Ok, so our family is new to the Nigerian family. We got our first couple a little over a year ago. A couple of months ago we bought an entire herd. They have really great bloodlines and we are so excited! We are currently waiting for the CL and CAE test results. They came from negative herds so we should be good! Anyway, I have been doing lots of research on CL especially. And I have been trying to find out if there is a vaccine for CL, without much luck. Until today. My newest Jeffers catalog came in today and there is a CL vaccine for goats in there. Does anyone know anything about this vaccine? Has anyone used it? Thank you all for your help!

From what I understand, this is a vaccine that you DO NOT want to expose your herd to unless you're struggling with CL in your herd. It will interfere with diagnostic tests to test for the disease, meaning that if a healthy animal has been exposed to the vaccine, the test will show positive even if the animal isn't technically "positive". It doesn't work like other vaccines. It doesn't actually prevent the infection, but helps to prevent symptoms of the infection from appearing in a herd that has been exposed to it.
The vaccine is typically only used in herds that have an outbreak already. The tests cannot distinguish between a vaccinated goat and a goat that has actually had CL, so once you start vaccinating, testing is pointless because your whole herd will test positive.
Adverse reactions to the vaccine have also been reported. According to Goat Medicine -- severe milk drop, lameness, anorexia, fever, depression can occur.
Provided you don't buy a goat with CL, it's not that hard to avoid it, especially if you have a closed herd.

I always feel extra good when my answers match Debs. lol
LOL! Deborah and I must have answered at the same time. She's really smart, so I'm glad we had a similar answer for you! ;)

Here's a link to an article at goatworld.com that tells a little bit about the vaccine.
Best wished on all negative tests! :)
