If you weren't immunized as a child, you can start the course of injections at any age. Even if you have had tetanus once, you can get it again and need to be immunized. If you have a cut or weeping wound, such as a burn, you may need a booster dose of tetanus vaccine as a precaution. You may be given a dose of tetanus immunoglobulin which is a protein (antibody) to help your body fight any tetanus infection you might develop. Ask your doctor for more advice.
