Figure 3

Effect of (a) sense of caution factor, \(d_I\), and (b) sense of safety factor, \(d_V\) on pandemic trajectory. The dashed blue bar represents the introduction of a vaccine with 95% effectiveness, at a fixed rate of 0.3% of the population per day. Extreme values of \(d_{I}\) represent the extremes of social behavior: the most responsive (black dotted) and the least (red). Sensitivity analysis in (a) considered a fixed sense of safety \(d_V=0\), and in (b) considered a fixed level of caution \(d_I=500\).
