HHS Backs 3 Ebola Vaccines with PREP Protections

Health and Human Services today announced a declaration under the Public Readiness and Emergency Preparedness (PREP) Act to facilitate the development and availability of experimental Ebola vaccines.

The declaration provides immunity under United States law against legal claims related to the manufacturing, testing, development, distribution, and administration of three vaccines for Ebola virus disease. It does not, generally, provide immunity for a claim brought in a court outside the United States.

The PREP Act was designed to facilitate the development of medical countermeasures to respond to urgent public health needs, including the development of critical vaccines like those to prevent the spread of Ebola. This U.S. declaration under the PREP act is part of a global dialogue to address these issues in the U.S., and other countries where the vaccine is being developed, manufactured and potentially used.

“My strong hope in issuing this PREP Act declaration in the United States is that other nations will also enact appropriate liability protection and compensation legislation,” said Secretary Sylvia M. Burwell. “As a global community, we must ensure that legitimate concerns about liability do not hold back the possibility of developing an Ebola vaccine, an essential strategy in our global response to the Ebola epidemic in West Africa.”

The PREP Act declaration is expected to strengthen the incentive to conduct research and spur development, manufacturing, and the potential use of the vaccines in large scale vaccination campaigns in West Africa. The PREP Act declaration provides legal protection under U.S. law for three vaccine candidates:

• GlaxoSmithKline’s Recombinant Replication Deficient Chimpanzee Adenovirus Type 3-Vectored Ebola Zaire Vaccine known as ChAd3-EBO-Z
• BPSC1001 vaccine, known as rVSV-ZEBOV-GP, made by BioProtection Services Corporation, a subsidiary of Newlink Genetics
• Ad26.ZEBOV/MVA-BN-Filo vaccine manufactured by Janssen Corporation, subsidiary of Johnson & Johnson/Bavarian Nordic.

Similar PREP Act declarations have been issued, revised or renewed 14 times since the Act was signed in 2005. Past declarations have covered vaccines used in H5N1 pandemic influenza clinical trials in 2008, products related to the H1N1 influenza pandemic in 2009, and the development and manufacturing of antitoxins to treat botulism in 2008.
