Fig 8. Final infection size as a function of the immunization method and the infection start time.

Given immunization budget b = 5% of the entire population, for each immunization type, 5000 simulations on the encounter network are initiated at random single seeds. Each panel considers a target infection size expressed as a percentage of the entire population. The x-axis shows the infection start time t₀(s) of seed s, the y-axis shows the fraction of infections whose final size is above the given target. Lower values of the y-axis correspond to more effective immunization strategies.
