Trends in coverage following an equity-oriented strategy for introducing new vaccines, Peru, 2004–2022
The strategy increased coverage in the poorest districts initially and, as national coverage grew, regional disparities were eliminated. However, socioeconomic differences persisted, with wealthier children maintaining higher vaccination rates throughout the study. To eliminate these disparities, geographic targeting should be complemented with household-level targeting.
