Can you vaccinate for mareks at 3 months old?

[clayhill]

Hey all, evidently I have mareks in my young flock and wonder if it would do any good to vaccinate them at three months old. It looks like 4 or 5 of eighteen are affected. I plan to separate these in the morning, hopefully I can save the others. Any guess on whether I can save the rest if I vaccinate now? I know the correct procedure is to vaccinate at 1-2 days old. Anyone have any experience with vaccinating later? Anyone have any suggestions for me at all? Any help would be greatly appreciated.

There was another Mareks thread recently where the pathologist that did the necropsy on the Mareks infected birds suggested vaccination with Serum 3. I believe it was said that giving Serum 1 would spark Mareks symptoms in birds infected, but not yet showing symptoms. You might be best off contacting your State Veterinarian first thing on Monday for expert advice on this situation and direction on where you might get the aforementioned vaccine. Mareks has some pretty serious implications for your existing flock as well as any birds you may wish to acquire in the future. Personally, I wouldn't want to be operating on the advice of laymen, but rather the advice of medically trained poultry experts.
