Background of the Study
Vaccination is one of the most effective public health interventions for preventing infectious diseases, reducing mortality rates, and controlling disease outbreaks (WHO, 2024). Despite extensive vaccination campaigns, vaccine hesitancy remains a significant challenge in Nigeria, affecting immunization coverage and contributing to disease resurgence (Adepoju & Yusuf, 2024).
Vaccine hesitancy is defined as the reluctance or refusal to vaccinate despite the availability of vaccines. It is influenced by multiple factors, including misinformation, religious and cultural beliefs, distrust in healthcare systems, and concerns about vaccine safety (Bello & Olatunji, 2024). In Nasarawa State, vaccine hesitancy has contributed to low immunization rates, leaving communities vulnerable to preventable diseases such as measles, polio, and meningitis (Ogunyemi et al., 2024).
This study will appraise the extent of vaccine hesitancy in Nasarawa State and analyze its statistical impact on disease prevalence. By understanding the factors driving vaccine hesitancy, the study will provide insights for improving immunization uptake and strengthening public health interventions.
Statement of the Problem
Despite the availability of free vaccines in Nigeria’s Expanded Program on Immunization (EPI), Nasarawa State continues to experience periodic outbreaks of vaccine-preventable diseases. The persistence of vaccine hesitancy threatens public health efforts, undermining herd immunity and increasing disease burden (Adepoju et al., 2024).
Misinformation, particularly through social media and community networks, has contributed to vaccine skepticism. Additionally, past instances of vaccine-related controversies have fueled distrust in immunization campaigns (Bello & Olatunji, 2024). Without addressing these concerns, vaccine coverage may remain insufficient, leading to higher disease prevalence and avoidable health complications.
This study will assess the drivers of vaccine hesitancy in Nasarawa State and quantify its impact on disease prevalence, guiding policymakers in designing more effective vaccination campaigns.
Objectives of the Study
1. To evaluate the prevalence and factors contributing to vaccine hesitancy in Nasarawa State.
2. To analyze the statistical relationship between vaccine hesitancy and the prevalence of vaccine-preventable diseases.
3. To assess the effectiveness of current vaccination campaigns and public health interventions.
Research Questions
1. What are the key factors driving vaccine hesitancy in Nasarawa State?
2. How does vaccine hesitancy affect the prevalence of vaccine-preventable diseases?
3. How effective are public health strategies in addressing vaccine hesitancy?
Research Hypotheses
1. Vaccine hesitancy is significantly associated with lower immunization coverage in Nasarawa State.
2. Communities with higher vaccine hesitancy experience a higher prevalence of vaccine-preventable diseases.
3. Public health interventions aimed at reducing vaccine hesitancy improve immunization uptake.
Scope and Limitations of the Study
This study will focus on vaccine hesitancy in Nasarawa State, analyzing its impact on immunization rates and disease prevalence. Data will be collected through community surveys, hospital records, and government immunization reports.
Limitations may include response bias in self-reported vaccination status, difficulty in accessing data from rural communities, and potential underreporting of disease cases.
Definitions of Terms
• Vaccine Hesitancy: The reluctance or refusal to receive vaccines despite their availability.
• Immunization Coverage: The proportion of a population that has received vaccinations as recommended by health authorities.
• Vaccine-Preventable Diseases: Infectious diseases such as measles, polio, and diphtheria that can be prevented through immunization.
• Herd Immunity: A form of community protection that occurs when a sufficient proportion of a population is immune to an infectious disease, reducing its spread.
