NIH-funded research R01 grant

How changes in the spike protein of SARS-CoV-2 affect its transmission

Official title: Transmission of CoV-2 and the Impact of Spike Protein Evolution

Funded at Washington University · NIH-10874383 · Data updated 2026-11-12

This study is looking at how different versions of the COVID-19 virus spread from one person to another, using hamsters to see how well the virus can infect them and how their immune systems respond, which could help us understand why the virus keeps changing even with vaccines.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals who have been exposed to SARS-CoV-2 or are at risk of infection, including those with varying immune responses.

Less likely to help

Patients who are not at risk of COVID-19 infection or have already been vaccinated may not benefit directly from this research.

What this research studies

This research investigates how different variants of the SARS-CoV-2 virus, particularly changes in its spike protein, influence the virus's ability to spread among individuals. By using a hamster model, the study aims to quantify the number of virus particles that can successfully infect a host and how the immune responses of both the donor and recipient affect this process. The research will also explore the role of innate immunity in the transmission of the virus, providing insights into how the virus evolves and spreads despite vaccination efforts.

Why it matters

Potential benefit: If successful, this research could lead to improved strategies for controlling the transmission of COVID-19 and its variants.

How similar studies have gone: Other research has shown success in understanding viral transmission dynamics, but this specific approach using barcoded viruses in a hamster model is relatively novel.
