Immunizations

Class Summary

These agents immunize patients against tetanus.

Diphtheria-tetanus toxoid (dT)

Diphtheria-tetanus toxoid is used to induce active immunity against tetanus in selected patients. Tetanus and diphtheria toxoids are the immunizing agents of choice for most adults and children older than 7 years. Booster doses are necessary to maintain tetanus immunity throughout life because tetanus spores are ubiquitous.

Pregnant patients should receive only tetanus toxoid, not a diphtheria antigen–containing product. In children and adults, immunization may be administered into the deltoid or midlateral thigh muscles. In infants, the preferred site of administration is the mid thigh laterally.
