Results of a sensitivity analysis in which the lineage cross protection is varied. For each value, 1,000 simulations with about 80,000 individuals are run for 20 years; 2,000 simulations for the baseline value of 0.6. Average annual number of infections for (a) the TIV scenario and (b) the QIV scenario. (c) Average number of infections prevented per year by QIV. Mean values are connected.
