Infant and child immune responses to influenza and COVID-19

Project 2

['FUNDING_OTHER'] · ST. JUDE CHILDREN'S RESEARCH HOSPITAL · NIH-11507370

Researchers will use tiny blood samples from infants, children, and adults to learn how their immune systems respond to influenza and COVID-19 infections and vaccines.

What this research studies

You may be asked to give a small blood sample so scientists can look at immune cells and their activity across different ages. The team will use advanced lab tests (like RNA sequencing, ATAC‑seq, and single‑cell immune profiling) to read gene activity and chromatin accessibility in those cells. They will compare infants, older children, and adults after infection or vaccination to find patterns that might explain why infants often have different outcomes. Results will be combined with computational analyses to map how the developing immune system reacts to these viruses.

Who could benefit from this research

Good fit: Infants, young children, and adults who have had or will have influenza or COVID-19 infection or vaccination and who can provide small blood samples are the best fit.

Not a fit: People without recent or planned infection/vaccination, or those unwilling or unable to provide blood samples, may not directly benefit from this project.

Why it matters

Potential benefit: Could identify why very young children respond differently to flu and COVID-19 and inform better vaccines or treatments for infants and children.

How similar studies have performed: Previous immune profiling studies have revealed age-related differences in virus responses, but combining ATAC‑seq and single‑cell integrative methods specifically in infants is relatively new.
