Summary
This study looked at how bacteria living in the nose and gut affect the immune response to a nasal flu vaccine in 201 children and teens aged 6 to 17. Participants received the vaccine either right away or after a delay, and researchers collected samples to measure antibodies and bacterial changes. The goal was to understand the interaction between these microbes and vaccine effectiveness, not to provide a new treatment.
