Kennedy offers legal shield to develop hantavirus treatment

• There's no antiviral treatment or vaccine currently available for the Andes type of hantavirus.

Driving the news: Kennedy extended legal protections through July 18 to develop favipiravir, an experimental antiviral used to manage influenza and other infections, according to a Federal Register filing.

• Britain obtained supplies of the drug from Japan last week as part of its response to the hantavirus outbreak linked to the MV Hondius cruise ship, Reuters reported.
• Kennedy invoked the PREP Act, which limits drugmakers' financial losses connected to the use of treatments in a public health emergency and has been the object of repeal attempts by some Republicans in Congress.

What they're saying: "This action helps remove barriers to research and response efforts while we continue monitoring the recent outbreak linked to the South Atlantic cruise ship," Kennedy wrote on X.

• "[Health and Human Services] is taking this situation seriously and will continue working to protect public health and support the safe development of potential treatments and countermeasures."

• The post drew quick criticism from some Kennedy allies — including his former campaign communications director Del Bigtree — who questioned whether Kennedy was reversing past stands on corporate accountability.

Kennedy has taken aim at vaccine makers' federal liability protections in the past by calling for an overhaul of the Vaccine Injury Compensation Program, which which was established in the 1980s in response to the threat of vaccine lawsuits leading to shortages.
