Health workers are essential to the success of immunisation programs. They vaccinate, generate demand, manage cases, engage with communities, and educate the general population. They also generate data that is essential for immunisation planning, service delivery, and monitoring. Many health systems struggle with issues such as inadequate training for health workers, limited supportive supervision, limited communication, incomplete data reporting and ineffective mechanisms for tracking unvaccinated or under-immunised children.

Digital technology presents a transformative opportunity to support the efforts of health workers in delivering immunisation services. Digital health interventions, such as mobile health (mHealth) applications, electronic immunisation registries (EIRs), geo-locationenabled case management tools, clinical decision support tools, and checklists, provide innovative solutions by streamlining data capture, improving communication and quality of health service delivery, and enabling triangulation with disease occurrence data to support real-time decision-making. These tools help health workers enhance the accuracy and efficiency of immunisation services and contribute to better health outcomes, such as timely completion of immunisation schedules and reduced loss to follow-up

This Technical Brief, developed as part of the effort by Gavi, the Vaccine Alliance to expand beyond Digital health Information to Digital Health, documents the opportunities that digital health interventions provide to health workers to address critical challenges in immunisation delivery and enhance overall health system performance. The brief reviews existing literature and draws on insights from key stakeholders to provide a comprehensive overview of digital health interventions for health workers and their impact on immunisation services. It outlines strategic recommendations for integrating these technologies into immunisation programs to maximise their benefits, emphasising the need for robust digital infrastructure, training, and stakeholder engagement.
