NASDA and NASAHO urged the USDA to authorize a voluntary national emergency vaccination framework for dairy cattle as part of a broader response to ongoing HPAI outbreaks. Since the virus first spread from wild birds to dairy cattle in 2024, more than 1,200 dairy farms across 20 states have had confirmed cases.
Vaccination could help limit disease spread and protect dairy herds and milk production, reducing the risk of supply disruption. The request does not report an approved vaccine or an immediate change in supply, so the price impact is uncertain.
After 22 past bullish disease events, Milk (Class III) moved a median -0.0% over 5 sessions (45% higher; middle half -0.9% to +0.5%), and -2.8% over 20.
