It is not acceptable to give only one dose of rabies vaccine. If only one dose of rabies vaccine is given, the antibodies produced by the body are not enough to fight the rabies virus and the vaccine cannot have the desired effect. Under normal circumstances, the rabies vaccine requires five injections, the first on the day of the dog or cat scratch or bite, and then the second, third, fourth and fifth on the third, seventh, fourteenth and twenty-eighth days, respectively. After five injections are systematically administered, solid antibodies will be produced, which will serve as a defense against rabies. After a complete rabies vaccination, it is usually possible to avoid re-injections for three years, and only one injection will not be effective. In addition, during the rabies vaccination period, you need to pay attention to not eating spicy and stimulating food, not drinking alcohol, strong tea and other stimulating foods, and also pay attention to observe whether there is redness and swelling and red spots and other allergic reactions. If there is an allergic reaction, go to the hospital in time to avoid unnecessary harm.
