摘要:This paper attempts to understand the factors of the slow progress in the coverage of basic childhood immunisation in India using three rounds of National Family Health Survey (NFHS) data. States are selected on the basis of changes in full immunisation coverage during 1992-2005. Bivariate, multivariate, and dropout rates are used to understand the differentials and changes in immunisation coverage. The result reveals substantial improvement in partial immunisation in most states; however, the increase in full immunisation coverage has been slower. Two crucial determinants of the full immunisation coverage in selected states are availability of health card and antenatal care (ANC) visits of mother. Further, higher drop out of DPT3 and measles are responsible for slow increase in full immunisation coverage in selected states. The dropout rate between BCG-measles remains very high. The measles vaccination is very poorly addressed in India, due to which full immunisation is low. Mother’s education, standard of living, mass media exposure, and availability of health card are appeared as significant predictor in explaining the full immunisation coverage irrespective of time. Descriptive statistics and multinomial logistic regression analysis are used in the study. Results indicate a steady increase in coverage of full immunisation in last 14 years, while the increase was higher during 1992-1998 but lower during 1998-2005.
