Figure 6. Yearly incidence of IPD with different mixing parameters.

Figure 6

A, IPD incidence, VT; B, IPD incidence, NVT; and C, IPD overall incidence. Yearly incidence per 100,000 population over time when different mixing parameters are used: ε = 0.50, 0.85, 1.00; and the competition parameter is cN = 0.04. Each panel corresponds to a different age group. Note: the y-axis scales are different on each graph. Abbreviations: cN, competition parameter; ε, mixing paremeter; IPD, invasive pneumococcal disease; NVT, non-vaccine types; VT, vaccine types.
