The rabies vaccine should be administered within 24 hours of being bitten by a dog. Antibodies are produced fastest within this time period, but the vaccination is also effective beyond 24 hours and should be administered as soon as possible. The incubation period for rabies is generally about 3 months. Rabies vaccination before the onset of rabies allows the body to produce neutralizing antibodies, which ensures sufficient antibodies in the blood when symptoms appear and provides a preventive effect. Rabies vaccination after a dog bite is more often seen as a 4 shot procedure, requiring 3 inoculations, 2 shots for the first time, one shot 7 days later and a final shot on day 21. Injecting within 24 hours will allow the level of your own neutralizing antibodies to reach an effective amount in the shortest possible time, and the prevention of rabies attacks will be more effective. Injecting later simply delays the production of effective antibodies, producing lower protection from antibodies and reducing the effectiveness of rabies prevention. After rabies vaccination, it is forbidden to eat spicy and stimulating foods, control the consumption of strong tea and coffee, avoid strenuous exercise, overexertion, and prevent colds, etc.
