Yes there is a vaccine available called Guidair. We have just started vaccinating our goatlings, they need 2 injections starting at 2 months of age. Could be the same for sheep as goats and sheep are similar in the treatment of a variety of diseases. The vaccine has a very good success rate in herds here ( I am in France).I have a mate who was struggling with unexplained high losses in his ewes every year in the run up to lambing. Blood tests at vet never came up with a satisfactory, or likely answer.
18 months ago he bit the bullet and spent some serious coin at the vet school blood testing . Turns out, he has c70% of his ewe flock positive for Johnes.
I think there is some serious testing going on for a vaccine, with good results, but how far from being commercially available it is, no idea
Potentially, but it seems that it's mostly picked up by lambs and young calves through the feacal/oral route in the chronic fatal cases.Does that mean that tack sheep can bring it on to your farm in the wintertime and leave it there for your cattle to pick up in the spring?
cannot / should not vaccinate cattle as it can give false positives on TB test unfortunatelyA vaccine for sheep or cattle?
Thankfully i’ve Never come across it, other than in a couple of bought in dairy cows (it turned out that herd was riddled with it).
