What should you know about tetanus shot?

Tetanus is a serious infection caused by toxin-producing bacteria entering through broken skin. Tetanus-containing vaccines prepare the immune system to respond to that toxin. A shot may be offered as part of routine immunisation, a booster, or protection after an injury. It cannot remove dirt from a wound or treat established tetanus symptoms, so vaccination advice sits alongside proper wound cleaning and medical assessment.

Tell the vaccinator about your previous doses, allergies, pregnancy, immune problems, and any earlier reaction to a vaccine. After an injury, describe how it happened, when it occurred, and whether the object was dirty or the wound was deep. Mild soreness or short-lived tiredness can occur after vaccination. Seek advice if you develop a concerning reaction or have questions about the next dose. You can read more at [Tetanus Vaccination](/treatments/preventive-care-and-vaccination/tetanus-vaccination/).

Arrange prompt care for a deep puncture, crush injury, burn, wound containing soil, or an injury when your vaccination record is unknown. Seek emergency help for breathing difficulty, trouble swallowing, painful muscle stiffness, jaw tightening, or repeated spasms. These are warning signs of possible tetanus and need urgent assessment, regardless of whether a shot has recently been given.

Ask which tetanus-containing vaccine is appropriate, whether you need a booster or a series of doses, and how your wound changes the recommendation. Ask what side effects are expected, what reaction needs urgent help, and how to obtain a written record of vaccination.
