Mobile-based Vaccine Tracking System using Ethereum Blockchain and QR Code

In the current landscape of vaccine distribution, the pervasive threat of illicit distributors exploiting transaction data vulnerabilities raises serious concerns about vaccine safety and authenticity. To address this challenge, this research introduces an innovative blockchain-based system aimed at countering vaccine counterfeiting and enhancing the transparency of distribution processes. Leveraging Supply Chain Management principles, the system orchestrates the complexities of vaccine distribution, offering comprehensive visibility from central government initiation to healthcare professional administration via an intuitive mobile application. Blockchain technology strengthens data security, guarding against fraudulent activities, while the integration of QR codes expedites data processing and furnishes patients with detailed vaccine information. All transactions are executed through smart contracts, ensuring trust and transparency, with completed contracts securely recorded on the Ethereum blockchain. This research presents a groundbreaking solution to combat vaccine counterfeiting, establishing a resilient and transparent framework for distribution, providing real-time monitoring, and empowering patients and stakeholders with essential vaccine details. In summary, the amalgamation of Ethereum blockchain technology and QR codes in this mobile-based vaccine tracking system offers a transformative approach to fortify the safety and integrity of vaccine distribution, ultimately benefiting society as a whole.
