How COVID-19 vaccines trigger early immune responses

Official title: Systems biological assessment of innate responses to vaccination

Funded at Stanford University · NIH-11388605 · Data updated 2026-11-12

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

Who could benefit from this research

Could help

Adults aged 21 and older who have received or are willing to receive COVID-19 vaccines and who can provide blood and microbiome samples (including people with serious allergic or atopic conditions).

Less likely to help

Children under 21 and people who cannot provide samples or who are not receiving these types of COVID-19 vaccines would not directly benefit from participating.

What this research studies

Researchers at Stanford will compare immune signals triggered by mRNA COVID-19 vaccines (such as BNT162b2) and a Novavax vaccine that uses the Matrix‑M adjuvant. They will collect blood and other samples from adults, including people with significant allergies, and use systems-biology tools to map innate and adaptive responses. The team will also analyze participants' microbiome samples to see how microbes might influence vaccine immunity. Some samples come from a Novavax-sponsored trial in South Africa while other samples will be collected at participating sites.

Why it matters

Potential benefit: If successful, this work could help make COVID-19 vaccines safer and more effective for different groups of adults, including people with allergies.

How similar studies have gone: Prior systems-biology studies have successfully revealed immune signatures for other vaccines, but applying these methods to mRNA and Matrix‑M adjuvanted COVID-19 vaccines and to people with serious allergies is relatively new.
