| Comparisona | Percentage difference in average cost per doseb |
|---|---|

| Uganda | -14% (-19, -7.7) |
| Benin | -16% (-23, -7.9) |
| Ghana | -32% (-37, -27) |
| Zambia | -27% (-32, -22) |
| Moldova | -13% (-17, -8.9) |
| Honduras | -18% (-21, -14) |
| Overall | -19% (-32, -4.0) |
aValues calculated from the results of regression Model 5, controlling for all other model parameters except for those described in the comparison
bCalculated as one minus the average cost per dose for the given scenario divided by average cost per dose in comparator scenario (thus, “–50%” would indicate a halving of costs and “50%” would indicate a 50% increase in costs). Values represent posterior means, and values in parentheses represent equal-tailed 95% credible intervals
cMagnitude of change equal to the difference between the 25th and the 75th percentile of the sample distribution for each variable
