Blockchain model applied to the distribution chain of the
COVID-19 vaccine
Two possible supply chains are considered through which the vaccine will
have to pass:
Emerging chain: This supply chain aims to deliver the vaccine
as quickly as possible to all countries that require it, for a quick
application to all those infected, shown in Figure 1 , in three
phases (A: Sent, B: Storage, C: Application) the entire distribution
is divided until it reaches its final recipient. Figure 1 shows the
distribution in the emerging chain.
