What this research studies

From your perspective, researchers will collect blood samples from children and adults who receive seasonal flu shots to see how immune memory changes after vaccination. They will also run controlled experiments in rhesus macaques to mimic specific sequences of infection and vaccination. Labs will analyze antibodies, grow individual B cells, isolate monoclonal antibodies, and map exactly which parts of the virus the antibodies target. The team combines these human samples and animal experiments to understand why some exposures give narrow strong protection while others give broader, but weaker, protection.

Who could benefit from this research

Good fit: Ideal candidates are children and adults planning to get a seasonal influenza vaccine who are willing to provide blood (and possibly nasal) samples over time.

Not a fit: People not receiving flu vaccines, those seeking immediate treatment for active influenza illness, or those unable to give biological samples are unlikely to benefit directly from participation.

Why it matters

Potential benefit: If successful, the work could guide vaccines that produce broader and more durable protection against diverse influenza strains.

How similar studies have performed: Prior immunology work on "imprinting" and B cell responses has provided useful insights, but combining detailed human sampling with controlled nonhuman primate experiments is a newer, more integrated approach.
