South Korea will use blockchain to prevent counterfeit vaccine passports

Blockchain technology is being used to cement confidence in the integrity of new health surveillance measures such as COVID-19 vaccine passports. South Korea, which has begun its COVID-19 vaccine rollout for residents over 75 years of age, has revealed plans to use blockchain technology to certify forthcoming vaccine passports for immunized citizens. 

According to Reuters, Prime Minister Chung Sye-kyun told a government meeting that a new mobile app will be used to manage digital proofs of vaccination, and is expected to launch later in April. Blockchain technology will be used to ensure that citizens are not able to forge evidence of having ostensibly received a jab. 

Whatever its eventual approach toward vaccine passports will be, the U.K. has, like South Korea, recognized the usefulness of blockchain technology for managing the complex logistical challenges of the vaccination procedure itself. In addition, the Brazilian government has indicated its intent to use the Hyperledger Fabric blockchain framework for keeping tabs on its own vaccinated citizens.
