What works, what doesn’t work? Researchers uncover the effect of supporting districts to operationalise digital payments for vaccination campaign workers
A motivated and satisfied health workforce is critical for the success of mass vaccination campaigns against diseases like polio. High-quality vaccination campaigns can interrupt disease transmission, especially during and after periods of disrupted health services, such as those caused by the COVID-19 pandemic.
In sub-Saharan Africa, most vaccination campaign healthcare workers (VCHWs) have historically been paid in cash. Cash payments are often plagued by delays in funds disbursement, leakages, theft risks, and limited financial transparency. These challenges can negatively affect vaccination coverage and worker satisfaction.
To address these challenges, many countries are transitioning to digital payment systems, which are perceived as faster, more convenient, traceable, reliable, and easy to implement. Digital financial systems are already being rolled out in countries including Côte d’Ivoire, Ghana, Mali, Congo, and the Democratic Republic of the Congo. Uganda, with a projected population of nearly 41.6 million, had over 30 million registered mobile money customers using e-cash in 2019.
While early rollouts of digital payments have been largely successful, their full impact on vaccination campaign workers had not been systematically evaluated.
From 2021 to 2024, Makerere University (Uganda) and the University of Dakar (Senegal), with support from the Gates Foundation and technical partners including the Solina Group, WHO AFRO, and the Ministries of Health and Finance in both embarked on an important journey of research under the Digital Health Payment Initiatives and Research (DHPI-R) Project in 28 countries in Sub Saharan Africa
To explore the experiences and lessons of polio vaccination campaign healthcare workers (VCHWs), both male and female, during the 2022 oral poliovirus vaccination campaign in Uganda, researchers led by Prof. Peter Waiswa (principal investigator), together with Margaret McConnell, Juliet Aweko, Daniel Donald Mukuye, Charles Opio, Maggie Ssekitto Ashaba, Andrew Bakainaga, and Elizabeth Ekirapa-Kiracho, with support from the Gates Foundation, conducted a study titled “The Effect of Supporting Districts to Operationalise Digital Payments for Vaccination Campaign Workers: A Cluster Randomised Controlled Trial During the 2022 Polio Vaccination Campaign in Uganda.”
This study examined whether supporting districts to implement electronic cash (e-cash) payments, instead of cash, increased e-cash usage and improved vaccine campaign healthcare workers’ (VCHWs) motivation and satisfaction during an oral poliovirus vaccination campaign in 2022 in Uganda.
The mixed method study now published in BMJ Global Health, September 2025 was conducted in 54 districts in Uganda that had set up the government e-cash payment platform by May 2022. It involved healthcare workers supporting the polio vaccination campaign, regardless of direct vaccine contact. This included nurses, clinicians (vaccinators), mobilisers, community health workers (village health team members), recorders, local council representatives, and supervisors. The unit of randomisation was the district, while the unit of enrolment and data collection was the individual worker.
Method and Setting
As part of this study , In November 2022, a total of 54 districts and 2,665 vaccination campaign healthcare workers (VCHWs) were enrolled in the study and randomly assigned to two groups. Intervention districts received training on using the government e-cash platform, including managing user roles, uploading beneficiary data, and generating payment reports.
The control districts received the standard support given to districts during mass vaccination campaigns from the MoH, MoFPED, WHO and other development partners. This support included group training on implementation of payments, provision of vaccination materials and financial aid.
The study collected data on how VCHWs were paid, their motivation, and their satisfaction with the payment method. Overall, 765 VCHWs in intervention districts and 589 in control districts received e-cash payments.
Findings
Mode of payment for the vaccination campaign healthcare workers
Overall, approximately half of the campaign workers, 50.8% (1354/2665) were paid digitally (e- cash), either using mobile money or via the bank (online supple mental table 2). Payment by e- cash was higher among females, 53.9% (656/1215) compared with males, 48.1% (698/1450) and was lowest among campaign workers aged 30–39 years, 48.7% (368/765). E- cash payment was higher in the intervention arm at 57.5% (765/1,330) in comparison to the control arm at 44.1% (589/1,335).
Satisfaction with payment received during the campaign
Only 36.5% (705/1930) of the VCHWs were satisfied with the payment received during the campaign, with satisfaction being slightly higher in the intervention arm, 37.9% (353/931) compared with the control arm 35.2% (352/999) and among females 37.9% (351/925) compared with males 35.2% (354/1005). Satisfaction was lowest among the married workers, 35.7% (575/1611) compared with the other categories.
Timing and completeness of payments
Nearly, all VCHWs were paid after the campaign, 97.6% (1884/1930), with no significant difference between the intervention (98.1%, 913/931) and the control (97.2%, 971/999) arms
Delayed/non- payment was highest among those with no formal education, 34% (17/50) and among community mobilisers, 30.7% (392/1071). The majority (70.6%, 1362/1930) of the VCHWs stated that the payment received met or even exceeded their payment expectation.
Participants also stated that e-cash was convenient, transparent, time-saving, and cost-saving, as it reduced travel and waiting times and minimized informal deductions.
Despite these benefits and support to districts to operationalize digital payments , there was no significant difference in workers’ motivation or satisfaction between the intervention and control groups. The researchers attributed this partly due to challenges associated with both cash and digital payment modes.
Challenges experienced in effecting payments at the district level
Also a number of challenges were uncovered in this study . Challenges with e-cash payments included unanticipated withdrawal charges, unreliable internet networks, and lengthy processes for validating mobile telephone numbers. For example, payments were delayed or not processed when VCHWs’ names did not match the registration details held by telecommunication companies, or when workers did not have phones registered in their names.
One key informant had this to say on challenges around e-cash payments
‘’ There was a general complaint of charges. Remember when they are dispersing funds, they stick to the budget exactly. They are not looking at the charges. And when you are also paying you have to allocate minus the charges. You get the point. So the people would be expecting let’s take an example of 150 000/= and then they get 149 something. So, they would ask, ‘Why are we getting less money?’ So we labored to explain to them that the bank is charging a certain fee to facilitate the e- cash. (KII_West_EPI FP) There were also challenges associated with an unreliable internet network that was necessary to facilitate log ins for approval of payments
On Challenges experienced in effecting payments at the district level ,Key informant interviews with district leaders involved in the payment process identified several bottlenecks during the payment process of the campaign healthcare workers. One of the major e- cash payment challenges was a lengthy process of validating mobile telephone numbers. ensuring that the VCHW’s names matched the registered mobile account names attached to the telephone number provided by the VCHW for receipt of funds.
‘’Unsuccessful validation occurred when the VCHW’s names did not match the registration details held by the telecommunication companies. Payments for such individuals were delayed or not effected at all. Because some of them do not even have the phones, but they are very good at doing the work…Or if they have, then the phone is not registered in their names. We were supposed to bring that database of the community as well and feed them into the system. That became a problem’’. (KII_North_ADHO)
Suggestions to improve use of e-cash payment system
To increase the use of e- cash, the majority of key informants identified continued training of key staff as a critical intervention with subsequent follow- up to ensure payments are well implemented.
‘’We are not yet ready; our capacity hasn’t been built. We have a big knowledge gap regarding the e- cash system here in this district. (KII East CFO) We request for more training to be conversant [with the system], and to discuss the challenges together during that training, as we share the experiences. Where we have challenges, we sit together and see how they can be addressed’’. (KII_Central_CFO)
The participants also expressed the need for feedback mechanisms to allow them to dialogue with the payers in case there was a delay in payment. Additionally, the participants also acknowledged that there was a need to gradually expand adoption of digital payments considering contextual barriers. A hybrid approach would be an alternative, especially in the remote and hard-to-reach districts.
Other suggested solutions include early preparation of campaign health worker databases to allow for the lengthy telephone validation processes, improvement of the internet infrastructure, consistent use of e- cash payments across programmes and inclusion of withdrawal charges when making payments.
Moving forward policy, the researchers recommend the need to support e- payment systems, in order to minimize challenges in the pay ment processes.
‘’Suggestions to improve the e- cash experience include training of personnel in charge of e- cash payments, timely creation of VCHWs databases, expanding e- cash payments across programmes for efficiency and inclusion of withdrawal charges for the digital payments. To ensure the institutionalisation of digital payment interventions across Uganda, several key enablers are essential. These include formal policy integration by the Ministry of Health and Ministry of Finance into operational guide lines and budget frameworks, as well as ongoing capacity strengthening at the district level to enhance digital planning, payroll management and troubleshooting. Reliable infrastructure such as mobile connectivity and access to digital financial services like mobile money must also be prioritised, especially in rural areas. Implementing routine monitoring and feedback systems will be vital for tracking payment timeliness, worker satisfaction and system performance, allowing for continuous improvement. Furthermore, fostering public–private partner ships with telecom providers and payment platforms is critical for cost- effective scaling. With strong political commitment, aligned funding and active community engagement, this model holds the potential for broader national and regional adoption, leading to more efficient and equitable health service delivery’’. The paper concludes on the way forward
The DHPI-R project was commissioned by the Bill and Melinda Gates Foundation (BMGF) to generate evidence on digital payments in Africa. Although inception, conceptualization of the proposal, and grant award were conducted earlier in 2021, the DHPIR project officially started implementing activities in November 2021, up to March 2025. DHPIR is hosted at the School of Public Health, College of Health Sciences at Makerere University and is implemented in Anglophone and Francophone hubs (countries) in Africa. The Anglophone hub is hosted at MAKSPH, while the Francophone Hub is hosted by the University of Dakar (UCAD) in Senegal.
DHP-IR was rooted in the End Polio Game Campaign, championed by WHO-Afro and partners in 28 countries in Sub Saharan Africa, where digital payments was a key strategy for timely and complete payments to campaign workers.
Makerere University School of Public Health, in collaboration with Jhpiego, invites applications for 49 short-term positions under the Scaling the Optimal Use of Multiple ACTs to Prevent Antimalarial Drug Resistance (STOP-AMDR) Project.
The short-term assignments will support data collection in Buikwe and Busia districts, with some national-level activities. Applicants are encouraged to review the requirements for their preferred position before applying.
Makerere University School of Public Health (MakSPH), through the Africa-Europe Cluster of Research Excellence (CoRE) for Preparedness and Response to Pandemics and Shocks, has shared findings from its study of Uganda’s Mpox response with stakeholders in Kasese, Amuru, Nakasongola and Mayuge districts to strengthen district preparedness for future outbreaks.
The Africa-Europe CoRE is a partnership co-led by MakSPH and the Centre for Research on the Epidemiology of Disasters at UCLouvain, Belgium. It brings together universities in Africa and Europe to strengthen research, training and preparedness for pandemics and other public health shocks.
The district-level dissemination meetings, held from 10 to 14 August 2026, brought together more than 100 local government, health and security officials, Village Health Teams, implementing partners and community representatives. The meetings enabled stakeholders to validate the district-level findings, identify practical actions and provide feedback for the study’s final analysis and national dissemination.
Mr. Philliam Jabim shares the Mpox response study findings with participants during the dissemination meeting in Nakasongola District on 12 August 2026.
Uganda confirmed its first two Mpox cases on 24 July 2024 at Bwera Hospital in Kasese District. The Ministry of Health declared an outbreak on 2 August 2024. As documented in the study, the response involved health workers, communities, local governments, security agencies, political leaders, and implementing partners.
In response to the outbreak, a MakSPH research team led by Prof. Rhoda Wanyenze, Dr. Rawlance Ndejjo, Dr. Steven Kabwama and Mr. Douglas Bulafu conducted a study in May 2025 to assess Uganda’s Mpox response, including its policies, interventions, strategies and challenges, and generate lessons to inform recovery and strengthen preparedness for future public health emergencies.
Using purposive sampling, the research team conducted 20 key informant interviews and five focus group discussions in each of the four districts, drawing perspectives from western Uganda in Kasese, northern Uganda in Amuru, central Uganda in Nakasongola and eastern Uganda in Mayuge.

The study, titled Assessment of the Mpox Response in Uganda: Documenting Challenges, Lessons and Innovations to Strengthen Emergency Preparedness and Response Capacities, was funded by the Government of Uganda through the Makerere UniversityResearch and Innovation Fund (Mak-RIF).
“This study is helping us move beyond recounting the Mpox response to identifying the actions that districts and national partners can take before the next outbreak. By validating the findings with stakeholders who led and experienced the response, we are ensuring that the evidence reflects local realities and can inform stronger surveillance, risk communication, coordination and community engagement,” said Mr. Bulafu, who led the MakSPH team during the dissemination meeting in Amuru.
Mr. Douglas Bulafu engages participants during the Mpox response study dissemination meeting in Amuru District on 10 August 2026.
In Amuru, the 10 August meeting brought together over 25 stakeholders from the district health team, political leadership, security agencies, Village Health Teams, implementing partners and the community. On the same day, a second MakSPH team, led by Mr. Keneth Sebukeera and Mr. Filimin Niyongabo, convened stakeholders in Kasese for a parallel validation meeting. The consultations then continued in Nakasongola on 12 August and concluded in Mayuge on 14 August, extending the study’s engagement across all four districts.
Across the districts, stakeholders said the results reflected their experience during the outbreak. They pointed to strengths in leadership, coordination, community engagement and partner support, while also describing gaps in documentation, logistics, diagnostic access, staffing, risk communication, public trust and continuity of essential health services.
They also noted inconsistent implementation of the World Health Organization (WHO) 7-1-7 target, which calls for detecting a suspected outbreak within seven days, notifying public health authorities within one day and completing early response actions within seven days.

In Kasese, stakeholders highlighted gaps in documentation, financial and logistical resources, and human resources. They identified Village Health Teams and grassroots, religious and cultural leaders as important resources for community surveillance and risk communication. They called for stronger collaboration between technical and non-technical leaders, engagement with traditional healers, greater use of local radio for public sensitisation, and better facilitation of district epidemic response teams to reach distant communities.
Amuru participants called for proactive preparedness in the border district, citing misinformation and rumours as barriers to risk communication. They urged timely, accurate information from health workers and other authorities; training in disease surveillance and grant writing to strengthen capacity and resource mobilisation; and compassionate care, psychosocial support and community awareness to reduce stigma and support survivor reintegration.
During the meeting in Nakasongola, stakeholders identified Community Health Workers and Community Health Extension Workers as potential resources for strengthening community surveillance and addressing workforce shortages. Given the district’s position around Lake Kyoga and along the Kampala-South Sudan transit corridor, they also called for stronger documentation, note-taking and reporting, accurate real-time information, closer communication with the Ministry of Health, and collaboration among technical, political, religious and community leaders.
Ms. Eunice Vivian Asingo, Senior Nursing Officer at Nakasongola Health Centre IV, contributes to the discussion during the Mpox response study dissemination meeting in Nakasongola District on 12 August 2026.
Ms. Eunice Vivian Asingo, Senior Nursing Officer at Nakasongola Health Centre IV, called for a permanent, adequately resourced outbreak-management centre to help protect routine services during future epidemics. “We appeal for better facilities to manage epidemics and outbreaks. At Nakasongola Health Centre IV, spaces previously used for outbreak management have been repurposed for other services, and we have limited staff. During the Mpox response, colleagues assigned to manage patients later returned to the general team, creating fear among staff already under pressure,” she said.
In Mayuge, Dr. Basembeza highlighted leadership, coordination and surveillance structures operating from district to community level as important factors in the response. He said the structures enabled the district to receive and respond quickly to community alerts. “Whenever there is a rumour or an alert, we are able to respond. Within 20 minutes, we had a response because of the structure we have,” Dr. Basembeza said.
Based on the findings, the research team recommends increased preparedness financing, stronger community engagement, decentralised diagnostic services through stronger district laboratory capacity, and improved health information and research systems.
Across the four districts, stakeholders reaffirmed that trusted community structures and coordinated action across sectors are essential to strengthening outbreak preparedness.
Every academic year, a new group of students enters Makerere University School of Public Health (MakSPH) with different professional backgrounds, questions and ambitions. For the School, each cohort adds to a growing community of professionals and researchers shaping public health practice, policy and research in Uganda and beyond.
On Friday, 7 August 2026, MakSPH held its orientation for newly admitted students for the 2026/2027 academic year at the MakSPH Auditorium. The orientation introduced students to the School’s academic programmes, leadership, departments, academic administration, student support services and expectations for university life.
For this academic year, ending July 2027, Makerere University admitted more than 370 students to academic programmes hosted at MakSPH. The intake comprised 75 students in the Bachelor of Environmental Health Science, the School’s only bachelor’s programme, 277 across the nine master’s programmes, and 21 across the two doctoral programmes, PhD by Research and PhD by Coursework and Research.
Dean Prof. Rhoda Wanyenze (centre) with MakSPH staff, student leaders and new students during orientation for the 2026/2027 academic year.
The master’s intake includes 103 students in the Master of Public Health by Distance Education, the highest enrolment for the year, followed by 59 in the Master of Public Health Full-Time. The remaining students joined programmes in Biostatistics, Environmental and Occupational Health, Health Informatics, Health Services Research, Monitoring and Evaluation, Nutrition, and Public Health Disaster Management. Together, the programmes reflect the breadth of knowledge and skills needed to address public health challenges and bring together students pursuing further training from diverse professional backgrounds.
Welcoming the new cohort, MakSPH Dean Prof. Rhoda Wanyenze urged students to approach their studies with purpose, discipline, and resilience, and focus on what they would be able to do with the knowledge and skills they acquire.
“Please find time to enjoy your journey. I know you’re looking ahead to exams and so many other pressures, but let this journey also be one that you enjoy in terms of what you learn and how you grow, so that you leave here better, not because of the paper that you took but because of the capability that you pick up during your time with us.”
MakSPH Dean Prof. Rhoda Wanyenze addresses new students at orientation for the 2026/2027 academic year, 7 August 2026, MakSPH Auditorium, urging them to value capability over paper.
The Dean’s message speaks to the different reasons students are beginning their journeys at MakSPH. For some, the opportunity is to build on professional experience and strengthen their capacity in roles they already hold. Among them is Dr. Judith Nalukwago, a dental surgeon, former 85th Vice Guild President of Makerere University, and Makindye Division III Lord Councillor, who serves as Executive Secretary for Education, Gender and Public Health at City Hall and the Office of the Lord Mayor.
“I am back here to study a Master’s in Public Health. I am very excited. I have a clinical background and have been practising as a clinician, and it has been a joyful experience. But when I joined the journey of leadership, there were challenges because, as Executive Secretary for Public Health in Kampala, we deal with everyday people’s health challenges,” said Dr. Nalukwago, adding:
“Now I am in management and leadership, and that posed a challenge to me as an individual. I asked myself, what course can I do to add to my skills? Where can I gain skills that can help me overcome this challenge while I am dealing with people? And I remembered that we have the School of Public Health at Makerere University.”
Watch: Dr. Judith Nalukwago on why she returned to MakSPH for a Master’s in Public Health:
Her experience during the Ebola response, when she served on the task force, further highlighted the need for broader public health knowledge. She said the training would strengthen her ability to contribute to policy and public health management, particularly in her role at City Hall, where councillors develop policies, bylaws, and ordinances.
For Mr. John Othieno, the motivation is similarly grounded in applying his training to practical problems. A Software Engineering graduate who previously completed a Master’s in Health Informatics at MakSPH, he has returned to pursue a PhD under the Department of Health Policy, Planning and Management. His research focuses on using technology and health informatics to address health-system challenges, including the adoption of picture archiving and communication systems for managing healthcare imaging and data. He said he wants his research to produce solutions that can be applied beyond academia.
“I purposed that, in my academic journey, I would not do research for the sake of having it gather dust on the shelves, but that it would actually be actionable research that can be translated into action, into solutions for our population,” he said.
Watch: Mr. John Othieno on why he returned to MakSPH to pursue a PhD in Public Health:
Nalukwago and Othieno reflect the diverse professional backgrounds that come together at MakSPH, where training, research, and community engagement have been central to the School’s work for over seven decades. Their journeys point to a sustained impact on public health education, seen not only in enrolment and graduate numbers but in the skills and expertise those graduates carry into policy, research, and health systems across Uganda and the region. At the close of the 2024/2025 academic year, MakSPH enrolled 1,140 students across 12 degree programmes, more than 90 percent of them in postgraduate training.
At Makerere University’s 76th Graduation Ceremony on 25 February 2026, MakSPH presented 231 graduates, comprising seven doctoral, 195 master’s and 29 bachelor’s graduates, adding to the health workforce within the region. Among the graduates was Dr. Harriet Aber, who completed her PhD on child substance use in Uganda’s health system and shared her experience with the new cohort during the orientation. She spoke candidly about the demands of postgraduate study and the need to remain positive through its challenges.
Dr. Harriet Aber, a MakSPH PhD graduate, shares her postgraduate journey with new students at orientation, 7 August 2026, MakSPH Auditorium, urging them to maintain a positive attitude through the challenges ahead.
“It’s not a rosy journey. You’re going to have so many moments where you celebrate, where you’re happy about something, but there are also several moments when maybe you’re stuck with the paper, you have to respond to comments, the proposal is not moving, the concept is not clear. Throughout all those processes, one of the things that you just have to maintain is having a positive attitude,” Aber affirmed.
Her experience offered the new cohort a glimpse of the journey ahead, while Prof. Wanyenze’s message focused on how they could make the most of it. The Dean urged students to plan ahead, pursue research opportunities, think independently, and use artificial intelligence responsibly, while seeking mentorship and making full use of the support and opportunities available at the School.
“Our students are our colleagues, and they are our future workmates. Many of them have ended up staying with us. And I know many of you are going to stay with us in the School,” the Dean said, urging students to take seriously the relationships they build with their classmates and faculty, because “we are a network that’s bound together in the same profession.”
