Figure 4

Linear relationships between effective vaccine coverage and herd effect. Point estimates identified from the literature review and linear relationships (derived from Equation 3 in Bauch et al. (2009) [12] or from fitting to general linear equation) between relative risk of infection in the unvaccinated population as a function of (A) effective coverage in children, and (B) change in effective vaccine coverage in entire population induced by varying levels of effective coverage in children.
