Abstract
BackgroundIn 2005, Nigeria adopted the Reaching Every Ward strategy to improve vaccination coverage for children 0–23 months of age. By 2015, Ogun state had full coverage (100%) in 12 of its 20 local government areas, but eight had pockets of unimmunized children, with the highest burden (37%) in Remo North. A participatory action research (PAR) approach was used to facilitate implementation of local solutions to contextual barriers to immunization in Remo North. This article assesses and seeks to explain the outcomes of the PAR implemented in Remo North to understand whether and possibly how it improved immunization utilization.MethodsThe PAR intervention took place from 2016 to 2017. It involved two (4-month) cycles of dialogue and action between community members, frontline health workers and local government officials in two wards of Remo North, facilitated by the research team. The PAR was assessed using a pre/post-intervention-only design with mixed methods. These included household surveys of caregivers of 215 and 213 children, respectively, 25 semi-structured interviews with stakeholders involved in immunization service delivery and 16 focus group discussions with community members. Data were analysed using the Strategic Advisory Group of Experts (SAGE) vaccine hesitancy framework.ResultsCollaboration among the three stakeholder groups enabled the development and implementation of solutions to identified problems related to access to and use of immunization services. At endline, assessment by card for children older than 9 months revealed a significant increase in those fully immunized, from 60.7% at baseline to 90.9% (p < .05). A significantly greater number of caregivers visited fixed government health facilities for routine immunization at endline (83.2%) than at baseline (54.2%) (p < .05). The reasons reported by caregivers for improved utilization of routine immunization services were increased community mobilization activities and improved responsiveness of the health workers. Spillover effects into maternal health services enhanced the use of immunization services by caregivers. Spontaneous scale-up of actions occurred across Remo North due to the involvement of local government officials.ConclusionThe PAR approach achieved contextual solutions to problems identified by communities. Collection and integration of evidence into discussions/dialogues with stakeholders can lead to change. Leveraging existing structures and resources enhanced effectiveness.
Highlights
In 2005, Nigeria adopted the Reaching Every Ward strategy to improve vaccination coverage for children 0–23 months of age
The 2018 Nigeria Demographic Health Survey showed that only 31% of children aged 0–23 months had completed a full course of prescribed routine immunization—with differences across geopolitical zones ranging from 76% in the South East to 5% in the North West [3]
We explored whether immunization utilization had changed and the main drivers of change
Summary
In 2005, Nigeria adopted the Reaching Every Ward strategy to improve vaccination coverage for children 0–23 months of age. By 2015, Ogun state had full coverage (100%) in 12 of its 20 local government areas, but eight had pockets of unimmunized children, with the highest burden (37%) in Remo North. Though the global immunization trends over the years have been positive, diphtheria, tetanus and pertussis (DTP) coverage remained the same from 2015 to 2019 (85%), with about 19.7 million children still vulnerable to vaccine-preventable diseases [2]. Most of those children are found in 10 countries, including Nigeria [1]. The rationale was that using methods that involve iterative processes of reflection and action carried out jointly with communities, health workers and local government officials would likely provide insight into the relevant problems and their realistic, context-specific solutions
