The effects of population structure on the final vaccine coverage level for varying relative cost c. The simulations are conducted for R 0 = 1.5 (upper left), R 0 = 2.0 (upper right), R 0 = 2.5 (bottom left), and R 0 = 3.0 (bottom right), respectively. The results are averaged over 50 independent network simulations with network size N = 5000 and average degree 〈k〉 = 4. As the relative cost c increases from zero to a critical value, the final vaccine coverage drops from 100 percent to 0 for all types of networks. It can be observed that the more diverse the network becomes (e.g., scale-free networks), the larger the critical relative cost will be.
