Comparison between different vaccination strategies. In (a) and (b), we show the Monte Carlo estimation (over 100 independent simulations) of the cumulative number of infections among adults at the end of the epidemic outbreak, for different values of the fraction of eligible individual vaccinated (V) and different children detection rate (\(q_c\)). In (a), we adopt vaccination strategy I, in which the vaccinated individuals are selected uniformly at random among the adult population. In (b), we adopt vaccination strategy III, in which the vaccination of adults belonging to large families is prioritized. In (c), the two strategies are compared, showing the variation in the cumulative numbers of infections between the two strategies. The parameters used in the simulations are listed in Table 2 and \(q_a=0.25\). All the simulations are done in Scenario III (Alpha variant), with the average infectiousness reported in Table 2
