After being bitten by a dog, you should not only wash and clean the wound locally, but also inject rabies vaccine to prevent the spread of rabies because rabies can be spread after being bitten by a dog, and the death rate of rabies is very high, which seriously threatens people’s lives. The rabies vaccination should be enough for 5 shots to be considered a full immunization, the specific injection method is a dog bite injection at the time, the 3rd day, the 7th day, the 14th day, the 30th day and another injection, so as to form a full immunization, can effectively prevent the spread of rabies. If the owner of the dog can prove that the dog has been vaccinated against rabies and that it is within the validity period, the dog does not need to be vaccinated against rabies after the dog bites the person.
