What should you know about routine tetanus vaccination?

Tetanus is caused by bacteria that can enter through damaged skin and produce a toxin affecting the nervous system. The vaccine is inactivated, so it cannot cause tetanus; it teaches the immune system to recognise the toxin. Protection is built through the recommended immunisation course and maintained according to local guidance.

A wound does not automatically mean a booster is needed. The decision depends on the wound’s depth and contamination, the person’s vaccination history, and the time since the last dose. A clinician may also discuss additional treatment for a high-risk injury.

For a wound, wash your hands, apply gentle pressure to bleeding, rinse visible dirt away, and arrange medical advice when the injury is deep, contaminated, caused by a bite, or difficult to clean. Take your vaccination record if available. Do not delay assessment while searching for the record; the clinic can help establish the next step.

Seek urgent assessment for a deep puncture, heavily contaminated wound, severe bleeding, loss of sensation, an injury involving the eye or face, or a wound that cannot be cleaned. Emergency symptoms such as jaw stiffness, painful muscle spasms, difficulty swallowing, or breathing problems require immediate help. Wound suturing may be considered only after the injury has been assessed and cleaned.

Ask whether your vaccination record is complete, whether this wound changes the recommendation, whether another treatment is needed, and how to care for the wound while it heals.
