A Framework for Covid-19 Vaccine Management System Using Blockchain Technology

The SARS-CoV-2 first surfaced in 2019 in China and later spread across the globe causing a pandemic. Immunisation has thus far been considered to be mankind’s weapon of choice in the frontline fight against the virus defined as Covid-19. Mass vaccination programmes carried out by nations are closely related to public health information, data safety and data security. As countries roll out the immunisation efforts, cyber offenders try to exploit people’s personal health data and inoculation records while citizens can also be exposed to fake vaccine certificates issued by hackers. To prevent such any data breach or data exploitation, an effective system is urgently required to be in place that ensures the maximum security at a time of the unprecedented global crisis. Blockchain can be the perfect solution in this case thanks to its transparency, trustworthiness, and decentralised operations. We have proposed a blockchain based framework for covid 19 vaccination process to provide data immutability, transparency and correctness of beneficiary registration for vaccination, eliminating identity thefts and impersonation, tamper proof self-reporting of side effects, person identification and vaccine certification.
