Blockchain-based Vaccine Supervision System

In recent years, vaccine safety incidents have occurred frequently. which endangers people's lives. Most existing vaccine management systems are distributively managed by different entities in the vaccine supply chain. This architecture makes it relatively easy to modify or even delete the vaccine circulation data maliciously, which leading to data privacy, transparency and authenticity issues. To protect vaccine safety, We propose a framework to supervise the vaccine circulation process by incorporating existing regulatory practices. The efficient storage of vaccine circulation protection have been protected which leveraging technologies such as smart contracts and the interplanetary file system.
