ABSTRACT
COVID-19 vaccinations have been approved for public immunization and are going through clinical trials. Vaccinating a billion people of India is a huge challenge. Tracing, last mile delivery, data privacy, double spend of dosage, and multiparty authorization pose serious challenges for providing COVID-19 vaccines. Policies have been framed on who gets the access to the vaccine. However, there is a need of a technological solution to create an efficient vaccine distribution or delivery system. This paper proposes a novel blockchain enabled vaccine delivery system in the context of India. A consortium blockchain has been proposed which has different participants, like the UIDAI, healthcare facilities, pharmaceutical supply chain, etc. These participants are responsible for authenticating the beneficiary of the COVID-19 vaccine. Sequence diagram of how the beneficiary is authorized to access the vaccine has been proposed. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
