Exercise is allowed 2 weeks after rabies vaccination, but should not be too strenuous. Antibodies are not produced immediately after rabies vaccination, but it takes some time before sufficient levels of antibodies are produced to provide effective immune protection. Antibodies are usually produced 7 to 14 days after the first vaccination and remain at a high level for about six months to a year after the entire vaccination, then gradually decline to disappear. The incubation period of rabies is usually 2~3 months, less than a week for a short time and a year for a long time. In the early stage of rabies vaccination, if the antibody level in the body is insufficient, strenuous exercise will accelerate the speed of the virus traveling to the head, thus speeding up the onset of the disease. In addition, strenuous exercise may also increase the probability of adverse reactions to the vaccine. Therefore, it is recommended that patients should not exercise until 2 weeks after rabies vaccination and should not exercise too strenuously. If you experience any discomfort after vaccination, you should seek medical attention.
