From: An approximation of herd effect due to vaccinating children against seasonal influenza – a potential solution to the incorporation of indirect effects into static models

Figure 3

Point estimates from studies evaluating herd effect in a subpopulation in published studies. Single data points show point estimates of relative risk (RR) of influenza infection in subpopulation analysed for herd effect plotted against effective vaccine coverage in children. Point estimates from studies evaluating herd effects at a community level are shown as lines (derived by connecting lines through the point where RR = 1.0 and effective coverage = 0%) for comparison.
