a Proportion of outbreaks terminated after 1 year, predicted under different vaccination strategies, when the rate of zoonotic introductions is low (red bars) and high (black bars). The error bars represent the upper and lower bounds of the 95% confidence intervals for each vaccination strategy. b Median number of cases per outbreak predicted under different vaccination strategies, when the rate of zoonotic introductions is low (panel A) and high (panel B). The dashed lines represent the upper and lower bounds of the 95% confidence intervals in the absence of vaccination (“no vaccine”)
