Chapter One — 1.1 Background to the Study

Over the past decade, the relationship between immunization coverage and under-five mortality rate has become a subject of considerable debate among scholars and industry practitioners alike, particularly within the context of Selected Local Government Areas in Nigeria where operating conditions differ markedly from more developed markets.

Selected Local Government Areas in Nigeria 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 under-five mortality rate within Selected Local Government Areas in Nigeria 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 under-five mortality rate — a gap this study sets out to close.

1.3 Objectives of the Study

1. To examine the effect of Immunization Coverage on under-five mortality rate in Selected Local Government Areas in Nigeria.
2. To assess the extent to which immunization coverage influences under-five mortality rate within the study area.
3. To identify the challenges associated with immunization coverage in relation to under-five mortality rate.
4. To recommend strategies for optimizing immunization coverage in order to improve under-five mortality rate.

1.4 Research Questions

1. What is the effect of immunization coverage on under-five mortality rate in Selected Local Government Areas in Nigeria?
2. To what extent does immunization coverage influence under-five mortality rate within the study area?
3. What challenges are associated with immunization coverage in relation to under-five mortality rate?
4. What strategies can be adopted to optimize immunization coverage in order to improve under-five mortality rate?

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 under-five mortality rate. For managers and practitioners within Selected Local Government Areas in Nigeria, 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

In terms of scope, this study confines itself to Selected Local Government Areas in Nigeria, focusing specifically on how immunization coverage relates to under-five mortality rate within that setting. Findings are interpreted within these boundaries rather than as universal claims applicable to every organization or market.
