TETANUS; DIPHTHERIA VACCINE reduces the risk of tetanus (lockjaw) and diphtheria. It does not treat tetanus or diphtheria. It is still possible to get tetanus or diphtheria after receiving the vaccine, but the symptoms may be less severe or not last as long. It works by helping your immune system learn how to fight off a future infection.
