Andes Virus Vaccine Triggers Strong Immune Response in 48-Adult Trial as No Shot Is Approved

4 articles · Updated · abcnews.com · May 11
  • A 2023 early trial in 48 healthy adults found an Andes virus vaccine generated a strong immune response without major safety concerns, offering rare progress against a virus with no approved vaccine.
  • The push is urgent because Andes virus can spread person to person and carries a mortality rate of about 38%, unlike most hantaviruses that mainly pass from rodents to humans.
  • Researchers say broader testing remains difficult because hantavirus cases are rare and geographically sporadic, slowing the path toward FDA approval for U.S. DNA vaccine candidates.
  • Current vaccine work has focused more on Asian hantavirus strains such as Hantaan and Seoul, while no vaccine anywhere is specifically approved for the Andes virus in the Americas.
  • Health experts say the cruise ship outbreak is unlikely to become a global pandemic, and the CDC still considers overall hantavirus risk very low for most people.
With a 38% death rate, why is there still no approved vaccine for the deadly Andes virus?
How did a luxury cruise ship become the perfect incubator for a rare, rodent-borne killer virus?
