Tetanus vaccine, also known as tetanus toxoid (TT), is a toxoid vaccine used to prevent tetanus. [2] During childhood, five doses are recommended, with a sixth given during adolescence. [2] After three doses, almost everyone is initially immune, [2] but additional doses every ten years are recommended to maintain immunity. [3]
In children under the age of seven, the tetanus vaccine is often administered as a combined vaccine, DPT/DTaP vaccine, which also includes vaccines against diphtheria and pertussis. For adults and children over seven, the Td vaccine (tetanus and diphtheria) or Tdap (tetanus, diphtheria, and acellular pertussis) is commonly used. [43]
[6] [1] Tetanospasmin ("tetanus toxin") is a potent toxin with an estimated lethal dose less than 2.5 nanograms per kilogram of body weight, and is responsible for the symptoms of tetanus. [6] [1] Tetanospasmin spreads via the lymphatic system and bloodstream throughout the body, where it is taken up into various parts of the nervous system. [6]
Tetanus is a medical emergency that requires hospitalization, immediate treatment with human tetanus immune globulin (TIG), the tetanus vaccine, drugs to control muscle spasms, aggressive wound care, antibiotics, and depending on how severe the infection is, the patient may need to be put on a ventilator (a machine that breathes for you). [27]
In comparison to alternative vaccine types, such as live attenuated vaccines, the DTP vaccine does not contain any live pathogen, but rather uses inactivated toxoid (and for pertussis, either a dead pathogen or pure antigens) to generate an immune response; therefore, there is not a risk of use in populations that are immune compromised since ...
Immunized adults should have a tetanus booster every 10 years. Anyone helping with post-Helene cleanup should make sure their vaccine is current.
Researchers said their work is the biggest study of its kind on this issue and helps put the risks into context.
Intramuscular injections began to be used for administration of vaccines for diphtheria in 1923, whooping cough in 1926, and tetanus in 1927. [30] By the 1970s, researchers and instructors began forming guidance on injection site and technique to reduce the risk of injection complications and side effects such as pain. [ 8 ]
