<p><b>A</b>, IPD incidence, VT; <b>B</b>, IPD incidence, NVT; and <b>C</b>, IPD overall incidence. Yearly incidence per 100,000 population over time when different competition parameters are used: c<sub>N</sub> = 0, 0.04, and 0.37; and the mixing parameter is ε = 0.85. Each panel corresponds to a different age group. Note: the y-axis scales are different on each graph. Abbreviations: c<sub>N</sub>, competition parameter; ε, mixing parameter; IPD, invasive pneumococcal disease; NVT, non-vaccine types; VT, vaccine types.</p>
