State of inequality: childhood immunization
Ideally, children everywhere should have equal access to the benefits of vaccines. However, this is not always the case. In many countries, vaccine coverage varies according to geographical, socioeconomic or demographic factors of the children; patterns of inequality emerge based on characteristics such as their household economic status, mother’s education or place of residence. While some countries have taken action to reduce these types of inequalities, others still have much progress to make. Regular monitoring efforts can help to reveal whether programmes and policies are on track to reach their targets.
