In the Democratic Republic of Congo, where an Ebola outbreak has claimed more than 3,000 lives since May 2026, children under five are dying at rates exceeding 60 percent — not always because the virus is more ferocious in small bodies, but because the medicines and trials designed to fight it were not designed with them in mind. The exclusion of children from clinical research is not a new failure; it is a recurring one, repeated across mpox, HIV, tuberculosis, and COVID-19, rooted in the quiet logic that studying adults first is faster and cheaper.

Ebola's Hidden Crisis: Why Children Are Excluded From Life-Saving Treatments
The most vulnerable should not be last in line.
Why does it matter that children are excluded from these trials? Isn't the goal to get any treatment working as fast as possible?
Speed matters, but not at the cost of leaving an entire population without options. If a drug only gets tested on adults, we don't know if it works the same way in children, or what dose is safe. That's not caution—that's a gap.
But the source does say protocols may expand to include children over 20 kilograms. So it's not a permanent exclusion, right?
True, but that's still children over roughly 44 pounds. Kids under six are still out. And the alternative for them—ten days of IV infusions—is described as difficult to administer during an outbreak. That's not really an alternative if it can't be delivered.
The Berlin case with the American doctor's family—did the experimental antibody actually prevent infection?
The source says it's unclear. Four people is too small a sample to know. What we do know is the drug was tolerated well, which is valuable for future research. But we can't claim it prevented anything.
That's the point though. Even that small finding—that a one-year-old could tolerate the drug—becomes useful data. But we're only getting that because of a crisis, not because it was planned.
So what would change if children were included from the start?
Researchers would develop pediatric formulations alongside adult ones. They'd determine safe doses for different age groups. They'd design studies that account for how children's bodies work differently.
And that costs more money and takes more time upfront. The source quotes Marc Biot saying it's cheaper and faster to focus on adults. That's the real barrier.
Is this just an Ebola problem?
No. Russell mentions mpox in 2024, HIV, tuberculosis, COVID-19. It's a pattern. Whenever there's a new disease or drug, children get studied last, if at all.
Though the Global Accelerator for Pediatric Formulations has existed since 2020, so there is some institutional effort to fix this.
There is, but Russell and Le are saying it's not enough. They want children included from day one of any trial, not as a phase-two addition. That's a different standard.
The Pulse
- Children under five are dying of Ebola at rates above 60 percent in the DRC — a toll driven not only by the virus but by the absence of medicines formulated for their bodies.
- The experimental antiviral obeldesivir, currently being trialed in the outbreak zone, excludes children under roughly 12 years old, while the only alternative requires ten days of intravenous infusions — a near-impossible standard in active outbreak conditions.
- A Berlin hospital's decision to treat an American doctor's young children with an experimental antibody drug offered a rare data point: the treatment appeared well tolerated even in infants, but a family of four cannot anchor a clinical conclusion.
- Doctors Without Borders published a formal call in The Lancet demanding that children and pregnant women be built into trial designs from the start — not appended as afterthoughts when the adult data is already in.
- Medical researchers and access advocates are converging on a single argument: when a disease is killing children at catastrophic rates, excluding them from the trials that might save them is not caution — it is a compounded injustice.
In the Democratic Republic of Congo, where an Ebola outbreak has claimed more than 3,000 lives since May 2026, children under five are dying at rates exceeding 60 percent — not always because the virus is more ferocious in small bodies, but because the medicines and trials designed to fight it were not designed with them in mind. The exclusion of children from clinical research is not a new failure; it is a recurring one, repeated across mpox, HIV, tuberculosis, and COVID-19, rooted in the quiet logic that studying adults first is faster and cheaper. What the DRC outbreak makes visible, once again, is that in an emergency, the decision to exclude the most vulnerable from the search for a cure is itself a form of harm.
In the Democratic Republic of Congo, an Ebola outbreak that began in mid-May 2026 has killed more than 3,000 people. For children under five, the mortality rate climbs above 60 percent — and the cause is not always the virus itself. Often, it is the absence of medicines designed for small bodies, and the research systems that decide which patients matter most.
The outbreak involves the Bundibugyo strain of Ebola. In July, researchers launched a study testing obeldesivir, an experimental antiviral meant to protect those exposed to the virus. Children under roughly 30 kilograms — typically 12 years old or younger — were excluded from the trial. The only available alternative, remdesivir, requires ten days of intravenous infusions, a logistical ordeal under any circumstances, and nearly impossible with young children in an active outbreak.
Doctors Without Borders published a commentary in The Lancet in early September arguing that children are not simply small adults. Their metabolisms differ. They may need liquid formulations, different dosing schedules, separate clinical study. Pediatric research costs more and takes longer, so pharmaceutical companies and institutions routinely deprioritize it — studying adults first, adding children later, if at all. Neal Russell, a pediatric physician who led the commentary, notes that young Ebola patients face compounded vulnerabilities: weaker immune systems, harder-to-diagnose symptoms, and treatment environments where they often cannot be accompanied by a parent.
One case offered a rare window into what pediatric emergency treatment might look like. When an American doctor contracted Bundibugyo Ebola in the DRC and was evacuated to Berlin's Charité hospital, his wife and four children were considered at high risk. Doctors chose to treat the family with an experimental antibody drug called MBP134. The children, including a one-year-old, showed no apparent side effects and remained healthy. Whether the drug prevented infection cannot be determined from so small a sample — but the finding that it was tolerated in very young children is a foundation for future research.
The pattern is not new. During the 2024 mpox epidemic in the DRC, a vaccine existed but was not formulated for children. Similar gaps have appeared with HIV, tuberculosis, and COVID-19. The Global Accelerator for Pediatric Formulations network was founded in 2020 precisely because the problem keeps recurring.
Researchers and advocates are now calling for a structural shift: children and pregnant women must be included in clinical trials from inception, not added as an afterthought. In ordinary research, shielding vulnerable populations from experimental risk is sound ethics. In an emergency, that logic inverts — when a virus is killing children at rates above 60 percent, excluding them from trials that might save them becomes its own form of harm. The most vulnerable, Russell argues, should not be last in line.
In the Democratic Republic of Congo, an Ebola outbreak that began in mid-May has killed more than 3,000 people. The disease itself is lethal—roughly half of those infected die. But for children under five, the mortality rate climbs above 60 percent, and the culprit is not always the virus. It is often the absence of medicines designed for their bodies, and the systems that decide which patients get studied first.
The current outbreak involves the Bundibugyo Ebola virus strain. In July, researchers launched the EBO-PEP study to test an experimental antiviral drug called obeldesivir, designed to protect people exposed to the virus. The study excluded children weighing less than 30 kilograms—roughly 12 years old or younger. Protocols may soon expand to include children over 20 kilograms, but those under that threshold, typically six years old or younger, remain outside the trial entirely. For them, the alternative is remdesivir, an antiviral given intravenously. A full course requires ten days of infusions, a logistical nightmare during an outbreak, particularly with young children who cannot sit still or cooperate with repeated needle insertions.
Doctors Without Borders published a commentary in The Lancet in early September calling for children to be centered in Ebola research and prevention. The organization's argument is straightforward: children are not simply small adults. Their metabolisms work differently. They absorb and process medications differently. A dose that works for an adult cannot be scaled down without separate clinical study. Children may need liquid formulations instead of tablets. They may need different dosing schedules. All of this requires additional research, additional cost, and additional time. Pharmaceutical companies and research institutions often treat pediatric studies as a lower priority. It is faster and cheaper to focus on adults first, then add children later—if at all.
Neal Russell, a pediatric doctor in London who consults for Doctors Without Borders and led the Lancet commentary, points to the particular vulnerability of young Ebola patients. Their immune systems are weaker. Underlying health conditions are more common. Diagnosis is harder because early symptoms mimic other illnesses, and young children struggle to describe what they feel. Treatment itself is more demanding. Children require closer monitoring and specially trained staff. Many cannot be accompanied by parents or caregivers into treatment centers, which slows recovery. These are not failures of individual hospitals or doctors. They are structural gaps in how medical research is designed.
In May, an American doctor contracted Bundibugyo Ebola while treating patients in the DRC. He was flown to Berlin's Charite hospital. His wife and four children were considered at high risk after close contact with him. The medical team decided to treat the family prophylactically with an experimental antibody drug called MBP134. Han Ngoc Le, a doctor at Charite involved in the treatment, acknowledged the uncertainty. Data on the drug's effects in children was minimal. But the children faced a known, fatal threat. The family remained healthy, with no apparent side effects. Whether the experimental treatment prevented infection remains unclear—a sample of four cannot be generalized. Yet the finding mattered: the antibody was well tolerated even in one-year-olds and children under twelve. That tolerance is a foundation for future research.
The gap in pediatric medicine is not new and not limited to Ebola. In 2024, an mpox epidemic swept the Democratic Republic of Congo, and children made up a large share of the infected and dead. A vaccine existed, but it was not formulated for children. The WHO advised using it off-label for minors, but children received it later than adults. Similar patterns have emerged with HIV, tuberculosis, and COVID-19. In 2020, the Global Accelerator for Pediatric Formulations network was founded, supported by the World Health Organization, to speed the development of child-friendly medicines worldwide. The network exists because the problem persists.
Russell frames the dilemma clearly: in non-emergency research, protecting children and pregnant women from potential harm of an experimental drug makes sense. In an emergency, the calculation shifts. The risk of the disease itself becomes the competing harm. When a virus is killing children at rates above 60 percent, excluding them from trials that might save them is itself a harm. Marc Biot, access coordinator for Europe at Doctors Without Borders, calls for children and pregnant women to be included in clinical trials from the start, not added as an afterthought. Le agrees. She argues that sub-studies or parallel studies should be designed into trials from inception, not bolted on later. Russell's plea is direct: all people should benefit equally from scientific progress during a health crisis. The most vulnerable should not be last in line. No matter who you are, he says, you should have the same opportunity to access medical products that might save your life.
