Vaccination coverage under strong responsiveness to differences of payoff (α = 15) in a (A) homogenous Poisson network, (B) urban network, and (C) exponentially-scaled power law network.

<p>Vaccine coverage is given as a function of <i>r</i> for the two extreme cases: fully payoff maximization (Θ = 0) and fully imitation (Θ = 1). Parameters are identical to <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002469#pcbi-1002469-t001" target="_blank">Table 1</a>, except α = 15.
