Rabigen SAG2 (live attenuated rabies virus, SAG2 strain) is used for the active immunization of red foxes (Vulpes vulpes) and raccoon dogs (Nyctereutes procyonoides) against rabies. It is administered orally via bait. Rabies is a fatal disease, and vaccinating wildlife, particularly foxes and raccoon dogs, is crucial for controlling the spread of rabies to other animals and humans.
