The problem with live virus vaccines is that it actually GIVES them a small dose of the actual disease, and they will be carriers / shedders of the virus. Our state vet told me to never use anything but killed virus with chickens, unless your flock already HAS the disease, and you need to build immunity to cut losses in your other birds....
Mareks vaccine does not shed bird to bird, I called Fort Dodge and asked......... neither does the Schering Plough LT-IVAX.

True.
And the virus is live and weakened so that the birds can build an immunity to it.
You can also give any age bird the vaccine, it does not have to be a day old chick.
The reasoning behind the instructions stating "give to day old chicks" is because every day the chick does NOT have the vaccine, they have a greater risk of being exposed to Mareks in the environment.
I have vaccinated 2 and 3 year old birds and 2 week old chicks, all in the same day.
The vaccine is cheap, and easy to administer, but once opened, it has to be thrown away and cannot be saved 3 weeks til the next hatch, so I waite until I have 4 or so hatches, and then do them all at once.
The costly part is getting the vaccine shipped, it has to be in a cooler with a gel ice pack..and you do not wanna know how many people in my family have Jeffers Livestock soft sided coolers for a lunch box !!
