Chapter One — 1.1 Background to the Study

Water, Sanitation and Hygiene (WASH) Interventions has increasingly attracted the attention of researchers, regulators, and practitioners concerned with vaccination uptake. This growing interest reflects the recognition that water, sanitation and hygiene (WASH) interventions does not operate in isolation, but interacts with a wider set of institutional and market conditions found within Selected Microfinance Banks in Nigeria.

Selected Microfinance Banks 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 water, sanitation and hygiene (WASH) interventions is widely discussed in policy and industry circles, empirical evidence on its actual effect on vaccination uptake within Selected Microfinance Banks 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 water, sanitation and hygiene (WASH) interventions are helping or hindering vaccination uptake — a gap this study sets out to close.

1.3 Objectives of the Study

1. To examine the effect of Water, Sanitation and Hygiene (WASH) Interventions on vaccination uptake in Selected Microfinance Banks in Nigeria.
2. To assess the extent to which water, sanitation and hygiene (WASH) interventions influences vaccination uptake within the study area.
3. To identify the challenges associated with water, sanitation and hygiene (WASH) interventions in relation to vaccination uptake.
4. To recommend strategies for optimizing water, sanitation and hygiene (WASH) interventions in order to improve vaccination uptake.

1.4 Research Questions

1. What is the effect of water, sanitation and hygiene (WASH) interventions on vaccination uptake in Selected Microfinance Banks in Nigeria?
2. To what extent does water, sanitation and hygiene (WASH) interventions influence vaccination uptake within the study area?
3. What challenges are associated with water, sanitation and hygiene (WASH) interventions in relation to vaccination uptake?
4. What strategies can be adopted to optimize water, sanitation and hygiene (WASH) interventions in order to improve vaccination uptake?

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 vaccination uptake. For managers and practitioners within Selected Microfinance Banks in Nigeria, the study provides practical insight into how water, sanitation and hygiene (WASH) interventions 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 Microfinance Banks in Nigeria, focusing specifically on how water, sanitation and hygiene (WASH) interventions relates to vaccination uptake within that setting. Findings are interpreted within these boundaries rather than as universal claims applicable to every organization or market.
