Childhood vaccine
Tetanus Vaccine
The tetanus vaccine protects against tetanus, a serious infection from bacteria in soil and dirt that enter through wounds. It is given in childhood, with boosters after certain injuries.
What it protects against
It protects against tetanus ("lockjaw"), a dangerous infection that causes painful muscle stiffness and spasms, usually entering the body through a dirty wound.
Who it's for
It is part of the routine childhood vaccines (combined with others), with a booster sometimes needed after a dirty or deep wound depending on your vaccination history.
How it works
The vaccine prompts immunity to the tetanus toxin, so the body can neutralise it. Protection lasts many years but a booster may be given after a high-risk wound.
Safety
Safety and side effects
The tetanus vaccine is safe and well established; side effects are usually mild, such as a sore arm.
