From: Correlated stochastic epidemic model for the dynamics of SARS-CoV-2 with vaccination

The graph visualizes the time dynamics of the model (1) in case of extinction for the class of infected population (i(t)) against parametric values taken from \(S_1\) and (0.5, 0.3, 0.2, 0.1) are the initial sizes for compartmental population.
