Why get vaccinated?
Tetanus and diphtheria (Td) vaccine may prevent tetanus and diphtheria that may occur with infection due to C tetani (tetanus) and C diphtheriae (diphtheria).
Infection with C tetani can cause tetanus (painful stiffening of the muscles) and infection with C diphtheriaecan cause diphtheria (difficulty breathing and life-threatening heart failure and paralysis).
Tetanus and diphtheria (Td) vaccine does not contain active bacteria. The vaccine works by triggering the body to make antibodies against the toxins produced by these bacteria to provide a defense against potential infection.
How is the vaccine given?
Tetanus and diphtheria (Td) vaccine comes as a suspension (liquid) to be given intramuscularly (into a muscle) by a healthcare provider.
Tetanus and diphtheria (Td) vaccine is given as directed by your healthcare provider.
What should you tell the person who is giving the vaccine?
Tell your vaccine provider if you:
- have had an allergic reaction to this vaccine, any part of this vaccine, any other vaccine or any drug, food or substance. Tell your vaccine provider about the allergy and what symptoms you had.
- are immunocompromised or are receiving immunosuppressive medications, had an Arthrus reaction (a hard, painful, swollen area at the site of injection) after a tetanus toxoid injection or Guillain-Barré syndrome (a nervous system disorder) within six weeks of a tetanus toxoid injection.

In some cases, your health care provider may decide to postpone vaccination to a future visit.
What are the risks from vaccination?
