Grade I exposure, i.e., only the intact skin has been licked by the animal, can be simply rinsed with water or not treated. Grade II exposure, on the other hand, refers to skin injuries that cause minor breakage but no bleeding. Grade III exposure refers to penetrating skin bites or scratches, or when the animal’s saliva comes into direct contact with the broken skin or mucous membrane, it needs to be treated according to PEP. After cleaning the wound in the same way for 15 minutes or more, and receiving rabies vaccination . When a person is judged to be a Class II exposed person and immunocompromised, or when a Class II exposure is on the head or face and the animal is not determined to be healthy, the wound should be treated immediately and a passive rabies immunization agent (i.e., anti-rabies serum or rabies immunoglobulin) should be administered. In cases of Grade III exposure, the wound should be treated immediately and a rabies passive immunization agent administered, followed by rabies vaccination. A booster dose of vaccine should be given on days 15 and 75 after the full vaccination If the re-exposure occurs during the immunization process, continue to complete the full vaccination according to the original procedure without increasing the dose; those re-exposed within six months after the full immunization generally do not need to be reimmunized; those re-exposed within six months to one year after the full immunization should receive one dose of vaccine on days 0 and 3; those re-exposed within 1 to 3 years Those who are re-exposed within 1-3 years should receive 1 dose of vaccine on days 0, 3 and 7; those who are more than 3 years old should receive the entire vaccine.
