Tetanus is a serious but preventable disease caused by a toxin produced by the Clostridium tetani bacteria, which usually enters the body through cuts, wounds, or deep punctures. The bacteria can be found in soil, dust, or rusted metal. Once inside the body, it affects the nervous system, causing painful muscle stiffness and spasms—often starting in the jaw (commonly called “lockjaw”).

The good news? A Tetanus injection can protect you from this potentially life-threatening condition.
