Each scenario increments on a baseline strategy (numbers refer to Table S7 in Text S1). Numbers inside brackets indicate 95% credible intervals.
Baseline 2 refers to vaccination as it occurred before 2000 (risk-based only), and baseline 4 is the post-2000 policy (high-risk group and elderly adult group). For more detail see Text S1.
