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.
