Comparing the effectiveness of ring and block-vaccination strategies on networks
Fig 4
Asymptotic size of the epidemic (total fraction of recovered individuals R) as a function of the virulence of the diseases β for the preventive scenario.
Solid lines are theoretical predictions, and symbols correspond to stochastic simulations. Grey lines correspond to the case with vaccination strategies, while violet lines correspond to the standard SIR. The initial size is N = 104, and the results are the average computed over 103 realizations. We consider scale-free networks with exponent ,
and
. The recovery probability is set in
, and the vaccination radius is equal to r = 2. Different lines refer to different initial percentages of vaccinated nodes ϕ.
