Brazil has planned to use a blockchain-based system called the National Health Data Network or RNDS to track COVID-19 vaccinations, as a recent YouTube webinar from the Ministry of Justice and Public Security hosted discussion on blockchain’s usefulness in several categories, including the fight against corruption.
It has been reported by Reuters that at the beginning of September, the country is not likely to push a mandatory vaccine, while September 9 news reported by MercoPress estimated a 2021 debut date for a COVID-19 shot in the country.

However, Elmo Raposo Oliveira, the Ministry of Health’s Coordinator of Systems Development, said that constructed using the Hyperledger Fabric blockchain framework, the system keeps tabs on anyone who has received a COVID-19 vaccination.
“So the Covid-19 vaccine will already be within our RNDS structure. So, when you get the vaccine you will already hit the RNDS here and we will already know who took it.”
After each injection, the system receives data regarding which folks got the vaccine, and uploads that data to the blockchain.
“RNDS ‘objective is to promote the exchange of information between the points of the Health Care Network, allowing continuity of care in the public and private sectors.”
Thus, the system allows for greater case and vaccine tracking, data efficiency and clarity, as RNDS includes other patient information, such as treatments and medications received.
