Barriers to childhood vaccination in urban slums of Pakistan.

Background: The urban slums of Pakistan continue to record low childhood vaccination coverage. It is therefore vital to understand the demand-side barriers to childhood vaccination in the slums to determine the required demand-generation interventions. Aims: To document the demand-side barriers related to childhood vaccination in urban slums of Pakistan and recommend appropriate demand-generation interventions. Methods: We investigated the demand-side barriers to childhood vaccination in 4 urban slums of Karachi, Pakistan, and disseminated the findings to the Expanded Program on Immunization and their partners. Using the findings, we made recommendations for collaborations with the various partners and for the design of demand-generation interventions to address the barriers. We then expanded the scope of the original research through a mapping exercise that gathered information on the vaccination-related research and interventions of the partners and used the information gathered to create a portfolio of activities. We present the demand-side barriers from the original research and the portfolio of demand-generation interventions. Results: The original research showed that 412 (49.0%) children aged 12-23 months, from 840 households, were fully vaccinated. Reasons given for not receiving the recommended vaccinations were mainly related to the fear of side effects, social and religious influences, lack of awareness, and misconceptions about vaccine administration. The mapping of activities revealed 47 initiatives that aimed to generate demand for childhood vaccination in the urban slums of Pakistan. Conclusion: Several stakeholders involved in childhood vaccination in the urban slums of Pakistan act independently, operating programmes that are disconnected. There is a need for better coordination and integration of the childhood vaccination interventions by these partners to achieve the goal of universal vaccination coverage.
