The outbreak of the COVID-19 pandemic led to a worldwide impact on healthcare. At the same time, it also increased the speed of embracing digital technology. Blockchain is one of the emerging digital technologies that have unique features, such as transparency decentralization, and immutability. This technology can help in various domains.
Zuellig, a large pharmaceutical company in Asia came up with a blockchain-powered system for tracking how good the quality of the COVID-19 vaccines is. It is known as “eZTracker” and enables a user to immediately verify the authenticity and provenance of vaccines. The system does so by scanning the package’s QR code. Let us now see a couple of examples of how countries are adopting blockchain-based systems to fight the pandemic:
Network to track vaccination in Brazil
The National Health Data Network uses blockchain but was not created specifically for fighting the coronavirus. Instead, it is a part of an ambitious strategy to digitize the entire healthcare system of Brazil. At the same time, the system was utilized to respond to challenges related to COVID-19 since the end of 2020. The key utilization of this network in Brazil is vaccination tracking.
Blockchain vaccine passports in South Korea
In April, last year, the government of South Korea was the first nation to launch a blockchain-powered vaccine passport during the coronavirus crisis. When the evidence of vaccination is put on a distributed ledger, it makes sure that the document is authentic. The revolutionary app is called COOV and was created by Blockchain Labs, a London-based company. Users could install it from Google Play Store, as well as, App Store.
