After being scratched by a cat, rabies vaccine should be injected as soon as possible to avoid rabies virus infection, usually within 24 hours. The full course of rabies vaccination is divided into 2 types: 5-shot course and 4-shot course. 5-shot course requires a total of 5 vaccinations, 1 shot each time, according to the sequence of the 0th, 3th, 7th, 14th and 28th days. 4-shot course, i.e., the 211 program, according to the sequence of the 0th, 7th and 21st days of vaccination, on the 0th day, you need to receive 2 shots, the left and the right upper arm/1 shot, and then another shot on the 7th and 21st days, respectively. If the rabies antibody is detected to be more than 0.5U/ml after the full course of vaccination within 1 month, it is basically less likely to be infected with rabies virus. If you are scratched by a cat for more than 48 hours without rabies vaccination, you may be infected by the rabies virus. The incubation period for being infected by the rabies virus is a minimum of 5 days, usually 2-3 months is common, and more than 1 year in some patients. Patients should perform a soap and water rinse of the wound for 15 minutes and disinfect it with iodophor before rabies vaccination. Appropriate dietary contraindications are required after rabies vaccination, avoiding spicy and stimulating diets, stimulating beverages, and immunosuppressant applications. At the same time need to rest, avoid overwork and strenuous activities.
