Digital Payments Boost Vaccination Campaign Efficiency in Uganda
KAMPALA, Uganda —Supporting districts to adopt digital payments can significantly improve the efficiency of mass vaccination campaigns in Uganda, even if the gains do not directly translate into higher worker motivation, a new study by Makerere University School of Public Health (MakSPH) researchers has found.
Published on September 10, 2025, in BMJ Global Health, the study examined how helping districts in Uganda transition from cash-based to electronic payments affected vaccination campaign workers. Conducted in early 2023, some four months after the nationwide oral poliovirus vaccination campaign of November 2022, the research assessed the impact of digitised payments on efficiency, timeliness, and worker satisfaction.
With generous support from the Bill & Melinda Gates Foundation, the study was led by MakSPH researchers Peter Waiswa, Juliet Aweko, Maggie Ssekitto Ashaba, Elizabeth Ekirapa-Kiracho, and Charles Opio, in collaboration with Margaret McConnell of the Harvard T.H. Chan School of Public Health, Daniel Donald Mukuye from Uganda’s Ministry of Health, and Andrew Bakainaga from the World Health Organisation (WHO)–Uganda Country Office.
The study’s Principal Investigator and lead author, Assoc. Prof. Peter Waiswa, a health systems researcher at Makerere University School of Public Health, said while the research was conducted in Uganda, its implications are global. He pointed out that some African countries, such as Côte d’Ivoire, Zambia, Tanzania, and Kenya, are already ahead in adopting digital payment systems, while others still lag behind. The study’s findings, he said, are relevant across these contexts and have already informed the work of global actors such as Gavi, WHO, and the Global Fund, who are now integrating digital payments into their own processes.
“This paper is part of several studies we are conducting, but perhaps the most significant,” said Dr. Waiswa, clearly enthusiastic about the findings. “Another outlines the research agenda for digital payments, emphasising the need for more evidence on whether they improve the quality of immunisation campaigns, ensure timeliness and efficiency, and identify which groups face barriers to their use.”
The study was coordinated by MakSPH in collaboration with a network of partners. In Uganda, these included the Ministry of Finance, the Ministry of Health, the World Health Organisation, several implementing organisations, district authorities, as well as telecommunication companies. Importantly, the involvement of Airtel as a non-traditional actor in the study demonstrated the critical role of private sector engagement, often absent in such collaborations, in generating evidence and advancing digital health solutions, particularly in addressing challenges such as timely payments for health campaign workers.
The November 2022 polio campaign, led by the government of Uganda with support from the U.S. CDC and WHO, targeted 8.7 million children under five with the novel oral polio vaccine (nOPV2). Nearly 72,000 teams, including health workers, Village Health Teams, and Local Council representatives, were mobilised nationwide, administering about 10 million doses despite the temporary exclusion of five districts due to the Ebola outbreak at the time.
Building on the campaign, the researchers conducted an exploratory cluster-randomised trial using a mixed-methods approach across 54 districts in Uganda, where they enrolled 2,665 healthcare workers. Intervention districts were trained to use Uganda’s e-cash platform, a government innovation managed by the Ministry of Finance. Introduced in 2017 and formalised in 2019, the cashless system was designed to digitise urgent government payments, enhance efficiency, and improve transparency. It now complements the Integrated Financial Management System, which, though effective for routine payments, was seen as too slow for time-sensitive transactions, including paying campaign health workers, where timely remuneration is critical for maintaining workforce readiness, sustaining campaign momentum, and promptly addressing public health challenges in the communities served.
Intervention studies usually introduce a treatment or program to a group to observe its effects, and the results are compared with a group that does not receive it. The training during the study addressed the delays, leakages, and administrative bottlenecks common in cash-based systems. Intervention districts received instruction on navigating the government e-cash platform, managing user roles, uploading beneficiary data, and generating payment reports, while control districts maintained standard cash payment procedures, serving as a baseline.
Dr. Juliet Aweko, co-author and Research Associate at MakSPH, said the study was timely, observing that health workers are central to successful vaccination campaigns and delayed payments can demotivate them and compromise campaign effectiveness.
“To make digital payments truly work, campaigns must be planned with the workforce in mind. Government and partners need to ensure funds are disbursed on time, streamline and automate registration and verification, and keep accurate records of health workers and their performance. Making mobile money systems compatible and giving workers real-time updates on their payments would not only build trust but also keep them motivated, ultimately improving turnout and ensuring smoother service delivery,” Dr. Aweko stated.
The study found that electronic cash adoption was significantly higher in intervention districts, where 57.5% of workers were paid digitally compared to 44.1% in control districts. What’s more, digital payments did not delay disbursement, as 97.6% of all workers received payment after campaign completion, regardless of method. Still, workers paid via e-cash consistently described the cashless system as convenient, transparent, and cost-effective, citing reduced travel time, lower personal costs, and fewer security risks.
Today, Uganda’s rapidly expanding digital ecosystem provides ground for scaling up cashless payment systems. The Uganda Communications Commission reports that the country has over 43 million active mobile subscriptions, nearly 88% of the estimated 49 million population. Its latest market report shows 26.1 million active internet users, while mobile money continues to dominate financial transactions with more than 33 million accounts and transaction values growing by over 25% annually, according to reports by the Bank of Uganda as of March 2025. This trend reflects a population increasingly reliant on digital platforms, creating a strong opportunity to embed e-payment systems in health service delivery.
For MakSPH researchers Dr. Waiswa and Dr. Aweko, the study evidence confirms that digital payments are both feasible and practical for strengthening the delivery of mass campaigns in low- and middle-income countries like Uganda. With relatively modest support, districts can adopt e-cash systems, providing a scalable model for the health sector. This approach, they suggest, would streamline compensation, reduce administrative delays, and provide a stronger basis for integrating digital payments into future immunisation drives and other public health interventions in the country, thereby strengthening our health systems.
The researchers further emphasised that digitising campaign payments reduces transaction costs and minimises leakages, enabling more funds to reach frontline workers quickly. E-cash also simplifies logistics, strengthens accountability, and enhances financial tracking in health campaigns. These advantages, they found, directly align with the global effort to advance digital transformation in health systems and ensure reliable, transparent worker compensation. The implications also extend beyond just polio, as Uganda continues to rely on mass campaigns for routine immunisation and other outbreak responses, such as measles and yellow fever, where digital payments could improve the efficiency of scarce health resources.
Still, the study acknowledged barriers that could hinder full adoption of a cashless system. Some districts lacked the technical capacity to operate the government’s e-cash platform, upload beneficiary data, and manage user roles. Connectivity issues, limited digital literacy among staff, and occasional system downtimes further disrupted implementation. Additionally, many campaign workers lacked national identity cards or mobile money accounts, making them ineligible for digital payments. To address these challenges, the researchers, among others, recommend targeted capacity building for district finance and health teams, expanded identity and mobile registration for campaign workers, improved internet connectivity, and integration of e-payment systems into routine health planning.
The Makerere University College of Health Sciences (MakCHS) on July 10, 2026, welcomed senior six science students from Ngora High School and Wiggins Secondary School to an inspiring Career Fair aimed at guiding them on careers in health sciences and introducing them to the wide range of academic programmes offered by the College.
The event brought together students pursuing Physics, Chemistry, Biology (PCB) and Biology, Chemistry, Mathematics (BCM), providing them with a unique opportunity to interact with the College leadership, tour laboratories and teaching facilities, and learn first-hand about careers in medicine and other health science disciplines.
Welcoming the students, the College Principal, Prof. Bruce Kirenga, described the College of Health Sciences as one of Africa’s oldest and most distinguished medical schools, with a legacy spanning more than a century.
“We started in 1924, making us one of the oldest medical schools on the continent. You have made the right decision to visit Makerere, and we are delighted to welcome you,” he said.
Prof. Kirenga commended the school administrators and teachers for organizing the visit, noting that exposing learners to university environments early helps them make informed career choices. He explained that the College introduced the Open Day concept after receiving numerous requests from schools seeking career guidance visits.
He congratulated the students for choosing science subjects, describing science as the foundation for solving society’s most pressing challenges.
“You have already made one of the most important decisions by choosing to become scientists. Even more importantly, you have chosen life sciences—a field dedicated to preserving and improving life,” he remarked.
The Principal emphasized that careers in life sciences extend far beyond medicine, encouraging students to remain open-minded as they consider their future.
“Everything that has life requires professionals to keep it healthy—from human beings and animals to crops and the environment. The opportunities are immense, including agriculture, veterinary medicine, biomedical sciences, public health and many other emerging fields.”
He also advised students not to limit themselves to only one academic programme during university applications, recalling instances where highly qualified students narrowly missed admission because they selected only one course.
“Remain open to the opportunities available. Medicine is an excellent profession, but there are many other programmes that are equally rewarding and are shaping the future of healthcare and scientific innovation,” he said.
Prof. Kirenga further encouraged the students to embrace lifelong learning, reminding them that scientific knowledge remains valuable regardless of the career path they eventually pursue.
Addressing the students, the Dean of the School of Medicine, Prof. Annette Nakimuli, acknowledged the growing competition for admission into medical programmes and urged learners to work hard while keeping an open mind about the diverse opportunities available within health sciences.
She explained that admission into the Bachelor of Medicine and Bachelor of Surgery (MBChB) programme has become increasingly competitive due to the rising number of high-performing applicants.
“This year we witnessed unprecedented competition for government sponsorship, with many applicants scoring triple A at Advanced Level and outstanding grades at Ordinary Level. That tells you that you must prepare yourselves to excel academically,” she said.
Prof. Nakimuli noted that while many students aspire to become medical doctors, the health sector today offers numerous innovative programmes that are equally important.
“There are many programmes that parents, teachers and students are still not familiar with. Biomedical Engineering, for example, is one of the exciting fields driving the future of healthcare, yet many students overlook it because they focus only on medicine.”
She encouraged students to explore emerging disciplines that combine medicine, engineering, technology and research, noting that the future of healthcare increasingly depends on multidisciplinary professionals.
The Dean also introduced students to the structure of the School of Medicine, explaining that it comprises twelve academic departments and two specialised units covering a broad spectrum of clinical disciplines, including Internal Medicine, Surgery, Obstetrics and Gynaecology, Orthopaedics, Ophthalmology, Ear, Nose and Throat (ENT), Family Medicine, Anaesthesia and Critical Care, among others.
She explained that students are trained by specialists across these disciplines to become competent general practitioners before pursuing further specialization.
Prof. Erisa Mwaka, the Chair of the Department of Human Anatomy, shared with the students about the School of Biomedical Sciences (SBS). He said the school is one of the four schools that make up the Makerere University College of Health Sciences (MakCHS). As the foundation of medical education, the School provides students with a comprehensive understanding of the biological and molecular sciences that underpin modern healthcare, disease prevention, diagnosis and treatment.
The School comprises several departments, including:
