A vaccinated dog that bites a person still needs a rabies vaccination. This is because a vaccinated dog may still carry the rabies virus. There are many reports of rabies deaths in patients after being bitten by a healthy dog, even a vaccinated dog. Therefore, no matter what kind of dog bite you get, you need to immediately squeeze the wound from the proximal end to the distal end to squeeze out as much blood as possible, then rinse with running water for more than 30 minutes, then go to the hospital for further professional disinfection, debridement, and then get the full rabies vaccine. These are the basic treatment steps for every patient after a dog bite, i.e. squeeze, rinse, and vaccinate.
