The genetic diversity of pathogens presents a challenge to the development of broadly effective vaccines. In this issue, Scarselli et al. combine atomic-level structural information with genomics and classical vaccinology to design a single immunogen that elicits protective immunity against more than 300 natural variants of the bacterial pathogen meningococcus B. This accomplishment provides a glimpse of the power of structure-based vaccine design to create immunogens capable of eliciting protective responses against genetically diverse pathogens.
病原体的遗传多样性对广泛有效的疫苗的开发提出了挑战。在本期杂志中,Scarselli 等人将原子水平的结构信息与基因组学和经典疫苗学相结合,设计了一种单一的免疫原,该免疫原能够针对脑膜炎球菌 B 的 300 多种天然变体引发保护性免疫。这一成就让人们看到了基于结构的疫苗设计的威力,这种设计能够创造出能够针对遗传多样性病原体引发保护性反应的免疫原。
