I've been reading various places on the timing of these shots, and I'm getting a bit confused. Some folks give pregnant does a CD/T vaccine prior to kidding and then still vaccinate the kids--and at apparently different ages. Some folks vaccinate pregnant does only and depend on them to pass immunity on to the babies. I'd like some info on this, as I've yet to give my new little herd any vaccines. Isn't there a pneumonia one I should get a hold of, too? What is that, and when should it be given?
