Proper2, I just assumed you were in North America. It would be helpful if you added your country to your member profile so people can give you more relevant advice. In this case, I really have no information to draw on, but my gut feeling is that if your adult rabbits are disease-free, there would be no need to vaccinate fryers headed for butchering.
I do recommend that you practice very strict isolation procedures when bringing a new rabbit into your herd. It could save a lot of heartache!
