According to the 10-day observation method proposed by the World Health Organization, if you do not die within 10 days after vaccination, you are considered to have passed the safety period, but there are individual differences. After being bitten by a dog, do not take any chances, you need to be vaccinated immediately. Rabies is a fatal disease, and once infected, the mortality rate can reach more than 90%. For dogs of clear origin, a 10-day observation period is required after vaccination. For dogs of unknown origin, it is necessary to look at the incubation period of rabies. Generally, the incubation period of rabies is 1-3 months, and if the vaccine is given at the prescribed time, more than 3 months and the dog is healthy, it is basically regarded as having passed the dangerous period. However, the incubation period for a small number of cases is about 1 year, so a dog bite with only a slight abrasion should not be ignored and the vaccine should be given within 24 hours. It is recommended that after being bitten by a dog, you should immediately go to the hospital for disinfection and vaccination to avoid unnecessary situations due to delayed treatment.
