Abstract

The invention provides adsorbed acellular DTP-Sabin strain polio vaccine and a preparation method thereof. Every 100 ml of polio vaccine contains the following components: 3000-6000ugPN of whooping cough toxin, 3000-6000ugPN of filamentous hemagglutinin,1000-2000ugPN of pertactin, 1000-3000Lf of tetanus toxoid, 3000-6000Lf of diphtheria toxoid, 126-154mg of Al(OH)3, 3000-6000DU of sIPVI type, 5700-7100DU of sIPVII type, 4500-9000DU of sIPVIII type, 765-935mg of NaCl, 0-600mg of -2 phenoxyethanol and the balance of H2O. The vaccine can be used for preventing various target diseases, reducing the vaccination frequency, simplifying the immune procedure, improving the inoculation rate and reducing the risk of cross infection.

Description

technical field [0001] The invention relates to an adsorbed acellular pertussis, diphtheria, tetanus and Sabin strain poliomyelitis combined vaccine and a preparation method thereof, belonging to the technical field of biomedicine. Background technique [0002] Whooping cough is a respiratory infectious disease in children caused by Bordetella pertussis, which is highly contagious. The clinical feature is that the cough gradually worsens, showing paroxysmal spasmodic cough. For untreated patients, the course of the disease can last for 2 to 3 months. Pertussis is one of the main diseases that affect children's health and cause death. Before the implementation of immunization programs, the incidence rate of children under 5 years old reached 20-60%. The vaccines that were first applied were based on whole bacterial cells treated with formaldehyde to kill the bacteria and inactivate the toxic substances. Since the implementation of planned immunization in the late 1970s, the...
