University of Calgary researchers are working on a new type of oral Johne's disease vaccine for calves that may provide immunity.

Oral doses are an improvement over an injection of killed vaccine because they can travel to the spot where the offending bacteria are found in the intestine.

"We believe we need a vaccine that can actually get to that site and get into the tissues and start an immune response that would actually be protective," said researcher Jeroen De Buck, of the university's faculty of veterinary medicine.

The vaccine would be given to young calves rather than depending on immunity received in colostrum.

"We don't believe that antibodies transferred from the dam to the calf would be protective," he said.

"We need another kind of response from the calf from in the intestine."

Seventy percent of Alberta dairy farms have Johne's disease.

I'm all for it IF...1. It works, 2. We can get it here. There is an excellent Canadian vaccine for goats and sheep that prevents CL in goats, but one has to have a vet willing to jump thru the hoops to bring it in...
