NASDA and NASAHO asked USDA on November 5 to authorize a voluntary national emergency vaccination framework for dairy cattle amid ongoing HPAI outbreaks. More than 1,200 dairy farms across 20 states have reported cases since 2024, and poultry losses have occurred in at least 17 states.
Vaccination could help limit disease spread and reduce risks to dairy and poultry production, but the request is for a framework rather than an approved program, so near-term supply effects are uncertain.
After 22 past neutral disease events, Milk (Class III) moved a median -0.1% over 5 sessions (41% higher; middle half -1.4% to +0.5%), and +0.2% over 20.
