Determinants of persistent COVID-19 vaccine hesitancy : a preliminary study among healthcare providers in Lubumbashi, DR Congo
This preliminary cross-sectional study of healthcare providers in Lubumbashi, DR Congo, reveals that despite a high prevalence of persistent COVID-19 vaccine hesitancy (80.23%), geopolitical influence and limited professional experience are the key independent determinants driving this mistrust.

Vaccines are one of the most powerful tools in modern medicine, capable of stopping deadly diseases before they spread. Yet, even when a vaccine is available and free, many people choose not to take it. This reluctance, known as vaccine hesitancy, is not just about forgetting an appointment; it is a complex mix of doubt, fear, and mistrust that can undermine public health efforts. The situation becomes especially critical when the people who are supposed to lead the way—doctors, nurses, and other medical staff—are the ones who hesitate. If the people trained to understand how diseases work and how vaccines protect us are unsure, it sends a confusing message to the rest of the community. In the Democratic Republic of the Congo, this issue has been particularly persistent, creating a gap between the availability of vaccines and the willingness of healthcare workers to receive them.
In the city of Lubumbashi, researchers set out to understand why this hesitation has not faded away, even four years after vaccines were first introduced. They wanted to know what was keeping medical professionals from getting vaccinated in 2025. The team, led by Peniel Masele-Kyaite and colleagues from local universities, reached out to 86 healthcare providers working in hospitals and clinics across the city. These were not just doctors; the group included nurses, lab technicians, and imaging specialists, though doctors made up the majority of the participants. The researchers asked these workers simple but direct questions about their vaccination status and the reasons behind their choices. They looked for patterns in age, experience, and personal beliefs to see what factors were most strongly linked to the decision to delay or refuse the shot.
The results revealed a striking reality: the vast majority of these medical workers had not received a single dose of the COVID-19 vaccine. Out of the 86 people surveyed, 69, or about 80 percent, were still hesitant. This is a high number, especially for a group of people who deal with sick patients every day. When the researchers asked why, two main themes emerged from the answers. First, many workers did not trust how quickly the vaccines were developed, fearing that the clinical trials had been rushed and might not guarantee safety or effectiveness. Second, a large number of them felt personally safe from the disease. They believed they were unlikely to get a severe case of COVID-19, especially since many had never even been infected by the virus themselves.
However, the story became more nuanced when the researchers looked deeper into the data. They found that the reasons for hesitation were not spread evenly across all groups. The hesitation was most strongly linked to two specific factors: how long a person had been working in healthcare and their feelings about international politics. The study showed that healthcare workers with two years of experience or less were far more likely to be hesitant than their more seasoned colleagues. It seems that as medical professionals gain more years of practice, they become more comfortable with the idea of vaccination. The other major factor was a sense of geopolitical mistrust. Many workers felt that the push for vaccination was driven by foreign governments and pharmaceutical companies rather than by a genuine concern for local health needs. This feeling of distrust appeared to be a powerful barrier, outweighing even the medical training these individuals possessed.
Interestingly, the study found that the type of medical job a person held did not matter much. Doctors were just as likely to be hesitant as nurses or technicians, suggesting that having a higher degree or more technical knowledge did not automatically lead to acceptance. Similarly, gender did not play a significant role; men and women in the study showed similar levels of doubt. The researchers also noted that while some workers mentioned concerns about side effects or the cost of getting vaccinated, these were not the primary drivers once the data was analyzed. Instead, the core issues remained the speed of development, the feeling of personal invulnerability, and a deep-seated skepticism about the motives behind the global vaccination campaign.
The authors of the study are careful to note that this was a preliminary look at the problem, involving a relatively small group of people who volunteered to participate. Because of this, they cannot say with absolute certainty that these findings apply to every single healthcare worker in the region. However, the patterns they uncovered offer a clear direction for the future. The persistence of such high hesitancy among medical staff is a warning sign. If the people who are supposed to be the most trusted sources of health information are themselves unsure, it becomes much harder to convince the public to get vaccinated. The researchers suggest that to change this, hospitals and health officials need to do more than just provide vaccines. They need to address the specific fears of younger, less experienced workers and engage in honest, transparent conversations about the political and ethical dimensions of vaccination. Without rebuilding trust and addressing the feeling that the vaccine is an external imposition rather than a local solution, the hesitation in Lubumbashi is likely to continue.
