So I have some questions about the CL vaccine and a scenario that I'd like opinions on. So I'm interested in some does that had the CL vaccine before they were introduced to a herd that has CL. Neither of these does had any history of CL. Some members of the herd they got put into got the vaccine after they've had abscess, some never got the vaccine. If some members of the herd still show active symptoms, would the does who had the vaccine end up getting CL? Would the does who had CL before the vaccine become symptom-free? If these does got quarantined for 21 days then introduced to a new herd of CL-clean does who have never gotten the vaccine, would the new herd have a risk of getting CL?
