Pivoting during a crisis: lessons for Emergency Medical Services (EMS) and everyday health systems resilience from the Vaxi Taxi in South Africa
This paper utilizes a five-year embedded research approach to analyze the South African "Vaxi Taxi" initiative, where Emergency Medical Services converted ambulances into mobile vaccination units during the pandemic, demonstrating how adaptive resilience strategies can foster system capacities and creative problem-solving while highlighting the critical, time-intensive nature of building community trust that routine operations often overlook.

When a health system faces a sudden, overwhelming crisis, the usual rules often stop working. In the best-case scenario, the system does not just survive the shock; it bends without breaking, finding new ways to keep people safe. This ability to adapt is called resilience. It is not a fixed trait that an organization either has or lacks, but rather a process that happens every day. It relies on three things working together: the way people think and solve problems, the specific actions they can take, and the web of relationships they have with others. When a crisis hits, these elements must shift quickly. The question for health leaders is not just how to fix a broken machine, but how to help a complex group of people reorganize themselves to handle the unexpected. This is the core challenge explored in a study of how emergency medical services in South Africa responded to the global pandemic.
In the Western Cape province of South Africa, the public ambulance service faced a dilemma that had nothing to do with traffic accidents or heart attacks. As the coronavirus spread, the government needed to vaccinate millions of people, but many were afraid to come to clinics or could not reach them. The ambulance service, whose job is strictly to rush patients to hospitals, found itself at the center of this new problem. They had a fleet of vehicles and a workforce, but they had never run a vaccination program before. The researchers, who worked inside the system for five years, watched as this team of paramedics and managers made a radical decision. They stopped thinking of their ambulances only as transport for the sick and started using them as mobile clinics. They turned the vehicles into "Vaxi Taxis," driving into neighborhoods that were often too dangerous or too remote for standard health workers to enter. This was not a pre-planned strategy; it was a pivot born of necessity, transforming a crisis into an opportunity to rebuild trust with the communities they served.
The story of the Vaxi Taxi began with a fixed vaccination center set up inside a large ambulance workshop in Cape Town. It was a success, but the team realized that staying in one place would not reach the people who needed vaccines the most. They needed to go to the people. However, this shift was not easy. Many of the staff members assigned to the new mobile units were people who had previously been too traumatized to work on the front lines, having suffered assaults or severe stress while doing their regular jobs. For them, the idea of leaving the safety of the station and driving into uncertain neighborhoods was terrifying. There was also deep skepticism from managers who worried that moving vaccines around in ambulances would ruin the cold chain, the strict temperature control needed to keep the shots effective. The system was full of doubt, and the old ways of thinking said this new idea would fail.
To make the Vaxi Taxi work, the team had to do something unusual: they had to unlearn their fears. They did not start by teaching new skills; they started by creating spaces where old fears could be let go. They began by partnering with local community groups who already knew the neighborhoods and could guarantee safety. These trusted partners allowed the ambulance crews to enter areas that were previously off-limits. As the teams drove into townships and rural farms, they did not just drop off vaccines and leave. They walked into community halls, spoke to people in local bars, and listened. This slow, deliberate engagement changed the mindset of the staff. They stopped seeing the community as a threat and started seeing it as a partner. The researchers noted that this shift in thinking was the engine that drove the whole project. It turned a group of scared, demotivated workers into a team that felt a renewed sense of purpose.
One of the most successful examples of this model was in the Cape Winelands district, a vast rural area with small farming towns. Here, the team operated for two years, far longer than the six-month average for other districts. They succeeded because they built a rhythm that supported them. They held weekly meetings where they did not just discuss logistics, but reflected on their feelings and challenges. These sessions became a safe space where staff could say what was hard and figure out solutions together. The team leader gave them the freedom to make their own decisions, trusting them to handle the complexities of the road. This autonomy allowed them to be creative. When they realized that farmworkers were only home late at night, the team stayed up late to vaccinate them. When they had no chairs for a clinic, they borrowed them from a local funeral home or a church. They became resourceful, solving problems with whatever was at hand, a quality the team called "MacGyverism."
The study found that this success was not just about having extra money or new equipment. In fact, there were no new resources for the project. The "slack" in the system—the extra capacity needed to try something new—came from creatively using the people who were already there. The team used staff who were on leave due to injury or trauma, giving them a new role that helped them heal while helping others. This approach suggests that resilience often comes from how well a system can rearrange its existing pieces, not from waiting for new ones to arrive. The Vaxi Taxi also helped repair relationships between the ambulance service and the rest of the health system. For years, ambulance crews had felt isolated and excluded from hospital decision-making. By working together on the vaccination drive, they became part of a larger team, and the gap between them and the hospitals began to close.
However, the researchers were careful to note that this story does not have a perfect ending. While the Vaxi Taxi built strong bonds between the health workers and the community partners, it did not fully solve the deeper problem of building long-term trust with the general public. As the project went on, the teams found it easier to set up clinics in schools and factories than to do the slow, difficult work of organizing door-to-door in the most marginalized neighborhoods. The routine nature of emergency work, which demands speed and efficiency, made it hard to sustain the deep, relational work needed to build lasting community trust. The study suggests that while a crisis can force a system to adapt and find creative solutions, it cannot instantly fix the structural barriers that prevent deep community engagement.
The ultimate lesson from the Vaxi Taxi is that resilience is a practice, not a destination. It is built through the small, daily acts of unlearning old fears, trusting new partners, and finding creative ways to use what you already have. The project showed that when a health system is willing to pivot, it can reach people who were previously invisible. It also showed that the people who do the work are the most important resource, and that giving them the space to think, feel, and solve problems together can turn a crisis into a moment of profound change. The Vaxi Taxi was a temporary response to a pandemic, but the relationships and the new ways of thinking it created may last long after the vaccines are gone.
