Definition: The word "Tetanus Toxoid," "Reduced Diphtheria Toxoid," and "Acellular Pertussis Vaccine," adsorbed" describes a vaccine for tetanus toxoid, reduced diphtheria toxoid, and婴幼儿甲型链球菌(adenovirus)腮腺炎疫苗, respectively. - Tetanus Toxoid: This term is used to describe the vaccines that contain a toxin from tetanus. In some cases, it may also be associated with other toxins found in these vaccines, such as diphtheria toxoids or Acellular Pertussis Vaccine. The tetanus toxoid is designed to neutralize the vaccine's active components to prevent tetanus infection. - Reduced Diphtheria Toxoid: This term refers specifically to a reduced dose of tetanus toxoid that has not been exposed to any other toxins in the vaccine. It may be used in conjunction with other vaccines, such as Acellular Pertussis Vaccine or Adenovirus腮腺炎疫苗，to reduce the risk of tetanus infection. - Acellular Pertussis Vaccine: This term refers to a weakened form of pertussis virus that is safe and effective for preventing the infection. It's used with other vaccines, such as Tetanus Toxoid, Reduced Diphtheria Toxoid, or Adenovirus腮腺炎疫苗，together to prevent tetanus. In summary, "Tetanus Toxoid," "Reduced Diphtheria Toxoid," and "Acellular Pertussis Vaccine," adsorbed" are vaccines for tetanus toxoid (tetanus), reduced diphtheria toxoid (diphtheria), and婴幼儿甲型链球菌(adenovirus)腮腺炎疫苗, respectively. These vaccines protect against tetanus infection if the doses of these components in each vaccine are not contaminated with toxins from other strains of pertussis virus."
