Rabies vaccination is a series of shots given over a
period of 1 month 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
are:
A rabies vaccine (HDCV, RVA, or PCEC) is given:
- In the form of a shot, usually in the upper arm
muscle for adults and in the thigh for children. (Shots are never given in the
buttocks because they are not very effective.)
- Five times over the
span of 1 month. The first shot should be given as soon as possible after
suspected exposure. Additional shots are given on days 3, 7, 14, and 28 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.
