  • Modular platform supports rapid adaptation for norovirus, COVID-19, flu, and potentially HPV, with favorable safety and tolerability in over 1,100 participants dosed to date.

  • Manufacturing and operations are U.S.-based, supporting domestic production, supply chain resilience, and rapid response.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
