Two U.S. agricultural organizations asked the USDA to authorize voluntary emergency vaccination of dairy cattle as part of the HPAI response. They say more than 1,200 dairy farms in 20 states have reported cases since the virus began spreading to cattle in 2024, and argue vaccination should supplement testing, biosecurity and movement controls.
If adopted, vaccination could limit disease-related disruption to dairy production and the supply chain, supporting milk supply. No approval or vaccination rollout is reported, so near-term price 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.
