Can a single antibiotic dose cut child mortality in niger?
NCT ID NCT04224987
First seen Aug 06, 2026 · Last updated Aug 07, 2026 · Updated 1 time
Summary
This trial tests whether giving azithromycin—a common antibiotic—twice a year to young children in Niger can reduce deaths. It compares giving the drug to all children aged 1-59 months versus only to infants 1-11 months, who are at highest risk. The study also checks how these approaches affect antibiotic resistance. If targeting infants works, it could save lives while reducing the spread of resistant bacteria.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- azithromycin (an antibiotic)
- What this could lead to
- If successful, this could support a simple, targeted antibiotic strategy to reduce child deaths in high-mortality regions while limiting antibiotic resistance.
- What could go wrong
- The trial is large but still a test—results may not confirm benefit, and antibiotic resistance remains a real risk with widespread use.
