Whether tetanus vaccination is necessary for an abrasion depends on the severity of the injury. For a minor abrasion where the wound is not deep, you can repeatedly rinse the wound with hydrogen peroxide or saline solution to wash off contaminants. After that, disinfect with iodine and perform simple bandaging. Change the dressing as needed. Such abrasions do not require a tetanus shot. However, if the abrasion is severe, the wound is deep, heavily contaminated, or caused by rusty metal, it is essential to receive tetanus vaccination while cleaning the wound in the hospital to prevent tetanus.
