ATS and tetanus toxoid: what patients should know

They are not interchangeable. A clinician decides whether passive antibodies, vaccination, both, or neither are appropriate by checking the wound and your vaccination history.

ATS commonly stands for antitetanus serum, a preparation containing antibodies that can neutralise tetanus toxin that has not yet attached to nerves. It offers passive protection quickly, but that protection fades. Because traditional ATS may be made from horse serum, it can cause allergic reactions and must be given where staff can recognise and treat them. Human tetanus immunoglobulin may be used instead when available and clinically appropriate.

Tetanus toxoid is an inactivated toxin used in tetanus-containing vaccines. It cannot cause tetanus. It prompts your body to make its own immune response, which takes time and is maintained with the recommended vaccine course and boosters.

Rinse the injury under clean running water, remove visible dirt if it comes away easily, control bleeding with gentle pressure, and cover it with a clean dressing. Do not pour household chemicals into the wound or attempt to close a deep puncture yourself.

Arrange a clinical assessment for a deep or contaminated wound, puncture, animal bite, crush injury, burn, or wound containing soil or dead tissue. Bring any vaccination record you have. The clinician will consider the wound type, when your last tetanus-containing dose was given, whether you completed the initial vaccine course, and whether passive antibodies are indicated.

Seek emergency care for jaw stiffness, painful muscle spasms, difficulty swallowing, breathing trouble, or severe stiffness after a wound. These can occur with tetanus and require hospital treatment; vaccination or ATS should not be used as home treatment once symptoms develop.

After an injection, get emergency help for swelling of the lips or tongue, wheezing, faintness, or widespread hives. Contact a clinician promptly if a wound becomes increasingly red, swollen, painful, drains pus, or is accompanied by fever.

Ask whether the wound needs further cleaning or removal of damaged tissue, whether your vaccine course is complete, which tetanus-containing vaccine is appropriate, and whether passive antibody protection is needed. Also mention previous severe reactions to vaccines, horse-serum products, or immunoglobulin, as well as medicines or conditions that weaken immunity.
