Postexposure prophylaxis (PEP) consists of a dose of human rabies immune globulin (HRIG) and rabies vaccine given on the day of the rabies exposure, and then a dose of vaccine given again on days 3, 7, and 14. For people who have never been vaccinated against rabies previously, postexposure prophylaxis (PEP) should always include administration of both HRIG and rabies vaccine. The combination of HRIG and vaccine is recommended for both bite and non-bite exposures, regardless of the interval between exposure and initiation of treatment.

People who have been previously vaccinated or are receiving pre-exposure vaccination for rabies should receive only vaccine.

Adverse reactions to rabies vaccine and immune globulin are not common. Newer vaccines in use today cause fewer adverse reactions than previously available vaccines. Mild, local reactions to the rabies vaccine, such as pain, redness, swelling, or itching at the injection site, have been reported. Rarely, symptoms such as headache, nausea, abdominal pain, muscle aches, and dizziness have been reported. Local pain and low-grade fever may follow injection of rabies immune globulin.

The vaccine should be given at recommended intervals for best results. Talk to your doctor or state or local public health officials if you will not be able to have your shots at the recommended interval. Rabies prevention is a serious matter and changes should not be made in the schedule of doses. Patient assistance programs that provide medications to uninsured or underinsured patients are available for rabies vaccine and immune globulin.

People cannot transmit rabies to other people unless they themselves are sick with rabies. PEP will protect you from developing rabies, and therefore you cannot expose other people to rabies. You can continue to participate in your normal activities.
