Effect of target vaccine coverage rate on total cost and effect. Total cost (right Y-axis) and effect (reduction in diarrhoea events, left Y-axis) as a function of target vaccine coverage rate. Assumptions: vaccine budget, $200,000; 2-dose vaccine efficacy (strategy A), 60%; 3-dose vaccine efficacy (strategy B), 65%; 2-dose vaccine cost per dose (strategy A), $13.00; 3-dose vaccine cost per dose (strategy B), $10.00; target vaccine coverage, allowed to vary.
