Summary

This study tests whether transferring gut microbes from a mother to her baby after a cesarean section can restore the infant's gut microbiome to resemble that of a vaginally born baby. Researchers will give some infants a fecal transplant (containing bacteria or viruses) and compare their gut bacteria to those receiving a placebo or born vaginally. The goal is to see if this early intervention is feasible and can help prevent health issues linked to C-section births.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Fecal Microbiota Transplantation (FMT) and Fecal Virome Transplantation (FVT)
What this could lead to: If successful, this approach could help restore the gut microbiome in C-section babies, potentially reducing risks of allergies, asthma, and other immune-related conditions later in life.
What could go wrong: This is an early-phase feasibility trial with only 80 participants, so results may not be generalizable. The long-term safety and effectiveness of transferring microbes or viruses to infants are not yet known.
