What this research studies

You would receive a DNA vaccine targeting parts of the flu virus shared across many strains, given in multiple doses to trigger both blood and mucosal immunity. The vaccine is coated onto tiny gold particles and delivered into the skin with a needle-free MACH-1 "gene gun" that the team is refining to be clinic-ready and easy to use. Previous work showed broad immune responses and protection in animals and nonhuman primates, and this project focuses on improving the device, its reproducibility, and readiness for early human use. Once device manufacturing and safety testing are complete, the team plans to move toward early human testing.

Who could benefit from this research

Good fit: Early human testing would most likely enroll healthy adult volunteers who meet Phase 1 safety criteria and are willing to receive a new needle-free flu vaccine.

Not a fit: People needing immediate protection, pregnant individuals, or those with certain immune disorders may not benefit in the near term because the work is focused on device development and early testing rather than broad rollout.

Why it matters

Potential benefit: If successful, this could enable a painless, low-dose vaccine that protects against many flu strains and helps reduce transmission.

How similar studies have performed: Gene-gun delivery of DNA vaccines has produced protective immune responses in animal studies and some early human work, but broad clinical use is still limited and this project seeks to advance that approach for clinic use.
