- The need for a transparent and immutable process makes necessary and feasible the implementation of the blockchain technology beyond its application to the cryptocurrencies and adjusted beyond the traditional applications of smart contracts. One of these cases is the type of the second vaccine dose against the Covid-19. There are many reported cases where the second vaccine dose is applied with a different vaccine type, which contradicts the initial recommendations, and are empirical procedures, in some cases intentionally and maybe unintentionally in others. The problem to solve in the present study embraces the tracking, register, and avoidance of intentional applications of a different second dose type of the vaccine against the Covid-19 virus. The proposed method is a simulator of a smart contract that applies a core algorithm of the blockchain technology based on the SHA 256 cryptography procedure and the proof of work, all together in the C# programming language, avoiding any update of the chain to guarantee the original and unique process. The console application shows the break up of the chain if the data corresponding to the second dose is manipulated and the transport process is stopped, avoiding not only the delivery of a different vaccine dose type but the self-transport process.
