This vaccine is given to provide protection (immunity) against tetanus (lockjaw) in adults and children 7 years or older. Vaccination is the best way to protect against this life-threatening disease. Vaccines work by causing the body to produce its own protection (antibodies).
Tetanus vaccine, also known as tetanus toxoid, is an inactive vaccine used to prevent tetanus. During childhood, five doses are recommended, with a sixth given during adolescence. After three doses, almost everyone is initially immune, but additional doses every ten years are recommended to maintain immunity.
