Whether or not to inject vaccines after being bitten by a hamster can only be determined after checking in the hospital. Tetanus vaccine and hemorrhagic fever vaccine may need to be injected, and rabies vaccine is generally not necessary. 1. Tetanus vaccine: If a patient is bitten by a hamster accidentally and then disinfected in the hospital, the wound may cause tetanus infection if it is deeper, so it is necessary for the doctor to determine whether to inject tetanus immunoglobulin and tetanus antitoxin. 2. Hemorrhagic fever vaccine: hamsters may carry hantavirus, which can cause hemorrhagic fever, so patients can be vaccinated against hemorrhagic fever. 3. Rabies vaccine: Rabies vaccine is usually not necessary for hamster bites. This is because the guidelines for rabies control state that rabies prophylaxis is not necessary after being bitten or scratched by rodents. However, it is important to take good care of a hamster bite to avoid infection of the wound. Seek medical attention after being bitten by a hamster, and the need for vaccination will be determined by your doctor based on the condition of the wound.
