Time series of vaccine coverage, daily incidence, effective reproductive number, and proportion of immune individuals. a Age-specific vaccine coverage over time for strategy 1. The dotted lines correspond the start of epidemic. The inserted table shows the age-specific coverage for the two key time points (the start of epidemic (i.e., December 1, 2021) and the time that the coverage keeps constant (i.e., March 11)). The line corresponds to the mean value, while the shaded area represents 95% CI. b As a, but for strategy 2. c Daily incidence per 10,000 for strategy 1 (mean and 95% CI). d As c, but for strategy 2. e Effective reproduction number Re over time (mean and 95% CI) for strategy 1. The shaded area in gray indicates the epidemic threshold Re =1. The numbers around the shaded area indicate when Re cross this threshold (i.e., January 31) for strategy 1. f As e, but for strategy 2. g Proportion of immune individuals due to either natural infection or vaccination over time for strategy 1. h As g, but for strategy 2
