A Cross-Platform Mobile Application for Child Vaccination Management using React Native and Supabase

Abstract: Timely vaccination is critical in reducing childhood mortality and preventing the spread of vaccine-preventable diseases. Traditional vaccination tracking relies heavily on physical cards, which are often misplaced or forgotten, leading to missed immunizations. This research presents a Child Vaccination Management System, a cross-platform mobile application developed using React Native with Expo Router for the frontend and Supabase for backend and database services. The system offers secure user authentication, centralized vaccination record management, and real-time notification features to alert parents about upcoming doses. Designed with an intuitive UI, the application ensures seamless access to vaccination schedules, appointment management, and child health records. By eliminating dependency on physical documents and improving engagement through notifications, this solution enhances vaccination compliance. Future enhancements include AI-driven dose prediction, multilingual support, and integration with national immunization programs.
