Summary

This early-stage trial tested whether taking capsules containing healthy gut bacteria (from donated stool) could help people with peanut allergies. Fifteen adults aged 18-40 received the treatment, with some taking antibiotics first. The main goal was to check safety, but researchers also looked for changes in how much peanut protein triggered a reaction. While not a cure, the approach aims to raise the allergy threshold, making accidental exposures less dangerous.
