In a world where health disparities persist and data often fails to translate into action, Clara Oguji stands out as a beacon of innovation and results-driven leadership.
A seasoned public health strategist, Clara is renowned for transforming complex health data into life-changing strategies. With over a decade of experience, she has worked on initiatives that have improved access to care, boosted immunization rates, and strengthened health systems across multiple countries.
Her career, defined by a commitment to equity, accountability, and sustainability, has taken her from the rural districts of Nigeria to international platforms advocating for smarter health investments. Yet among her many achievements, it is her recent groundbreaking study on childhood immunization that reflects her deep connection to community health and her passion for driving measurable change.
Groundbreaking Research In Childhood Immunization
Clara’s most recent study, “Childhood Immunization: What Caregivers Know in a Predominantly Urban Area Council in Abuja, Nigeria,” is a landmark contribution to the field of public health. Designed to evaluate the knowledge levels of caregivers regarding vaccine-preventable diseases, immunization schedules, and management of adverse effects, the research employed a cross-sectional survey design. Using the World Health Organization’s two-stage cluster sampling technique, data were collected from 467 caregivers of children under the age of five.
The results were striking. Clara’s analysis revealed that while caregivers showed a commendable understanding of the immunization schedule and common diseases like measles and polio, significant gaps persisted in knowledge about less-publicized conditions such as meningitis, hepatitis, and tuberculosis. Equally concerning was the inconsistent approach to managing adverse events following immunization (AEFI), such as high fevers or breathing difficulties.
“Immunization is one of the most cost-effective public health interventions. But to maximize its impact, caregivers must have the right information—not just about schedules, but about disease symptoms and what to do when something goes wrong,” Clara noted.
The Power Of Access And Education
One of the study’s most significant findings was the link between proximity to healthcare facilities and knowledge of immunization. Caregivers who lived closer to health centers or received antenatal care (ANC) were far more likely to be well-informed. This insight reinforces the importance of integrating immunization education into routine maternal health services and ensuring that access to care is equitable.
Clara’s study doesn’t just diagnose the problem, it offers clear recommendations. Among them: enhance public health education campaigns, integrate immunization education into ANC visits, and strengthen monitoring and evaluation systems to track knowledge levels over time. These are not just theoretical suggestions—they are practical, scalable solutions rooted in the realities of health service delivery.
Leading Change Across Borders
Clara’s influence extends well beyond her research. She has led the monitoring, learning, and evaluation of large-scale initiatives to improve primary healthcare data quality across several Nigerian states. Her efforts have contributed to better-informed policy decisions and more efficient health service delivery.
She has also designed information systems that support workforce development programs, enabling real-time evaluation of training curricula. Her contributions to global health data programs span ten countries—including Uganda, Colombia, Thailand, and Ukraine—where she helped develop monitoring and evaluation frameworks for national health initiatives.
Clara played a pivotal role in the rollout of digital health platforms used for immunization reporting across Nigeria’s 774 local government areas, resulting in a remarkable 40 per cent increase in reporting rates within four years.
Empowering Farmers, Strengthening Livelihoods
Clara’s impact also extends into the agricultural sector, where she developed innovative systems for supporting smallholder farmers. She created a codebook that facilitated the disbursement of financial support to over 1,800 farmers affected by crop loss and helped mobilize over $11 million in private sector funding to improve agricultural livelihoods. She also led the development of monitoring and evaluation guidelines for a visibility and financial inclusion grant designed to benefit local agribusinesses.
Her holistic approach to health and development underscores a central belief: improving health outcomes requires addressing the social and economic conditions that shape people’s lives. Whether enhancing disease surveillance systems or empowering rural communities, Clara’s work is anchored in sustainable development through data and innovation.
A Changemaker For Global Health Equity
Clara represents a new generation of global health leaders—strategic, data-savvy, and deeply committed to equity. Her contributions in policy, research, and program design continue to influence health systems not just in Nigeria, but across continents. Through her work, she is proving that when public health is driven by evidence and compassion, lasting change is not just possible—it’s inevitable.
In a time when the world needs bold solutions to pressing health challenges, Clara remains a guiding voice, shaping the future of healthcare—one data point, one strategy, and one community at a time.
Career And Education
Clara Oguji is a seasoned public health professional with over a decade of experience advancing health systems through data science, program evaluation, and strategic innovation. In her current role as a public health informatics fellow, she develops health information systems and data visualization tools, leading impactful evaluations in countries like Kenya and Malawi. She has contributed to global training curricula and policy and also serves as an executive member of a major data visualization committee.
Previously, she managed monitoring and evaluation efforts for agriculture and health development projects, designed real-time MEL systems, and led large-scale studies across multiple Nigerian states. Her early career roles involved improving HIV/AIDS program data quality and supporting national digital health implementations.
Clara holds a Master’s in Public Health from the University of Benin and a BSc in Biochemistry from Igbinedion University. She also earned a certificate in Data Science and Machine Learning from MIT, cementing her expertise in analytics, machine learning, and public health informatics.
