aPneumococcal polysaccharide vaccine.
bMaximum variation in these parameters did not cause ICER of preferred program to cross $100,000/QALY threshold.
Results presented only for those parameters, ordered from most to least impact, causing the incremental cost-effectiveness ratio (ICER) of the very high intensity vaccination program to cross $50,000 and $100,000/QALY willingness-to-pay thresholds.
