Outcomes combined into a trade-off. (a) predicted full deaths for baseline scenario with all cases contained inside one region. (b) 'worst' parameters cause the outbreak to be uncontrolled by targeted interventions, leading to preference for national mass vaccination (the massive increase in overall mortality in this case necessitates a different y-axis from other panes). (c) 'best' scenario within the parameters varied changes little. (d) Dispersed trade-off with initial cases maximally dispersed leads to a more severe outbreak but does not qualitatively change the predictions.
