以无细胞百白破疫苗为基础的联合疫苗的研究进展

Research progress on combined vaccines based on diphtheria-tetanus and acellular pertussis vaccine

联合疫苗(combined vaccine)是将2种或2种以上不同生物体或提纯抗原通过物理方法混合后制成的单一疫苗制剂。联合疫苗的使用能够减少免疫针次,提高儿童的依从性及家长的接受度;降低运输、储存和管理成本;避免漏种,提高疫苗接种率。目前,国外已有多种联合疫苗上市,且具有较好的安全性和免疫原性;国内已有部分联合疫苗上市,还有多种联合疫苗处于临床试验阶段。近年,随着国内组分百日咳疫苗、Sabin株Ⅰ、Ⅱ、Ⅲ型脊髓灰质炎病毒灭活疫苗研发的成功,以无细胞百白破疫苗为基础的联合疫苗得到了较大发展。本文就国内外已上市和临床试验中以无细胞百白破疫苗为基础联合疫苗的研究进展作一综述,以期为国内相关联合疫苗的研发提供思路。

Combined vaccine is a single vaccine preparation made by mixing two or more different organism or purified antigens by physical methods.The use of combined vaccine can reduce the number of immunization shots and improve the compliance of children and acceptance of parents;reduce the costs of transportation,storage and management;avoid missing vaccination and improve vaccination rate.At present,a variety of combined vaccines have been licensed abroad,which have good safety and immunogenicity;some combined vaccines have been put on the market in China,and many combined vaccines are in clinical trials.In recent years,with the successful development of component pertussis vaccine and inactivated poliovirus vaccines of Sabin strainⅠ,ⅡandⅢin China,the combined vaccines based on diphtheria-tetanus-acellular pertussis vaccine(DTaP)have been greatly developed.In this paper,the research progress on combined vaccines based on DTaP,which have been licensed and in clinical trials at home and abroad,was reviewed,in order to provide ideas for the development of related combined vaccines in China.
