If you are bitten again after eight months of rabies vaccination, the antibodies to the rabies virus exist in your body for about one month after the vaccination. But after eight months, the antibodies have basically disappeared, so there is no immunity to the rabies virus, so you should continue to go to the hospital to inject rabies vaccine, and you should also follow a course of five injections to complete, in order to get effective immunity. In addition, the wound should be disinfected by repeatedly rinsing it with hydrogen peroxide and saline, and then applying tincture of iodine. It is better to expose the wound to the air without dressing.
