Figure 1. Effect of PEV (a,c,e) and BSV (b,d,f) on infectivity to vector over 20 years when delivered via EPI (black), EPI with boosters (blue) and EPI with 95% mass vaccination (red) for transmissions settings of EIR 5.25 (a,b), 21 (c,d) and 168 (e,f).

Results obtained assuming a vaccine efficacy of 80%, half-life of 10 years and homogeneity value of 10. Note that the blue and black lines almost overlap.
