PAHO promotes digital innovation to improve vaccination recordkeeping in communities with limited connectivity
Washington, D.C., November 5, 2025 (PAHO) – The Pan American Health Organization (PAHO), working with Peru's Ministry of Health, has launched a new digital solution designed to enhance vaccination data recording and management in regions with poor or no internet access.
The pilot project, known as the Offline Immunization Digital Application, was tested in Peru’s border regions of Amazonas, Madre de Dios, and Loreto. The tool aims to modernize how vaccination data is captured and used in remote communities.
The “Vacuna Offline” system, developed under the World Health Organization’s SMART Guidelines interoperability framework, allows healthcare workers to register immunization data directly during patient care—even without internet access. Once the device reconnects online, all data is automatically synchronized with national health databases, ensuring accuracy and timely updates for health planning and policymaking.
“The application represents not only progress for Peru but also for a potential digital public asset that can serve as a model for other countries in the region that are facing similar challenges,” said Piedad Huerta, Head of PAHO’s Country and Subregional Coordination Office, during the launch event in Lima.
A comparative review was also conducted between traditional paper-based vaccination records and the new digital system to assess effectiveness and efficiency.
