mRNA Vaccines Now Headed for Shrimp (

  • ViAqua Therapeutics, an Israeli-based biotechnology startup, has secured $8.25 million in funding for its oral RNA-based shrimp vaccine
  • The vaccine targets white spot syndrome virus (WSSV), which leads to a 15% reduction in global shrimp production each year
  • ViAqua plans to administer its RNA-based product via coated feed; the RNA molecules can inhibit gene expression, silencing disease-affected genes
  • Shrimp lack an adaptive immune system, the type that “remembers” exposures to infectious agents, so it’s long been assumed that shrimp cannot be vaccinated; now it’s becoming clear that shrimp do have some defense against viruses, which is only beginning to be understood
