Results from the Basic Model. Dependence of final epidemic size and final number vaccinated on: probability of death due to disease d _inf when d _vac = 0.001 (a), probability of death due to vaccine d _vac when d _inf = 0.03 (b), percentage of population with previous immunity (c), and probability to vaccinate ρ (d) in the Basic Model. Error bars represent two standard deviations from the mean across 20 simulations per data point. Note that d _inf = 0.3 (Table 1) lies to the right of the range illustrated in Figure 1a; we did not plot the results for d _inf > 0.07 because they are qualitatively unchanged from the case d _inf = 0.07.
