This post shows some of the results we can find by using the simulation. As in the first version I made some tests, now I focused the new tests on the travelling and vaccination processes. These two processes were added in the last simulation version and represent some critical behaviour and processes in the virus spread.

By not receiving new agents with the infection, the simulation reaches the number of 0 infected agents on the 38th day using a vaccination percentage of 0.1 If we increase the vaccination percentage to 0.9 the 0 infected agents threshold is reached on the 39th day. Thus, we can infer that if we control the flow of agents in a city/simulation, the vaccination process does not have a considerable impact as it takes some time until the people
