How lung memory T cells protect you after COVID-19 infection or vaccination

The generation and protective function of lung tissue resident memory T cells following SARS-CoV-2 infection or vaccination

NIH-funded research Scripps Research Institute, the · NIH-11291808

Researchers want to see if immune cells that stay in the lungs after COVID-19 infection or vaccination help protect people from future severe lung illness.

What this research studies

This project studies immune "memory" T and B cells that live in the lungs of people who had COVID-19 or received COVID vaccines. You may be asked to give blood and possibly lung samples (for example, bronchoalveolar lavage or other clinical sampling) so the team can measure which immune cells are present and how long they last. The researchers will compare responses from people who recovered from infection with those who were vaccinated and test in the lab how well lung cells recognize virus variants. Some laboratory models will also be used to explore how these lung-resident cells might prevent severe reinfection over time.

Who could benefit from this research

Good fit: Ideal participants are adults who previously had COVID-19 or have been vaccinated and are willing to provide blood and, if needed, lung samples or come to clinic visits.

Not a fit: People who cannot or will not provide samples, children, or those with no history of infection or vaccination may not be eligible and are unlikely to receive direct benefit from participation.

Why it matters

Potential benefit: If successful, this work could help design vaccines or treatments that boost lung-based immunity to lower the risk of reinfection and severe COVID-19.

How similar studies have performed: Prior studies showed long-lived T cell memory in blood after SARS and COVID-19, but demonstrating protective lung-resident T cells for SARS-CoV-2 is still relatively new and not yet well established.
