Comparing the effectiveness of ring and block-vaccination strategies on networks

Validation of the theoretical framework for the case of Preventive—static—scenarios.
For the cases of ring (left panel) and block (right panel) vaccinations. The radius of vaccination spans from 0 (baseline that corresponds to random vaccination) to 3. As the vaccination strategy occurs before the propagation of the disease, we validate our results by analyzing the evolution of the giant component as a function of the percentage of vaccinated nodes ϕ, i.e., the resulting diluted network after the percolation process. Each horizontal panel corresponds to the same network structure with N = 104 nodes, ranging from more homogeneous on the top, a random regular graph with , to more heterogeneous on the bottom, a scale-free network with degree exponent
and
and
. In the middle, results are shown for Erdős-Rényi nets with
. See the Methods Section for details further details on these network ensembles. Experimental results are averaged over 103 independent stochastic simulations.
