Vaccination Series to Prevent Rabies After Exposure
Rabies vaccination is a series of shots given over a
period of 2 weeks after a possible exposure to rabies. Rabies vaccines contain
inactivated virus particles that increase the body's immune response, which in
turn helps destroy the rabies virus.
Three rabies vaccines have been approved for use in the United
States; all are considered equally effective and equally safe. The vaccines
Polio, an infectious disease caused by a virus that lives in the throat and intestinal tract, was once the leading cause of disability in the U.S. Since the introduction of the polio vaccine in 1955, the disease has been eradicated in the U.S. But the disease is still common in some developing countries and until it is eradicated worldwide, the risk of it spreading to the U.S. still exists. For that reason, the polio vaccination remains one of the recommended childhood immunizations. In most parts...
In the form of a shot, usually in the upper arm

Four times over the
span of 2 weeks. The first shot should be given as soon as possible after
suspected exposure. Additional shots are given on days 3, 7, and 14 after
exposure. A shot of rabies immunoglobulin usually is also given right after exposure.
Local reactions, such as pain, itching, and swelling at the site of
the shot, have been reported after vaccination with each of the three vaccines
available in the U.S. Systemic reactions, such as headache, nausea, abdominal
pain, and muscle aches, are less common.
Newer rabies vaccines used today are not as painful and do not require as many shots as the older vaccines.
