How COVID-19 vaccines and the microbiome shape immune responses

Systems biological assessment of innate and adaptive immunity to vaccination

NIH-funded research Stanford University · NIH-11388579

This project looks at how different COVID-19 vaccines and the gut microbiome change immune responses in adults, including people with serious allergies.

What this research studies

You would be part of work that uses detailed immune testing and microbiome analysis to understand how vaccines trigger protection. The team compares people with serious allergic (atopic) conditions to healthy adults and studies blood and stool samples to map innate and adaptive immune responses. They will analyze samples from a Novavax clinical trial in South Africa and study responses to mRNA vaccines like BNT162b2. Some parts include experiments where the microbiome is altered (for example with antibiotics) to see how that changes vaccine-driven immunity.

Who could benefit from this research

Good fit: Adults (21+) — especially those with serious allergic diseases or healthy volunteers who can give blood and stool samples and/or have received COVID-19 vaccines — are the ideal candidates.

Not a fit: Children under 21, people unwilling to provide biological samples, or those with health issues unrelated to immune or allergic conditions are unlikely to benefit directly from this work.

Why it matters

Potential benefit: Results could help make COVID-19 vaccines safer and more effective for people with allergies and point to microbiome-based ways to boost vaccine responses.

How similar studies have performed: Previous systems-vaccinology and microbiome studies have linked gut bacteria to vaccine responses, but comparing mRNA and Matrix‑M adjuvanted vaccines in people with serious allergies is a newer application of these methods.
