Problems solved by technology

In the 1970s, due to serious adverse reactions after inoculation with whole-cell diphtheria pertussis vaccine (DTwP), countries such as Japan and the Netherlands appeared to resist vaccination and stop using it, resulting in a decline in the vaccination rate, resulting in the incidence of pertussis There is a rebound
Although there are similar products (DTaP / Hib / Men) in development both at home and abroad at present, its Hib and Men components still adopt freeze-drying process to prepare corresponding combined vaccines; Reconstitution, the reconstitution process is cumbersome; at the same time, based on the safety risk introduced by the freeze-drying process and the limitation of production capacity, the adsorption of acellular diphtheria-poliovirus inactivated vaccine-Haemophilus influenzae type b (combined)- Research on meningococcal polysaccharide (conjugated) liquid combination vaccine, which has good social and economic value

Abstract

The invention relates to a liquid vacuum composition which comprises diphtheria toxoid, tetanus toxoid, pertussis toxins, filamentous hemagglutinin, pertactin, inactivated poliovirus, type-b haemophilus influenzae capsular polysaccharide-protein conjugate and meningococcus capsular polysaccharide-protein conjugate, wherein the inactivated poliovirus comprises type-I, type-II and type-III poliovirus Sabin strains. By adopting the liquid vacuum composition provided by the invention, security risks caused by freeze-drying processes and limits of production capacities can be avoided, and meanwhile, a tedious redissolution process needed before immunization of a freeze-dried vacuum is avoided. The liquid vacuum composition provided by the invention is capable of preventing six infectious diseases simultaneously, so that the workload of inoculation and the burden of children can be greatly reduced.

Description

technical field [0001] The invention relates to the field of vaccines, in particular to a liquid vaccine composition capable of simultaneously preventing pertussis, diphtheria, tetanus, polio, Haemophilus influenzae type b and Neisseria meningitidis. Background technique [0002] Timely vaccination is an effective preventive and protective measure. Pertussis, diphtheria and tetanus combined vaccine (DTP), as the first vaccine included in the WHO Expanded Immunization Program (EPI), has played an important role in the prevention and control of these three infectious diseases. In the 1970s, due to serious adverse reactions after inoculation with whole-cell diphtheria pertussis vaccine (DTwP), countries such as Japan and the Netherlands appeared to resist vaccination and stop using it, resulting in a decline in the vaccination rate and the incidence of pertussis There is a backlash. At present, in most developed countries, acellular diphtheria pertussis vaccine (DTaP) with le...
