Bird Flu Vaccines: Poultry Protection and Human Research Status

Poultry: Vaccines exist for specific avian influenza strains (e.g., H5, H7). Used in outbreak control in endemic regions. Efficacy varies by strain match, vaccination protocol, and surveillance. Not universally deployed due to trade restrictions and detection challenges (DIVA strategies needed).

Humans: No licensed vaccine for avian influenza (H5N1, H7N9, etc.). Candidate vaccines in development/stockpiled for pandemic preparedness. Seasonal flu vaccines do not protect against avian strains. Research focuses on broad-spectrum, mRNA, and universal flu vaccines.

Public health measures: surveillance, biosecurity, culling, antiviral stockpiles (oseltamivir), PPE for high-risk workers.
