Optimizing Real-Time Vaccine Allocation in a Stochastic SIR Model
Fig 13
Synchrony of epidemics represented by correlation and lag time as function of coupling.
Panel A: The correlation between the number of infectives I(t) in each city is plotted as a function of coupling fAB. Higher correlation corresponds to higher synchrony. Panel B: The lag time between epidemics is plotted as a function of fAB. A lower lag time corresponds to higher synchrony. For both plots, 25% of the total combined population is vaccinated after 5 days in an equal allocation, such that each city receives 10 vaccines. City A has 39 initial susceptibles and 1 infective; city B has 40 initial susceptibles. The recovery rate γ = 0.15 and the reproductive number r0 = 2.
