A tetanus shot is a tetanus vaccination. If the patient has already completed the tetanus vaccination according to the national immunization program and is still within the vaccine protection period, therefore, another vaccination is not recommended. It may also be that the patient’s wound is a clean wound and does not require tetanus vaccination. In addition, if the patient is allergic and has a positive skin test for tetanus vaccine, tetanus vaccination is also not recommended at this time. The need for tetanus vaccination is based on the premise that the patient has an open trauma with bleeding or damage to the fascia and is more likely to suffer from Clostridium tetani infection. In addition, tetanus vaccination is usually recommended if the patient has a heavily contaminated wound or has been injured by rusty metal, such as nails, iron filings, and other artifacts. After tetanus vaccination, try to quit smoking and drinking, avoid rubbing and getting water at the vaccination site to prevent infection, and if there is discomfort after vaccination, active medical consultation is recommended. Even if the doctor does not recommend tetanus vaccination, the patient needs to treat and care for the wound. The wound can be disinfected with iodophor or medical alcohol, and care should be taken to keep the wound clean and dry. Anti-inflammatory drugs such as penicillin and cephalosporin can be used as prescribed by the doctor if necessary to avoid infection.
