Almost, one third of the world's urban population resides in slums and the number would double by 2030. Slums denotes collection of people from various communities having a meagre income and living in unhygienic conditions thus making themselves most vulnerable for outbreaks of communicable diseases. India contributes substantially to the global disease burden and under-five mortality rates i.e. 20% attributable to vaccine preventable diseases. Immunization plays a crucial role in combating high childhood mortality rates attributable to vaccine preventable diseases across the globe. This systematic review, provides insights on immunization status in slums, identifies various factors influencing it thus, exploring opportunities that may be available to improve vaccination coverage under the National Immunization Program.
Taking into account the above aspects, a review of literature was undertaken in various databases that included studies published between 2006 and 2017.
In India, ~33% of the urban population lives in slums with suboptimal vaccination coverage ranging from 14% to upto 90%. Few of the important causes for low coverage included socioeconomic factors such as poor community participation, lack of awareness, frequent migration, and loss of daily income. Hence, mere presence of vaccines in the National Immunization Program doesn't do the job, there is a definite unmet need to emphasize upon the importance of immunization among slums dwellers and take necessary steps. For instance, delivering immunization services at the doorstep (e.g. pulse polio program), community-based education, text messaging as reminders and incentivized immunization services are some of the opportunities that can be explored and implemented to improve immunization status in the slums.
Thus, in addition to inclusion of more and more vaccines in the National Immunization Program, there is a definite need to focus on people living in high risk areas in order to improve coverage and healthcare indicators.
全球近三分之一的城市人口居住在贫民窟,到 2030 年,这一数字将翻一番。贫民窟是指来自不同社区的收入微薄、生活在不卫生环境中的人群聚居地,因此他们最容易受到传染病爆发的影响。印度在全球疾病负担和五岁以下儿童死亡率方面做出了重大贡献,即 20%的死亡率归因于可通过疫苗预防的疾病。免疫接种在全球范围内对抗可通过疫苗预防的疾病导致的高儿童死亡率方面发挥着至关重要的作用。本系统评价提供了贫民窟免疫状况的见解,确定了影响免疫状况的各种因素,从而探索了在国家免疫规划下提高疫苗接种覆盖率的可能机会。
考虑到上述方面,我们在包括 2006 年至 2017 年期间发表的研究在内的各种数据库中进行了文献综述。
在印度,约 33%的城市人口居住在贫民窟,疫苗接种覆盖率不理想,范围从 14%到 90%不等。覆盖率低的一些重要原因包括社会经济因素,如社区参与度低、缺乏意识、频繁迁移和日常收入损失。因此,国家免疫规划中仅仅存在疫苗并不能解决问题,确实需要强调贫民窟居民免疫接种的重要性,并采取必要的措施。例如,在门口提供免疫服务(如小儿麻痹症强化免疫计划)、以社区为基础的教育、短信提醒和激励性免疫服务,都是可以探索和实施的机会,以改善贫民窟的免疫状况。
因此,除了在国家免疫规划中纳入越来越多的疫苗外,还需要明确关注生活在高风险地区的人群,以提高覆盖率和改善医疗保健指标。
