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 (HPAI) 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 their study suggests that a vaccine could be highly effective in managing outbreaks. However, they note differences between infection and vaccination and say that more research is needed.
