一种有效、低成本的伤寒疫苗,特别是针对幼儿的伤寒疫苗,将对发展中国家的疾病负担产生重大影响。伤寒沙门氏菌的毒力衣壳多糖(Vi)与重组突变株铜绿假单胞菌外蛋白A(Vi-REPA)偶联,已被证明是高效的。我们调查了婴儿疫苗中包括的载体蛋白的使用,标准化了接合过程,并开发了生产规模常规批次释放所需的关键分析方法。来自BSL1生物体的Vi,弗劳迪柠檬酸杆菌,菌株WR7011,被用来替代来自伤寒沙门氏菌的Vi。结果表明,在商业疫苗中广泛应用的白喉毒素无毒突变体CRM197与Vi结合,产量较高。VI-CRM197在动物实验中证明是免疫原性的,即使没有佐剂也是如此。因此,Vi-CRM197似乎是为发展中国家开发商业上可行的、有效的伤寒疫苗的合适候选者。
An efficacious, low cost vaccine against typhoid fever, especially for young children, would make a major impact on disease burden in developing countries. The virulence capsular polysaccharide of Salmonella Typhi (Vi) coupled to recombinant mutant Pseudomonas aeruginosa exoprotein A (Vi-rEPA) has been shown to be highly efficacious. We investigated the use of carrier proteins included in infant vaccines, standardized the conjugation process and developed key assays required for routine lot release at production scale. Vi from a BSL1 organism, Citrobacter freundii, strain WR7011, was used as an alternative to Vi from S. Typhi. We showed that Vi conjugated to CRM197, a non-toxic mutant of diphtheria toxin, widely used in commercial vaccines, was produced at high yield. Vi-CRM197 proved immunogenic in animal studies, even without adjuvant. Thus, Vi-CRM197 appears to be a suitable candidate for the development of a commercially viable, effective typhoid vaccine for developing countries.
