Table 1 IFR: infection fatality rate; VIN: percentage of virus inactivated vaccines; ADV: percentage of adenovirus vaccines; RNA: percentage of RNA vaccines20,21,22,23,24,25; \(T_D\): decoupling time; % Nat-Inf: percentage of population naturally infected at \(T_D\); % Vac: percentage of the population fully vaccinated at \(T_D\); cHIT (conditional herd immunity threshold): percentage of immunized population due to vaccines and natural infections at \(T_D\). The vaccine effectiveness (VE) against SARS-CoV-2 infections was adjusted to 66% for VIN, 73% for ADV and 93% for RNA17,18.
