Impact of delaying the start of the epidemic and adopting NPIs. a Effective reproduction number Re (mean and 95% CI) as a function of vaccine coverage at the time when infection is seeded. Colors refer to the scenario of delaying the start of the epidemic to different date. The shaded area in gray indicates Re ≤1. b Cumulative number of infections per 10,000 individuals after 1 simulated year for reference scenario and two vaccination strategies (mean and 95% CI). c Reduction in infections (mean and 95% CI) with respect to the reference scenario. d As a, but for net reproduction number Rt (mean and 95% CI) adopting different intensity of NPIs. e As b, but for the scenario of adopting different intensity of NPIs. f As c, but for the scenario of adopting different intensity of NPIs
