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 1897, Edmond Nocard showed that tetanus antitoxin induced passive immunity in humans, and could be used for prophylaxis and treatment. [6] In World War I, injection of tetanus antiserum from horses was widely used as a prophylaxis against tetanus in wounded soldiers, leading to a dramatic decrease in tetanus cases over the course of the war. [9]
In immunology, passive immunity is the transfer of active humoral immunity of ready-made antibodies.Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune ...
On October 2, 1901, a former milk wagon horse named Jim showed signs that he had contracted tetanus and was euthanized. He was used to produce serum containing diphtheria antitoxin (antibodies against diphtheria toxin). Jim produced over 30 US quarts (7.5 US gallons; 28.5 litres) of diphtheria antitoxin in his career.
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]
While GnRH immunity has been known to have contraceptive effects for some time, [4] only in the 2000s has it been used to develop several commercial vaccines. Equity® Oestrus Control is a GnRH vaccine marketed for use in non-breeding domestic horses. Repro-Bloc is GnRH vaccine marketed for use in domestic animals in general. [4]
The 1901 diphtheria antitoxin contamination incident, in which the milk wagon horse used to culture the antitoxin became infected with tetanus, which contaminated vials of the antitoxin leading to the deaths of several children in the midwest United States, [5] led to the passage of the Biologics Control Act of 1902 and the 1906 formation of ...
Anti-tetanus immunoglobulin, also known as tetanus immune globulin (TIG) and tetanus antitoxin, is a medication made up of antibodies against the tetanus toxin. [1] It is used to prevent tetanus in those who have a wound that is at high risk, have not been fully vaccinated with tetanus toxoid , or have HIV/AIDS .
