Simulations were based on values used in Nowak and May [1], Nowak and Bangham [3] and Wodarz and colleagues [4]. Immune responsiveness (ci) and the connectivity coefficient (ωi) were varied throughout this paper. Their specific values for each simulation experiment are described in the Methods section.
