Could a blood transfusion save kids with severe malaria?
NCT ID NCT05711485
First seen Jun 26, 2026 · Last updated Sep 11, 2026 · Updated 2 times
Summary
This study tests whether giving a whole blood transfusion can help children under 5 with severe malaria and very low platelet counts survive. The trial is enrolling 132 children in Zambia. Researchers will compare death rates and blood changes between those who get a transfusion plus standard care and those who get standard care alone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- whole blood transfusion
- What this could lead to
- If it works, this could provide a simple, low-cost way to save more children from severe malaria.
- What could go wrong
- This is a small, early-stage trial in one country, so results may not apply everywhere. Transfusions carry risks like infection or reactions.
