Scientists dig into the vaginal microbiome to unlock secrets of recurrent yeast infections
NCT ID NCT04930107
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at 120 Canadian women to understand why some get repeated yeast infections while others don't. Researchers will compare the vaginal yeast and bacteria of women with their first infection, those with recurrent infections, and those with yeast but no symptoms. Participants will receive standard treatments (fluconazole or boric acid) and be followed to see how their microbial communities change. The goal is to learn more about what causes recurrent infections and how treatments affect the vaginal environment.
What this could mean

- Fluconazole and boric acid
- What this could lead to
- If successful, this study could help explain why some women get repeated yeast infections and point to better treatment strategies.
- What could go wrong
- This is a very early, small observational study focused on understanding, not testing a new treatment. It may not lead to direct changes in care.
