Must be noticed that plants are not animals. Animals have immune systems; plants deploy defensive responses. Talking about immunity in plants is a nonsense. Plants don't have blood, therefore they don't have white blood cells or are able to make its own antibodies. Plantibodies [1] only work in animals. Most of the time, they just seal the attacker for a while in a tomb of resin and keep with its normal chores. [1] plant substances modified genetically to work the same as antibodies when inoculated into an animal (or to act as precursors or helpers to build antibodies in the same scenery). You could then mass produce antibodies for healthcare system in crops and fields. The problem is that plants can produce allergies and you don't want both actors in the same room.
