The UK National Health System (NHS) has announced it will use blockchain technology for its Covid-19 vaccines. The NHS has contracted with Hedera Hashgraph to monitor vaccines in cold storage.The UK will be able to track covid-19 vaccines regularly and efficiently with Hedera’s distributed ledger technology (DLT), thanks to the agreement with Hedera Hashgraph.CoinDesk reported that the UK has contracted a software company called Everyware to monitor the temperature of existing vaccines. Along with the software that Everyyware offers, temperature monitoring of vaccines will take place around the clock. Hedera Hashgraph will ensure that vaccine temperature data is recorded smoothly.Strong follow-up is essential to ensure vaccines are not disrupted.Covid-19 vaccines are sensitive products that must be stored at a certain temperature. For this reason, temperature monitoring must be carried out regularly so that vaccines don’t deteriorate. Engineer Steve Clarke, of the South Warwickshire NHS, said that as they monitor the temperature requirements of vaccines, they also began to understand the importance of using new technologies.Hospitals in the South Warwickshire, Stratford, Avon county, and Warwick of England will be the first regions to experiment the blockchain technology. According to the statement, as the vaccine’s distribution area expands, so will the use of the new technology.What is Hedera Hashgraph?Hedera is a blockchain platform using distributed ledger technology. With this feature, Hedera believes that users will be more secure in all transactions they make on their network. Similar to blockchain networks such as Bitcoin and Ethereum, Hedera is a faster, safer, fairer and energy-saving platform. Hedera works with large companies such as Google, IBM, Boeing, LG.
