Resolution Criteria

This market will resolve to YES if the United States implements an official, government-approved vaccination program for commercial poultry against avian influenza (H5N1 or other strains) that includes the actual administration of vaccines to birds in commercial flocks before the resolution date.

The market will resolve to NO if:

• The U.S. continues to rely exclusively on culling and biosecurity measures without implementing vaccination

• Vaccines remain only conditionally approved without actual deployment in commercial flocks

• Vaccination is only used in limited research trials or pilot programs but not broadly implemented

Resolution will be based on official USDA announcements, regulatory decisions, or credible news reports confirming the implementation of a vaccination program.
