The World Health Organization (WHO) report, "State of Inequality: Childhood Immunization," addresses two overarching questions: What inequalities in childhood immunization coverage exist in low- and middle-income countries? And how have childhood immunization inequalities changed over the last 10 years?
In answering these questions, this report draws on data about five childhood immunization indicators, disaggregated by four dimensions of inequality, and covering 69 countries. The findings of this report indicate that there is less inequality now than 10 years ago. Global improvements have been realized with variable patterns of change across countries and by indicator and dimension of inequality. The current situation in many countries shows that further improvement is needed to lessen inequalities; in particular, inequalities related to household economic status and mother’s education were the most prominent.
