Definition: The Tetanus & Diphtheria Toxoids Adsorbed for Adult Use is a product that contains a mixture of two bacteria, tetanus toxoid and diphtheria toxoid, which are known to cause tetanus and diphtheria, respectively. The adhesions created by these bacteria on the skin are designed to protect against exposure to them, as well as to prevent the spread of these diseases. The product is intended for adults who have been vaccinated or who may be at risk due to vaccination history, and it has a prescription form in most countries that must be followed according to their local regulations. The adhesions can be removed with soap and water or by applying drops of a disinfectant such as碘伏或ethylenediaminetetraacetic acid (EDTA) on the area. The adhesion strength can vary depending on the amount of adsorbed toxoids, but it should be strong enough to prevent infection. It is important to note that these products are not intended for general use by children under 12 years old or in areas with high risk of exposure to tetanus and diphtheria. It's also worth noting that these adhesions may cause temporary pain or discomfort, but they should be handled carefully as the bacteria can multiply rapidly and produce harmful substances.
