Impacts of the selection strength β on epidemic dynamics under the partial- and free-subsidy policies for scale-free networks for large vaccination cost.
Vaccination coverage V (top panels) and epidemic size R (bottom panels) for the two subsidy policies for c = 0.9 and δ = 0.1, 0.4 and 0.7 (corresponding to left, central and right panels, respectively). Other parameters are the same as those for Fig. 9.
