Effect of vaccine efficacy on total cost and effect. Total cost (right Y-axis) and effect (reduction in diarrhoea events, left Y-axis) as a function of vaccine efficacy. Assumptions: vaccine budget, $195,000; 2-dose vaccine efficacy (strategy A), 75%; 3-dose vaccine efficacy (strategy B), allowed to vary; target vaccine coverage, 75%; 2-dose vaccine cost per dose (strategy A), $13.00; 3-dose vaccine cost per dose (strategy B), $10.00.
