Effects of vaccination in the two models for different administration rates and campaign durations. Epidemic measures are shown for proportional (open circles) and non-proportional (filled dots) models. Final size, peak size, peak time, and epidemic duration are plotted as a function of the difference between the vaccination start time (t _a ) and the onset of the initial outbreak (t ₀; solid gray line). The vaccination campaign durations and daily administration rates are as follows: (1) 56 day campaign with k = 0.001 (proportional) or (non-proportional) (a1-a4), (2) 28 day campaign with k = 0.01 or (b1-b4), and (3) 3 day campaign with k = 0.1 or (c1-c4).
