Main parameters used to model the propagation of some virus on a network, under some vaccination rate and strategy, where some individuals adopt anti-vaccination views. In terms of the virus, the three parameters are the probability of infection $\pi$, the recovery time $\tau$ and the lethality $\varphi$ and are somehow related. The probability that a susceptible person is infected by an adjacent infected node is $1-{(1-\pi )}^{\tau }\approx 0.51$ (for the values of the parameters used)since they have interactions for a period of $\tau$ days. The model parameters, which are used to detect the impact of anti-vaccine views and to measure the results of a vaccination strategy are the vaccination rate $\nu$ and the persuasiveness of the views $\theta$, which are considered for all of its potential values in the [$0,1$] interval.
