High-Risk Immunization Strategies for Multiethnic Regions

Figure 3

At a fixed vaccinating rate 𝛿=0.3, the computer simulations of SIRS model with high-risk immunization on BA scale-free networks. 𝜁_𝐴𝐵=𝜁_𝐵𝐶=𝜁_𝐴𝐶=0.7. (a) When 𝑁=1000, the variation of infected density 𝐼(𝜆) as a function of 𝜆. (b) When 𝑁=3000, the changing of infected density 𝐼(𝜆) as a function of 𝜆.
