Does a child need a tetanus shot if their hand is cut?
Generally, whether a child needs a tetanus shot after a hand cut depends on the specific condition of the wound and the child's immunization history. If there is any uncertainty, it is recommended to seek medical advice promptly. The details are as follows:

If the wound is superficial and clean, involving only the epidermis, and if the child has completed the full course of tetanus vaccination with a booster dose within the past 5–10 years, a tetanus shot may not be necessary. Such wounds are well-exposed and less likely to harbor bacteria, and an intact immune defense can effectively protect against risk. After rinsing with normal saline and disinfecting with iodine solution, keep the wound dry and monitor daily for signs of redness or swelling; healing usually occurs spontaneously.
However, if the wound is deep, caused by a rusty object, heavily contaminated, or if the child has not been vaccinated according to schedule or has an unclear immunization history, a tetanus shot is required. Deep wounds easily create an anaerobic environment, rusty objects often carry pathogenic bacteria, and lack of immunity significantly increases the risk of infection. The wound must first be thoroughly cleaned (debrided) to remove foreign materials and dead tissue, followed by prompt administration of the vaccine.
During recovery, avoid getting the wound wet, prevent the child from scratching it, and encourage a diet rich in protein. Seek immediate medical attention if signs of pus or fever develop.
