NASDA and NASAHO asked USDA at a November 5 meeting to authorize a voluntary national emergency vaccination framework for dairy cattle. USDA reported 55 confirmed bird flu cases in cows across seven states from October 5 to November 10, with Washington accounting for 43.
If USDA approves dairy vaccination, it would add a new control tool and could reduce future herd losses and milk output disruption. No immediate price effect is expected because the request is still pending.
After 93 past neutral policy events, Milk (Class III) moved a median -0.0% over 5 sessions (48% higher; middle half -0.6% to +0.6%), and +0.2% over 20.
