Introduction
In general, "getting protein shots" refers to receiving rabies immune globulin injections. Rabies immune globulin should be administered after being scratched by a dog. Specifically, if the wound is classified as category III exposure—such as single or multiple transdermal bites or scratches, broken skin licked by an animal, or open wounds and mucous membranes contaminated with saliva—rabies immune globulin injection is required.
Generally speaking, "getting a protein shot" refers to the injection of rabies immunoglobulin. Rabies immunoglobulin should be administered after being scratched by a dog. The specific analysis is as follows:
After being scratched by a dog, if the wound is classified as Category III exposure—such as single or multiple transdermal bites or scratches, broken skin licked by an animal, or open wounds and mucous membranes contaminated with saliva—rabies immunoglobulin must be injected. This is because the risk of rabies virus infection is high in cases of Category III exposure. Rabies immunoglobulin provides neutralizing antibodies directly at the wound site, acting immediately on the virus present in the wound, rapidly blocking viral invasion and spread, and offering timely passive immune protection to the body. Even if the dog appears healthy, it cannot be ruled out as a carrier of the rabies virus. Once rabies symptoms develop, the fatality rate is extremely high; therefore, aggressive preventive measures are essential for Category III exposures.
In daily life, it's important to keep the wound clean and dry, get adequate rest, avoid strenuous exercise and alcohol consumption, and minimize contact with unfamiliar dogs—especially stray dogs—to prevent further scratches or bites.
