UK Hospital Using Blockchain to Track COVID-19 Vaccines

Two British hospitals are actively using blockchain technology to keep tabs on the storage and supply of temperature-sensitive COVID-19 vaccines.

Tuesday, January 19, South Warwickshire NHS Foundation Trust, which is part of the government-run National Health Service and administers four hospitals in central England, has begun using the Hedera Hashgraph system to keep track of whether COVID-19 vaccines are being stored at the correct temperatures, Hedera and Everyware, a U.K. software company that is overseeing the project.

Tom Screen, Technical Director at Everyware said that its sensors would monitor the temperature of refrigerators storing vaccines. Then, it transmits the data to its own cloud platform where it is encrypted and then passed on to Hedera’s blockchain network.

“We can absolutely verify the data that we’ve collected from every single device,” Screen said. “We make sure that data is accurate at source, and after that point, we can verify that it’s never been changed, it’s never been tampered with.”

The system will “allow us to demonstrate our commitment to providing safe patient care,” said Steve Clarke, Electro-bioMedical Engineering Manager at South Warwickshire NHS in a statement.
