Fig 7. Fraction of infections that do not die out in their early stages as a function of the immunization budget b and the immunization method.

For each immunization type and b ∈ {1%, 2%, 5%, 10%, 15%}, 5000 simulations on the encounter network initiated at random single seeds are run. The x-axis shows b (% of population that receives immunization), the y-axis shows the fraction of infections whose final size is above 0.1% of the entire population (taken as an indicator that an infection did not die out in its early stages). Lower values of the y-axis correspond to more effective immunization strategies.
