Tetanus vacuna: what to know

Tetanus is an infection caused by bacteria that can enter through cuts, punctures, burns, or other breaks in the skin. The bacteria can produce a toxin that affects nerves and muscles, leading to jaw stiffness, painful spasms, and difficulty swallowing or breathing.

The vaccine trains immune protection against the toxin. It is preventive care, not a treatment for symptoms that have already begun. Protection may be reviewed after an injury, particularly when the wound is deep, dirty, or hard to clean.

Rinse a minor wound with clean running water, gently remove surface dirt, and cover it with a clean dressing. Do not probe deeply, seal a contaminated wound at home, or assume a small puncture is harmless.

Arrange medical advice promptly for a puncture, deep cut, crush injury, burn, bite, wound containing dirt or a foreign object, or an injury for which your vaccine history is uncertain. A clinician may clean the wound and decide whether additional protection is needed. See [Tetanus Vaccination](/treatments/preventive-care-and-vaccination/tetanus-vaccination/) for more background.

Get emergency help if you develop jaw tightness, trouble swallowing, painful muscle spasms, widespread stiffness, or breathing difficulty, especially after a wound. Do not wait for symptoms to become severe before seeking assessment.

Ask whether your wound needs professional cleaning, whether your vaccination record is up to date, and which signs would require emergency care. If you have had a reaction to a vaccine, describe what happened and when.
