Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between immunization coverage and disease prevalence has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Kano State where operating conditions differ markedly from more developed markets.

Kano State presents a useful setting for examining this relationship precisely because the conditions there — structural, regulatory, and behavioural — differ from those typically assumed in the broader literature, most of which draws on evidence from more developed economies.

1.2 Statement of the Problem

While immunization coverage is widely discussed in policy and industry circles, empirical evidence on its actual effect on disease prevalence within Kano State remains sparse and, in places, contradictory. This lack of localized, rigorous evidence makes it difficult for decision-makers to know with confidence whether current approaches to immunization coverage are helping or hindering disease prevalence — a gap this study sets out to close.

1.3 Objectives of the Study

1. To examine the effect of Immunization Coverage on disease prevalence in Kano State.
2. To assess the extent to which immunization coverage influences disease prevalence within the study area.
3. To identify the challenges associated with immunization coverage in relation to disease prevalence.
4. To recommend strategies for optimizing immunization coverage in order to improve disease prevalence.

1.4 Research Questions

1. What is the effect of immunization coverage on disease prevalence in Kano State?
2. To what extent does immunization coverage influence disease prevalence within the study area?
3. What challenges are associated with immunization coverage in relation to disease prevalence?
4. What strategies can be adopted to optimize immunization coverage in order to improve disease prevalence?

1.5 Significance of the Study

This study is significant to a range of stakeholders. For policymakers and regulators, the findings offer evidence to guide the design of frameworks that support healthier outcomes around disease prevalence. For managers and practitioners within Kano State, the study provides practical insight into how immunization coverage can be better managed. Finally, it contributes to the academic literature on public health by extending existing knowledge into a specific empirical context, and offers a reference point for future researchers.

1.6 Scope of the Study

The study is limited to an examination of Immunization Coverage and its relationship with disease prevalence within the context of Kano State. It reflects a BSc-level scope of analysis and relies on data and perspectives available within that scope; generalizing the findings beyond this specific context should therefore be done with appropriate caution.
