On November 5, state agriculture and animal-health organizations asked USDA to authorize a voluntary national emergency vaccination framework for dairy cattle as part of a broader HPAI control strategy. They cited more than 1,200 dairy farms with confirmed cases across 20 states since the virus first spilled over from wild birds to cattle in 2024.
Vaccination could help limit disease spread and protect milk production, but the proposal is not yet authorized and would not immediately change supply. Its approval could reduce the risk of future dairy supply disruptions.
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.
