Rabies Immune Globulin is used in conjunction with the rabies vaccine to prevent the patient from contracting the rabies infection in the body. It is a dose of the antibodies that your body needs to fight the live rabies vaccination. It is used as passive protection in the period before your body is able to develop its own antibodies. At this point, the patient can fight the infection themselves and will be vaccinated against future infection.
Rabies Immune Globulin can also be given to patients that may have been exposed to a risk of infection to rabies. Patients who have received a bite, lick or scratch from an animal that either has or is believed to be infected with rabies will be given a dose of Rabies Immune Globulin to help the body fight the infection. This process is known as post-exposure prophylaxis, meaning the patient is protected after exposure to the infection.
Infection with the rabies virus is very severe and can often be fatal if left untreated. In the United States, there are several wild animals that can be infected with rabies. These animals include skunks, raccoons, bats or other feral animals. Bites from or contact with these animals account for the vast majority of cases of rabies infection in America. A wide range of animals can be infected with rabies, however. In Canada, the most commonly infected animals are skunks, bats, foxes, dogs, and cats, but horses, pigs, and cattle have also been known to become infected with rabies. In most of the rest of the world, feral dogs pose the highest risk for exposing humans to rabies.
If you are in contact with rabid animals in another country you should get treated immediately. You should then also ensure that you contact your doctor on your return home as you may require additional ongoing treatment.
Rabies Immune Globulin can only be administered under the supervision of a doctor and is available as a solution for injection directly into the muscle of the patient.
