- Drug development efforts targeting the rare hantavirus infection have gained renewed attention following a deadly outbreak aboard the Dutch cruise ship MV Hondius last month.

There are currently no approved vaccines or targeted antiviral treatments, and care is largely supportive. Here are some companies and institutions which have hantavirus treatments or vaccines under development:

VACCINES

Ichor Biologics

Antibody-based treatments

Multiple strains

Pre-clinical (last updated its hantavirus program in 2019 and did not immediately respond to a Reuters request for comment on its progress)

UCLA

Antiviral drug favipiravir

Andes and broad strains

Note: "Old World" strains are hantaviruses found in Europe and Asia that cause a kidney disease known as hemorrhagic fever with renal syndrome, while "New World" strains in the Americas cause hantavirus pulmonary syndrome, a severe lung disease
