Evaluation report on Strengthening Immunization Services to Reach and Recover Zero-Dose Children in Mozambique Through the Use of Digital Tools

The Big Catch-Up (BCU) initiative in Mozambique aimed to address immunisation gaps and reach zero-dose and under-immunised children, supported by strengthened monitoring and reporting systems. This case study examines the use of digital tools in implementing the BCU across seven provinces, focusing on their contribution to data collection, monitoring, supervision, and evidence-informed decision-making. It highlights how existing digital platforms were adapted to support implementation, while identifying challenges related to connectivity, equipment, interoperability, technical capacity, and sustainability. The study draws lessons on strengthening digital health systems and institutionalizing data-driven monitoring to support routine immunization and sustain the gains achieved through the BCU.
