Comparison of models: Vaccination during outbreak. Comparison of total clinical infection resulting when vaccination is introduced during a disease outbreak, for different vaccination rates. Left column is for T* = 10 days, right column for T* = 60 days. Top row: δ = 0.4; bottom row: δ = 0.9. The underlying model is a two age class network model, and vaccination rates in each (k,a) class are proportional to the number of susceptible individuals in that class. These rates are determined by the total infection in the general population, and saturate at a value of ω0 per individual per day (see Appendix), where ω0 = 1 (solid curve), 0.5 (dashed curve) or 0 (dotted curve).
