We included the medium scenario to provide a
comparison that showed continuation of historic trends,
and to illustrate the potential effect of accelerating
investment plans beyond past trends. The comparison
of figure 4 with figure 7 shows the link between coverage
trajectories and mortality reduction over time. Coverage
would increase less rapidly after 2025 in the high
scenario, which would also be when mortality becomes
flatter. Our analysis showed substantial differences
between the medium and high scenarios. The medium
scenario would prevent 38% of child deaths, 33% of
maternal deaths, and 25% of stillbirths, whereas the
high scenario would prevent 65% of child deaths, 62%
of maternal deaths, and 46% of stillbirths compared
with the low scenario (appendix).
