The whooping cough comes combined with the tetanus booster. It is available free in NSW and letters were sent out to encourage people who were *in regular contact with children / babies* (whatever that means ) to get vaccinated. You just need to ask your GP. Tetanus generally lasts for 10 years unless it is a really dirty wound or you forget and just get given another one Not all tetanus injections include the whooping cough vaccine though!!
