VAXBLOCK is a proof-of-concept blockchain-based application developed to improve vaccination management in developing countries. The application, deployed on the Ethereum blockchain, enables secure management of vaccination records, appointment requests, and vaccine inventory. By ensuring data integrity and privacy, VAXBLOCK aims to enhance healthcare delivery and vaccination coverage. It has potential to integrate immunization records with Electronic Health Records (EHR's) using blockchain technology and smart contracts for low-resource countries (LRCs). Future plans include usability testing and integration with existing healthcare systems.
