The dropout rate is one of the determinants of immunization coverage and program performance, program continuity, and follow-up. The dropout rate refers to the proportion of vaccine recipients who did not finish their vaccination schedules, and it is determined by comparing the number of infants who started the schedule to the number who completed it. It is the rate difference between the first and final dosage or the rate difference between the first vaccination and the last vaccine dropout; thus, it denotes that the first recommended dose of vaccine was received, but that the subsequently recommended dose was missed. In India, immunization coverage has shown significant improvements over the last two decades, but full immunization coverage has remained stagnant at 76.5%, of which 19.9% are partially immunized, and 3.6% are children who have been left out. In India, the Universal Immunization Programme (UIP) is challenged with cases related to dropout in immunization. Although immunization coverage in India is improving, the program is challenged by vaccination dropouts. This study provides an analysis of the determinants of vaccination dropout in India using data from two rounds of the National Family Health Survey. The finding shows that the mother's age, education, family wealth, antenatal care visit, and place of delivery were some of the variables that significantly contributed to reducing the dropout rate of immunization among children. The findings of this paper show that the dropout rate has reduced over a certain period of time. The overall improvement in the rates of dropout and increase in full immunization coverage could be attributed to various policy measures taken in the last decade in India, which brought structural changes with a positive impact on full immunization coverage and its components.
疫苗接种中断率是免疫接种覆盖率、项目绩效、项目连续性及后续跟进的决定因素之一。疫苗接种中断率指未完成疫苗接种计划的受种者比例,通过比较开始接种计划的婴儿数量与完成接种计划的婴儿数量来确定。它是首剂与末剂之间的接种率差异,或是首次接种与最后一次疫苗接种中断之间的接种率差异;因此,它表明已接种了首剂推荐疫苗,但后续推荐剂量未接种。在印度,过去二十年免疫接种覆盖率有显著提高,但全程免疫接种覆盖率一直停滞在76.5%,其中19.9%为部分免疫接种,3.6%为未接种儿童。在印度,扩大免疫规划(UIP)面临与免疫接种中断相关的问题。尽管印度的免疫接种覆盖率在提高,但该项目仍面临疫苗接种中断的挑战。本研究利用两轮全国家庭健康调查的数据,对印度疫苗接种中断的决定因素进行了分析。研究结果表明,母亲的年龄、教育程度、家庭财富、产前检查次数及分娩地点是显著有助于降低儿童免疫接种中断率的部分变量。本文的研究结果表明,疫苗接种中断率在一定时期内有所下降。疫苗接种中断率的总体改善及全程免疫接种覆盖率的提高可归因于印度过去十年采取的各种政策措施,这些措施带来了结构性变化,对全程免疫接种覆盖率及其组成部分产生了积极影响。
