The transparency of latest health monitoring measures such as COVID-19 vaccine passports is being bolstered by blockchain technology.
South Korea has announced plans to use blockchain technology to certify future vaccine passports for immunized people, which has started the introduction of the COVID-19 vaccine for residents over 75 years old.
According to Reuters, Prime Minister Chung Sye-kyun announced at a government meeting that a new mobile app would be used to handle digital proofs of vaccination, and that it will be released later this month. People would not be able to fake proof of having ostensibly obtained a vaccine thanks to blockchain technology.
“The introduction of a vaccine passport or ‘Green Pass’ will only allow those who have been vaccinated to experience the recovery to their daily lives,”Chung said.
The vaccine passports are also aimed at international tourists, who will be sponsored by the app and allowed to enter the country only if they have certifiable evidence of vaccination.
In the midst of the COVID-19 pandemic, several countries and foreign blocs, including China, Israel, and the European Union, have either already adopted or indicated their willingness to adopt vaccine passports domestically and/or to promote cross-border travel. Other nations, such as the United Kingdom, are also divided politically about the possible benefits and disadvantages of a certificate-based system.
Whatever its final role on vaccine passports, the United Kingdom, like South Korea, has acknowledged the importance of blockchain technology in handling the dynamic logistical challenges of vaccination. Furthermore, the Brazilian government has announced that it plans to use the Hyperledger Fabric blockchain system to monitor its own vaccinated citizens.
