Socioeconomic-related inequities in child immunization: horizontal and vertical dimensions for policy insights

Our findings show that incomplete immunization is significantly concentrated among children belonging to poorer households. After controlling for the confounding effects of need factors, the inequity is still significantly pro-poor (i.e., horizontal inequity). The decomposition reveals that lower education, lower consumption and rural habitation are the major factors driving the corresponding inequity. Further, the differential effect of the needs between all and the target groups (at least based on education), is observed, however, is not statistically significant enough to realize inequity (i.e., no vertical inequity). Overall, the inequity is being induced via non-need factors. We further find that community health services (like anganwadi) have contributed towards reducing the inequity in child immunization significantly. The paper highlights the policy recommendation that the child immunisation program should target factors driving HI and need to align their distribution in terms of risks exposures.
