If a patient shows symptoms of a bite, he or she should promptly wash thoroughly with soapy water or saline, usually for 30 minutes, and go to a medical institution or vaccination agency for disinfection with iodophor or alcohol and other treatments. Since antibodies in the body usually weaken over time after rabies vaccination, patients should determine whether they need to receive rabies vaccination again after being bitten according to the time of vaccination: 1. within 3 months: patients who are bitten again within 3 months after receiving the full rabies vaccination usually do not need to receive rabies vaccination again because strong antibodies still exist in the body, and only need to clean and disinfect the wound in time to prevent infection 2. 3-12 months: If a patient is bitten again within 3-12 months after receiving the full rabies vaccination, the rabies vaccination should be given on day 0 and day 3 because the antibodies have been seen to be weakened; 3. more than 12 months: If a patient is bitten again after 1 year from the last vaccination, the rabies vaccine antibodies have completely decayed and the full vaccination needs to be given again. During rabies vaccination, patients should pay attention to the prohibition of drinking alcohol, drinking strong tea and eating stimulating food, which may lead to adverse reactions or reduce the immune effect of the vaccine. The rabies vaccine does not guarantee absolute immunization success, but it can make the possibility of having rabies much less likely. Therefore, if a patient is bitten again, he or she should actively choose treatment measures under the guidance of a physician according to his or her personal situation to avoid delaying the disease. In addition if the wound is too deep a decision needs to be made under the guidance of a physician as to whether a tetanus vaccination is required and generally antibiotic anti-infection treatment is also required.
