Hyperimmune rabies serum (H RIG), also known as antirabies serum, is a medication used to prevent rabies infection after exposure.
It is made from the blood of horses or humans that have been vaccinated against rabies and contains antibodies that can neutralize the rabies virus. HRIG is used along with rabies vaccine as part of post-exposure prophylaxis (PEP) after a potential exposure to rabies.
