Genomic Vaccines Fight Disease in Ways Not Possible Before
Standard vaccines to prevent infectious diseases consist of killed or weakened pathogens or proteins from those microorganisms. Vaccines that treat cancer also rely on proteins. In contrast, a new kind of vaccine, which is poised to make major inroads in medicine, consists of genes. Genomic vaccines promise to offer many advantages, including fast manufacture when a virus, such as Zika or Ebola, suddenly becomes more virulent or widespread. They have been decades in the making, but dozens have now entered clinical trials.
