If you have just received rabies vaccine and are bitten by a dog again within six months, you do not need to receive rabies vaccine again, you just need to rinse the wound at home with soapy water or go to a clinic with a canine wound cleaning solution for more than 20 minutes. When rinsing, you can use sterile cotton swabs to remove the bruises and dirt from the wound, fully rinse it with iodophor, disinfect it with sterile gauze, change the medication every 2-3 days or so, observe the changes in the wound, and pay attention to taking antibiotics, including cephalosporin antibacterial drugs, to prevent wound infection. If the redness of the wound is considered to be caused by infection, the wound will need to be cut open and drained if necessary to promote wound healing. In short, rabies vaccination does not need to be given again within six months, so there is no need to give another injection in this case, only to flush the wound.
