Rabies may occur after rabies vaccination, but the chance of developing rabies is very small. The premise is that the biting dog or animal has developed rabies and is in the acute phase of the disease, and the patient is bitten not only by a mild bite, but also by a large area of the body. In this case, even if the rabies vaccine is administered, rabies is likely to occur. In addition, if the rabies vaccine is injected within a relatively long period of time, for example, not within 24 hours, but after 1-2 days or even a week, the rabies virus has already invaded the human body, and rabies vaccine may also develop at this time.
