Probiotic may restore vaccine power in Antibiotic-Treated babies
NCT ID NCT07189390
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving a probiotic (Infloran®) to infants who received antibiotics in their first month of life can improve their immune response to routine vaccines. Antibiotics can reduce helpful gut bacteria, which may weaken vaccine protection. The trial will compare antibody levels in 360 babies who receive either the probiotic or a placebo, with follow-up through 12 months of age.
