it helps fight diseases and helps prevent, fight and cure infections from a cut or graze or knee.

Tetanus is an immunisation injection against the disease lockjaw (Tetanus). It works by purposefully infecting the recipient with dead cells of the Tetanus virus. This teaches the antibodies in the blood to recognise the virus and attack it. Once the antibodies have seen the virus they make a far more concerted effort to overwhelm and kill it off before it becomes a medical risk to the patient. The Tetanus virus works very quickly and would soon kill an un-immunised person, therefore as a safety precaution a booster is used to refresh the memory of the antibodies from time to time and make them much more aggressive toward the pathogen.
