Effect of different vaccination strategies on the endemic prevalence (SIS model), a-b-c, and epidemic size (SIR model), d-e-f. The vaccination coverage represents the fraction of immune agents prior to the disease onset. In “Random”, we select the fraction of agents to vaccinate at random; in “Center”, we vaccinate first the agents that are assigned to central base locations, while in “Peripheral”, we prioritize vaccination for agents that belongs to the peripheral agents. We set: a-d p=0.1 and α=0.0, b-e p=0.4 and α=0.2, and c-f p=0.8 and α=0.4. Curves represent the median of 100 independent simulations; 95% confidence bands are displayed in gray. Agents are initially inside their base location and the infection starts after 100 steps to allow the agents to reach a steady-state configuration. The fraction of randomly chosen initial infected is 0.01. Other parameter values are L=100, N=10,000, D=109, Σmin=100, Σmax=10,000, σmin=1, σmax=1,000, v=500, c=4·10−4, ω=2.4, γ=2.1, λ=0.15, and μ=0.1
