After age 12, a tetanus booster shot usually is recommended every 10 years. Under special circumstances, however, a doctor may give the booster dose sooner. For example, a tetanus booster is usually given if you get a severe cut or puncture wound and it has been more than 5 years since your last tetanus shot.
The first vaccine can be given as a combination with diphtheria, tetanus and whooping cough. Following doses should be given as diphtheria and tetanus vaccine. A diphtheria and tetanus booster is recommended from 50 years, up to and including 59 years of age, and is provided free of charge in Victoria. See your doctor or ask your local government immunisation service provider for more information.
