Local risk perception enhances epidemic control
(A) The proportion of individuals that are infected increases and then declines slightly as R0 increases, across all three decision strategies. (B) The proportion of individuals that choose to vaccinate initially increases sharply with R0 across all three strategies, but then declines for only the local count strategy. (C) Herd effect is the proportion of infections averted per vaccinated individual, and is highest for the local count strategy across all R0. All values are averages across 500 stochastic simulations.
