, reduce planning inefficiencies, and support more informed, evidence-based decision-making.
