What this research studies

Rotavirus vaccines protect many children each year, but they don't always work as well, especially in some parts of the world. We believe that the tiny bacteria living in a child's gut, called microbiota, play a big role in how well the vaccine protects them. Our past work shows that these gut bacteria can directly affect the rotavirus and also change the gut lining, making it harder for the vaccine to work. We are working to find out which specific gut bacteria cause the vaccine to be less effective and how they do it.

Who could benefit from this research

Good fit: Children, particularly infants and young children who receive rotavirus vaccines, are the focus of this research.

Not a fit: Patients who are not in the age range for rotavirus vaccination or who do not receive the vaccine would not directly benefit from this specific research.

Why it matters

Potential benefit: This work could help create better rotavirus vaccines or new ways to make existing vaccines more effective for all children.

How similar studies have performed: Previous work by this team and others has shown that gut bacteria can influence how well vaccines work, suggesting a promising direction for this research.
