MLA Program Manager Health Welfare & Biosecurity, Dr Johann Schröder, said one of the problems with conventional footrot vaccines is that there are 10 variants of the major protective antigen.

"That means if you vaccinate against one strain of the bacterium that causes footrot, it doesn't protect the sheep against the other nine. What...
