Rabies vaccine boosters need to be avoided for about 40 days. The rabies vaccination cycle lasts 28 days, starting from the first injection of rabies vaccine until 2 weeks after the end of the full course of treatment, during which time the patient should avoid food and drink. Normally, starting from the first booster injection of rabies vaccine, patients should avoid alcohol, strong tea and coffee, and try not to eat beverages and foods that excite the central nervous system, such as chocolate and cola. It is best to avoid all kinds of spicy and irritating foods, such as ginger, raw onion, raw garlic, chili pepper, mustard, and dishes such as spicy hot and boiled fish, and try to eat as little as possible of seafood, fish and shrimp, mutton and so on. At the same time, strenuous activities and heavy physical labor should be avoided, as these may affect the body’s immune system, causing immune dysfunction, which is not conducive to the production of antibodies, and may induce or aggravate the adverse reactions to the vaccine, resulting in a variety of uncomfortable symptoms in the patient. During the period of rabies vaccination, it is recommended to take a light diet, pay attention to rest, and prevent colds.
