US state agriculture and animal-health groups urged the USDA to establish a voluntary emergency vaccination framework for dairy cattle, starting with a limited pilot. They said vaccination could complement surveillance, biosecurity and movement controls as H5N1 continues to circulate in dairy herds; infections have been associated with reduced milk production, culling and abortions.
If adopted, vaccination could limit disease-related milk losses and help protect cattle supply, easing the risk of tighter dairy and beef availability. The proposal is not yet a USDA policy or an immediate supply change.
