# As bird flu spreads, dairy industry awaits vaccine

> Bird flu has infected 1,222 US dairy herds in 21 states since March 2024 and has spread to 40 Washington dairies. USDA has not yet licensed a dairy cattle vaccine, though several candidates are in field trials, and a University of Pennsylvania and USDA study reported an immune response in four vaccinated Holstein cows.

## Why it matters

Continued herd infections and movement controls add cost and disruption to milk production, which can support milk prices. A licensed vaccine would ease that pressure over time, but no approval is in place yet.
