If a dog bites a person after vaccination, the chances of the person contracting rabies should be relatively small because the dog is immune to the rabies virus after the rabies vaccination, so the dog will generally not be infected with rabies, and the teeth generally do not harbor the rabies virus, so the chances of the person contracting rabies after the bite are very small. However, there are many other bacteria and viruses hidden inside the dog’s teeth, and if the wound is not disinfected and cleaned in a timely manner, it may lead to an infected wound with local redness, swelling, heat, pain, and serious local inflammatory discharge or white pus. So even if a dog is vaccinated and bites a person, the wound must be treated formally, and antibiotics must be applied when necessary as well as tetanus antitoxin injections.
