Figure 3. DHS and model estimates of age-specific vaccination coverage.

Proportion vaccinated by age in (A) Ghana, (B) Madagascar, and (C) Sierra Leone. Points connected by solid lines are the window-smoothed (age ±5 mo) estimates of vaccine coverage as measured by the most recent DHS survey (blue), as predicted by naïve application of WHO coverage estimates (green), and as fit using our approach (red) in a population with the same age distribution as the DHS data. Shaded regions represent 95% confidence intervals on the window-smoothed estimate calculated as described in Methods.
