Dairy cows can build immunity to HPAI, according to latest research

New research shows that dairy cows develop an immunity to high path avian flu after initial infections.

The breakthrough comes after cows exposed through an initial infection showed signs of protection against a secondary exposure.

Cows exposed for a second time showed no signs of disease. Their milk production remained steady and the virus was undetectable.

Researchers at the University of Saskatchewan say that their study suggests a vaccine could be highly effective in managing outbreaks, but they say that more research is needed, noting differences between infection and vaccination.
