Abstract
AIMS: 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. METHODS: Taking into account the above aspects, a review of literature was undertaken in various databases that included studies published between 2006 and 2017. RESULTS: 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. CONCLUSION: 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.
