The misunderstanding of the 24-hour rabies vaccine is that the rabies vaccine must be injected within 24 hours after being bitten by a dog, otherwise it will be ineffective. However, in fact, it is also possible to give the rabies vaccine more than 24 hours, but the dose of rabies vaccine may need to be increased. And the sooner you fight, the better; the later, the greater the risk. And after vaccination, it is best to go to the hospital to check whether antibodies have been produced in the body to avoid being infected with rabies due to lack of antibodies.
