If a dog bites you after you have received rabies vaccination, you do not need to receive rabies vaccination if you have received full rabies vaccination and have been bitten within six months; if you have been bitten after six months and have not received full rabies vaccination, you will need to receive rabies vaccination according to your condition. 1. If you have been bitten by a pet within half a year and have been injected with 5 shots of rabies vaccine, you don’t need to take rabies vaccine after being bitten by a dog again, because there are enough antibodies in half a year after you have been injected with 5 shots of rabies vaccine, you don’t need to take rabies vaccine again, you just need to clean up the wound in time. 2. If you are bitten by a pet again within six months to one year after the full rabies vaccination, you need to receive two rabies vaccines; if you are bitten by a dog again within three years after one year, you need to receive three rabies vaccines; and if you are bitten by a dog more than three years ago, you need to receive the full rabies vaccine (five shots). 3. Rabies can be categorized into three levels of exposure; primary exposure does not require rabies vaccination, secondary exposure requires rabies vaccination, and tertiary exposure requires rabies virus immunoglobulin injection along with rabies vaccination. Because rabies is almost 100% fatal disease, after being scratched and bitten by pets need to be alert and pay attention to, do not be paralyzed, need to go to the hospital for treatment and treatment, can not be randomly used drugs.
