Tetanus immunization — Tetanus is a serious, potentially life-threatening infection that can be transmitted by an animal or human bite. Adults who are bitten should receive a tetanus vaccine (called a tetanus toxoid vaccine) if the last tetanus vaccine was greater than 5 years ago. (See
"Patient information: Adult vaccines".)
In addition, tetanus immune globulin may be recommended if the person is not sure of the date of their last tetanus vaccination. The immune globulin provides additional protection against tetanus infection.
