Rabies vaccine serum refers to anti-rabies serum, which is not mandatory and depends on the specific bite or scratch and other injuries, but rabies vaccine is mandatory after being bitten or scratched by a suspected animal. Rabies vaccine serum, also known as anti-rabies virus immunoglobulin, is an antibody used to neutralize the rabies virus, and is used for emergency prophylaxis and rabies vaccination in more severe cases after a bite or scratch from a suspected rabies virus-infected animal. If the injury reaches the third-degree exposure or serious second-degree exposure such as being scratched or bitten by animals such as cats and dogs and bleeding, scratching and biting on the head and face, skin breaks or mucous membranes being licked, etc., it is necessary to be vaccinated with anti-rabies virus immune globulin under the supervision of a doctor. Ordinary second-degree exposure and below scratching the skin without bleeding or without breaking the skin, may not be inoculated with anti-rabies immune globulin after examination by a doctor, and only receive rabies vaccine. In addition, it is very important to thoroughly flush and treat wounds in a timely manner after an injury to greatly reduce the rate of infection. After being bitten or scratched by a suspected animal, it is important to consult a doctor in a timely manner to treat the wound and receive vaccination, and if necessary, injection of anti-rabies virus serum.
