Blockchain Tracking System of COVID-19 Vaccination

Abstract

Ever since the spread of COVID-19 pandemic, the entire pharmaceutical industry responded to the outbreak with combined efforts to develop a reliable vaccine. Currently there are six major manufacturers of COVID-19 vaccinations, Pfizer-BioNTech, Moderna, Johnson & Johnson, Astrazeneca, Sputnik and Sinopharm. The global vaccination campaign started in early December of 2020. On April 19, 2021, more than 905 million vaccine doses were administered worldwide. Because most vaccines needed more than one does to provide adequate protection, and some vaccine types were paused due to potential health risks, an imbalance in the distribution of vaccines among the general population and discrepancy in the vaccination records occurred. The answer to this problem lies in the implementation of a Blockchain vaccination tracking system. This shall provide a reliable solution that shall help governments track the vaccination process and keep accurate, authentic records. A Blockchain system shall provide authentic data about the number of people vaccinated and how many doses each of them received, and the exact date and time of each does. The Blockchain system shall facilitate the shipping, management, and delivery of the COVID-19 vaccine and shall help countries learn, and make decisions on how to plan and manage the vaccination process. In this paper, we propose the development of a Blockchain vaccination tracking system to enable governments deliver COVID-19 vaccine to its citizens effectively and efficiently.
