Tetanus Prophylaxis for Pediatric Metallic Object Injury

General Recommendations

The Centers for Disease Control and Prevention recommends that for children <7 years old, DTaP should be used for any indicated tetanus prophylaxis, while for children ≥7 years old, Tdap (preferred) or Td should be used if indicated by the specific clinical scenario 1, 2
The American Academy of Pediatrics and the Centers for Disease Control and Prevention suggest that metallic object injuries are classified as contaminated/tetanus-prone wounds because they may be contaminated with dirt, feces, soil, and saliva, and puncture wounds can create anaerobic conditions favorable for Clostridium tetani growth, although this specific fact is from a less preferred source, a more relevant source is not available 3

For children with ≥3 previous doses (completed primary series) and the last dose ≥5 years ago, the Centers for Disease Control and Prevention recommends administering tetanus toxoid-containing vaccine WITHOUT tetanus immune globulin (TIG), using DTaP if the child is <7 years old, and Tdap if the child is ≥7 years old and has not previously received Tdap 1, 2
For children with <3 previous doses or unknown/uncertain history, the Centers for Disease Control and Prevention advises administering BOTH tetanus toxoid-containing vaccine AND TIG (250 units IM), using separate syringes at different anatomical sites, and completing the primary vaccination series with subsequent doses 1, 3

The Centers for Disease Control and Prevention recommends that immunocompromised children, such as those with HIV infection or severe immunodeficiency, should receive TIG regardless of their tetanus immunization history when they have contaminated wounds 1
Children with a history of Arthus reaction following a previous tetanus toxoid-containing vaccine should not receive another dose until >10 years after the most recent dose, regardless of wound severity, as recommended by the Centers for Disease Control and Prevention 1, 2

The Centers for Disease Control and Prevention suggests that for children requiring both vaccine and TIG who have incomplete primary series, completion of the full 3-dose primary vaccination series according to the recommended schedule is essential, as the complete primary tetanus vaccination is nearly 100% effective in preventing tetanus, although the effectiveness fact is from a less preferred source, a more relevant source is not available 1, 4
