Epidemic dynamics with incentive vaccination strategy. Snapshots of the stationary state configuration in square lattices with partial-subsidy (a) and free-subsidy (b) policies. Other parameters are $N=10^4$, $c=0.5$, $\sigma =1.0$, and $\delta =0.4$. The vaccination coverage $V$ (c) and epidemic size $R$ (d) as a function of $\sigma$ in homogeneous small-world network. The insets show the differences in the vaccination coverage and epidemic size between the partial-subsidy and free-subsidy policies, $V_P-V_F$ and $R_P-R_F$, respectively .
