NCT ID NCT07300462

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This large study tests whether an oral cholera vaccine can also protect children aged 2 to 14 from infectious diarrhea caused by other germs. 6,000 healthy kids will get either the vaccine or a placebo. The goal is to see if the vaccine lowers the number of diarrhea cases, building on earlier hints of broader protection.

What this could lead to

If successful, this vaccine could help prevent common infectious diarrhea in children, reducing illness and antibiotic use.
