Quick Summary

Tetanus is an acute infectious disease caused by toxins produced by the bacterium Clostridium tetani. These toxins attack the nervous system, leading to muscle rigidity and spasms, most notably in the jaw, earning it the nickname "lockjaw." Spores of Clostridium tetani are found in soil and can enter the body through any wound, especially deep ones that create an oxygen-free environment for the bacteria to grow.1

Vaccination with tetanus toxoid is highly effective in preventing the disease. Tetanus toxoid is a modified toxin that stimulates the body to produce antibodies. Widespread use of tetanus toxoid, particularly during World War II, dramatically reduced the incidence of tetanus. Routine immunization schedules, including booster doses, are crucial for maintaining immunity throughout life.2
