# US states ask USDA to let them vaccinate dairy cattle against bird flu

> State agriculture departments and state veterinarians have asked USDA to approve a voluntary pilot vaccination program for dairy cattle. They say testing and interstate movement restrictions alone are insufficient as bird flu has infected 1,230 dairy herds in 22 states since March 2024; no vaccine is currently licensed.

## Why it matters

Vaccination could help limit disease spread and reduce risks to dairy production, although approval and effectiveness at scale remain uncertain. The immediate feed-market impact is limited, with possible longer-term effects on milk and cattle supply if outbreaks continue or are controlled.
