What should you know about your first tetanus vaccine?

Tetanus bacteria can enter broken skin, particularly through punctures or wounds containing soil. Their toxin can affect nerves and lead to jaw stiffness, painful muscle spasms, and swallowing or breathing problems. The vaccine teaches the immune system to recognise the toxin. It cannot substitute for cleaning a wound, and one dose may be part of a longer vaccination course rather than the end of protection.

Clean an injury with running water and remove surface dirt without probing deeply. Contact a healthcare professional if the wound is deep, contaminated, caused by a bite, or followed an object piercing the skin. Describe your previous vaccines if you can, as the recommendation depends on both the wound and your record. Keep the injection appointment and follow-up doses that are advised. See [Tetanus Vaccination](/treatments/preventive-care-and-vaccination/tetanus-vaccination/) for more detail.

Get urgent help for difficulty breathing or swallowing, severe jaw stiffness, repeated muscle spasms, confusion, heavy bleeding, or a wound with rapidly worsening pain and swelling. After vaccination, seek immediate care for breathing difficulty, widespread hives, or swelling of the face or throat. Mild tenderness, tiredness, or a short-lived temperature can occur, but persistent or worsening symptoms deserve clinical advice.

Ask whether this is the right time for vaccination, how many follow-up doses may be needed, how to manage arm soreness, and how to protect the wound while it heals.
