What is the tetanus vaccine for?

Tetanus, sometimes called lockjaw, can cause painful muscle stiffness and spasms. The bacteria may enter through a puncture, cut, burn, bite, crush injury, or wound contaminated with soil or other material. The vaccine prepares the immune system to neutralise the toxin, reducing the chance of serious disease.

Vaccination does not sterilise a wound and does not treat every possible infection. It also does not remove the need for careful cleaning or medical assessment. Protection is built through an appropriate vaccination course and maintained with booster doses when advised.

Keep your vaccination record available and tell a clinician if you are unsure whether you completed the course. After an injury, describe how it happened, when it happened, how deep it is, and whether dirt or a foreign object entered the wound.

Rinse a minor wound with clean running water, remove loose debris without digging into the tissue, and apply a clean dressing. A clinician may recommend vaccination or additional protection according to your history and the wound’s features.

Arrange prompt assessment for a deep, puncture, dirty, crushed, burned, or bite wound, especially when you cannot confirm your vaccination history. Seek urgent help for jaw tightness, difficulty swallowing, breathing problems, widespread stiffness, or repeated muscle spasms.

Ask whether your vaccination course is complete, whether a booster is appropriate, and whether the wound needs professional cleaning or other treatment. Share any previous vaccine reaction, immune-system condition, or pregnancy.
