Prevalence of carriage with 4CMenB vaccine. The prevalence of carriage with vaccine programs 7 (a,d,g), 8 (b,e,h) and 9 (c,f,i) for the 4-strain model (a-c, showing “C”, “B”, “Nl”, and “Other”), the 2-strain model (d-f, showing “B” and “Other”), and an overlay of model outputs for both models (g-i, showing “B” and “Other”). The initial carriage prevalence of serogroup “Other” is different in the 2-strain and 4-strain models because of the filtering procedure used during model parameterization. The same plot with standard deviations of model outputs appears in Additional file 1: Figure S5
