iMMUNE SYSTEM AFTER BONE MARROW TRANSPLANT

My husband is going for a bone marrow transplant and we are concerned about his immune system after the transplant. We know it will be shot.

Anyone have any suggestions how to protect the immune system/build it up quickly after the transplant? Echinacea, Vitamin C comes to mind. Anything else at all?

We would very much appreciate any suggestions regarding this.
