Extended Data Fig. 6: Epidemic evolution with adaptive vaccination for different constant values of \({\cal{R}}_0\).

Time evolution of the epidemic, with adaptive vaccination, when different constant values of \({\cal{R}}_0\), namely \({\cal{R}}_0 = 1.27\) (purple), \({\cal{R}}_0 = 1.1\) (orange), \({\cal{R}}_0 = 0.9\) (blue), are assumed, associated with different variants and/or containment strategies. The adaptive vaccination speed is inversely proportional to the size of the epidemic, that is to the number of infection cases. a, Time evolution of the fractions of susceptibles, vaccinated, infected and recovered, and dead. b, Daily new cases. c, Active cases. d, Hospital occupancy. e, ICU occupancy. f, Daily deaths.
