Uses for Imovax Rabies
Rabies vaccine is an active immunizing agent used to prevent infection caused by the rabies virus. The vaccine works by causing your body to produce its own protection (antibodies) against the rabies virus.
Rabies vaccine is used in two ways. Rabies vaccine is given to persons who have been exposed (eg, by a bite, scratch, or lick) to an animal that is known, or thought, to have rabies. This is called post-exposure prophylaxis. Rabies vaccine may also be given ahead of time to persons who have a high risk of getting infected with rabies virus. These persons include veterinarians, animal handlers, or travelers who will spend more than 1 month in countries having a high rate of rabies infection, and persons who live, work, or take vacations in wild areas of the country where they are likely to come into contact with wild animals. This is called pre-exposure prophylaxis.
Rabies infection is a serious, and often fatal, infection. In the U.S., rabies in wild animals, especially raccoons, skunks, foxes, and bats, accounts for most cases of rabies passed on to humans, pets, and other domestic animals. In Canada, the animals most often infected with rabies are foxes, skunks, bats, dogs, and cats. Horses, swine, and cattle also have been known to become infected with rabies. In much of the rest of the world, including Latin America, Africa, and Asia, dogs account for most cases of rabies passed on to humans.
If you are being (or will be) treated for a possible rabies infection while traveling outside of the U.S. or Canada, contact your doctor as soon as you return to the U.S. or Canada, since it may be necessary for you to have additional treatment.
This vaccine is to be given only by or under the supervision of your doctor or other health care professional.

You will receive this vaccine while you are in a hospital or clinic. A nurse or other trained health professional will give you this vaccine. The vaccine is injected into the upper arm muscle (deltoid). Very young or small children may have the vaccine injected into the upper leg (thigh) muscle.
If you are a veterinarian, work with animals, or will be going to a country where rabies is common, you are at risk for exposure to the rabies virus. If you are getting the vaccine because you are at risk of being exposed to rabies, you will receive 3 doses on 3 different days within a 1-month period.
If you have already received the vaccine in the past and have been exposed to the rabies virus, you will need to get 2 doses on 2 different days within a 1-month period.
If you have not yet received the vaccine and were exposed to the rabies virus, you will need a total of 5 doses on 5 different days within a 1-month period. You will also receive a shot of rabies immune globulin.
In order for the rabies vaccine to work properly, it is very important that you do not miss any doses. Keep your appointments with your doctor.
Call your doctor or pharmacist for instructions.
