Background of the Study
Community health workers (CHWs) are pivotal in extending the reach of immunization programs, particularly in areas with limited access to formal healthcare facilities. In Kano State, CHWs serve as the link between healthcare systems and local communities, providing education, administering vaccines, and ensuring follow-up with caregivers. Their role is critical in improving immunization rates by addressing barriers such as misinformation, logistical challenges, and cultural resistance (Ibrahim, 2024; Adeyemi, 2023).
CHWs are often trusted members of the community and can influence health behaviors through personalized engagement and culturally sensitive communication. They play a significant role in identifying children who have missed vaccinations and facilitating catch-up immunization sessions. Moreover, CHWs are instrumental in collecting data and monitoring immunization coverage, which is essential for effective public health planning and intervention (Chukwu, 2024).
Despite their importance, CHWs in Kano State face numerous challenges, including insufficient training, inadequate supplies, and heavy workloads. These factors can hinder their ability to perform their duties effectively, thereby impacting immunization rates. Strengthening the capacity of CHWs through targeted training programs, improved logistical support, and enhanced community engagement strategies is crucial for optimizing immunization outcomes. Recent evidence suggests that well-supported CHW programs are associated with significant improvements in vaccine coverage and a reduction in vaccine-preventable diseases (Ogunleye, 2025).
This study aims to evaluate the role of community health workers in improving immunization rates in Kano State. By examining the current practices, challenges, and successes of CHWs, the research seeks to provide actionable recommendations for enhancing their effectiveness and, by extension, increasing immunization coverage. The study will integrate quantitative data from immunization records with qualitative insights from CHWs and community members, offering a comprehensive analysis of the impact of CHWs on public health.
Statement of the Problem
In Kano State, immunization rates remain suboptimal in many areas due, in part, to gaps in healthcare delivery. Community health workers are central to addressing these gaps; however, their efforts are often hampered by challenges such as inadequate training, insufficient supplies, and high workloads. These challenges limit the effectiveness of CHWs in reaching underserved populations and ensuring that children receive timely vaccinations (Lawal, 2023).
Furthermore, inconsistent support from the formal health systemand limited opportunities for continuous professional development contribute to variability in CHW performance. As a result, many communities in Kano State continue to experience low immunization coverage, leaving children at risk of vaccine-preventable diseases. The lack of systematic evaluation of CHW programs further impedes efforts to identify and address these challenges effectively. Without targeted interventions to strengthen the capacity of CHWs, the potential of these workers to improve immunization rates will remain underutilized.
This study seeks to address these issues by evaluating the role and impact of community health workers in Kano State. By identifying the barriers that CHWs face and analyzing the correlation between CHW performance and immunization coverage, the research aims to provide evidence-based recommendations for enhancing CHW programs. Strengthening the role of CHWs is essential for improving vaccine uptake, reducing disease outbreaks, and ultimately safeguarding public health in Kano State.
Objectives of the Study
- To assess the role of community health workers in promoting immunization in Kano State.
- To identify challenges faced by CHWs in delivering vaccination services.
- To recommend strategies to enhance the effectiveness of CHWs and improve immunization rates.
Research Questions
- What is the current role of CHWs in immunization efforts in Kano State?
- What challenges impede CHWs from effectively increasing immunization coverage?
- What interventions can strengthen CHW performance in vaccine delivery?
Research Hypotheses
- Effective CHW programs are significantly associated with higher immunization rates.
- Inadequate training and supplies are major barriers to CHW effectiveness.
- Enhanced support and capacity-building interventions will improve CHW performance and immunization outcomes.
Scope and Limitations of the Study
The study focuses on CHWs operating in both urban and rural areas of Kano State. Data will be collected through surveys, interviews, and analysis of immunization records. Limitations include potential self-report bias and differences in CHW program implementation across regions.
