Rabies vaccination is given within 24 hours of being bitten or scratched, but if it is more than 24 hours, it is still recommended that it be given as soon as possible. Rabies has an incubation period of approximately 1-3 months. Any rabies vaccination given before the onset of rabies to allow for an effective amount of neutralizing antibodies may serve the purpose of preventing rabies attacks. The rabies vaccine generally requires a total of 5 injections at 0, 3, 7, 14, and 28 days, respectively, and it is at about 7 days (injection #3) that the antibodies reach an effective antibody level and play a more complete role in stopping a rabies attack. The earlier the injection is given within 24 hours, the earlier the level of your own antibodies will reach an effective amount and the more likely you will be able to prevent a rabies attack. If the injection is given later, the time for effective antibody production is simply pushed back, reducing the effectiveness of preventing rabies attacks from occurring. After rabies vaccination, patients need to pay attention to strict taboos, avoid eating spicy and stimulating foods, control the consumption of strong tea and coffee, and avoid strenuous exercise, overexertion and prevention of colds.
