Figure 5. . . . Percentage of measles outbreaks that become large for the indicated models. We considered those outbreaks that are ongoing at the moment of implementation of the vaccination campaign, indicated by the vaccination delay in the x-axis. BVR, baseline vaccination ratio; R0≈16, scenario in which basic reproduction number R0≈16 is considered; R0≈31, scenario in which basic reproduction number R0≈31 is considered; Reff, effective reproduction number.
