Impact of Measles Vaccination Education on Childhood Measles Vaccination Uptake among Parents in Nigeria

Abstract

Measles remains an important vaccine-preventable disease and public health concern among children in Nigeria. Although effective measles-containing vaccines are available, children may remain vulnerable to measles infection because of incomplete vaccination, missed routine immunization opportunities, limited access to healthcare services, misinformation, vaccine hesitancy, concerns about vaccine safety, and inadequate awareness of recommended vaccination schedules. Parents and caregivers play a central role in ensuring that eligible children receive routine childhood vaccinations. Measles vaccination education provides an opportunity to improve parents' understanding of measles, the benefits and safety of vaccination, recommended vaccination schedules, possible vaccine-related reactions, and the importance of completing required doses. Against this background, this study investigates the impact of measles vaccination education on childhood measles vaccination uptake among parents in Nigeria. The study will be anchored on the Health Belief Model, Theory of Planned Behavior, and Health Belief Theory of Vaccine Hesitancy. The Health Belief Model explains how parents' perceptions of their child's susceptibility to measles, perceived severity of measles, perceived benefits of vaccination, perceived barriers, self-efficacy, and cues to action may influence vaccination decisions. The Theory of Planned Behavior emphasizes parents' attitudes toward measles vaccination, subjective norms, perceived behavioural control, and behavioural intentions as determinants of vaccination behaviour. The vaccine-hesitancy perspective highlights the influence of confidence, complacency, convenience, misinformation, trust, and concerns about vaccine safety on parental vaccination decisions. Collectively, these theoretical perspectives provide a suitable framework for explaining how measles vaccination education may influence childhood measles vaccination uptake among parents in Nigeria. The study will adopt a quantitative quasi-experimental or analytical cross-sectional research design. The study population will comprise parents or primary caregivers of children eligible for routine measles-containing vaccination residing in selected urban, semi-urban, and rural communities across Nigeria. A multistage sampling technique will be used to select geopolitical zones, states, local government areas, communities, households, primary healthcare centres, and eligible parents. Measles vaccination education will be assessed using indicators such as exposure to vaccination education sessions, frequency and duration of education, information about measles transmission and complications, benefits of vaccination, vaccine safety, recommended vaccination schedules, number and timing of required doses according to the applicable national immunization schedule, possible minor post-vaccination reactions, contraindications and precautions where relevant, management of concerns, vaccine misinformation, vaccine-hesitancy issues, and sources of reliable immunization information. Childhood measles vaccination uptake will be assessed using indicators such as receipt of age-appropriate measles-containing vaccine doses, vaccination completion, timeliness of vaccination, missed vaccination opportunities, vaccination-card documentation, immunization-register verification where available, and parental intention to complete outstanding doses for eligible children. Data will be collected using structured questionnaires, standardized vaccination knowledge and uptake assessment tools, child immunization cards where available and ethically accessible, health-facility immunization registers where appropriate, and pre-test and post-test assessments where a quasi-experimental intervention is adopted. Descriptive statistics will be used to summarize parents' demographic and socioeconomic characteristics, children's characteristics, sources of immunization information, vaccination knowledge, and vaccination status. Inferential statistical techniques, including chi-square tests, paired and independent t-tests, correlation analysis, and logistic or multiple regression analysis where appropriate, will be used to determine the impact of measles vaccination education on childhood measles vaccination uptake. Where a quasi-experimental design is adopted, vaccination uptake before and after the educational intervention may be compared with those of a comparison group to determine changes associated with the intervention. Diagnostic tests will also be conducted to assess the reliability, validity, and robustness of the findings. The study is expected to find that measles vaccination education has a significant positive impact on childhood measles vaccination uptake among parents in Nigeria. Parents exposed to structured, evidence-based, culturally appropriate, and practical measles vaccination education are expected to demonstrate greater adherence to recommended vaccination schedules and higher uptake of age-appropriate measles-containing vaccine doses than parents without comparable exposure. Education may improve parents' understanding of measles transmission, potential complications, vaccine benefits and safety, vaccination schedules, and the importance of completing recommended doses. It may also address common misconceptions and misinformation concerning measles vaccination and improve parents' confidence in discussing vaccination concerns with qualified healthcare professionals. Reminder-based education and clear information about where vaccination services are available may further support timely vaccination. However, vaccine supply interruptions, distance to health facilities, transportation costs, long waiting times, misinformation, vaccine hesitancy, religious or cultural concerns, and inadequate access to routine immunization services may limit the effectiveness of education alone. The study therefore expects accessible, sustained, evidence-based, and community-supported measles vaccination education, integrated with reliable immunization services, to contribute significantly to improved childhood measles vaccination uptake among parents in Nigeria. The study is expected to contribute to the literature on measles vaccination, childhood immunization, vaccine education, vaccine uptake, parental health education, vaccine hesitancy, child health, immunization services, health literacy, and public health in Nigeria. The findings will provide useful information to the Federal Ministry of Health and Social Welfare, National Primary Health Care Development Agency, National Primary Health Care Development Agency's immunization programmes, state ministries of health, primary healthcare centres, healthcare workers, community health workers, traditional and community leaders, development partners, parents, and policymakers regarding strategies for improving measles vaccination coverage. The study will also provide evidence-based recommendations for strengthening parent-focused measles vaccination education, improving communication about vaccine safety and benefits, addressing misinformation and vaccine hesitancy, strengthening reminder and follow-up systems, improving access to routine immunization services, reducing missed vaccination opportunities, and developing sustainable community-based interventions that promote timely and complete childhood measles vaccination across Nigeria.
