Johns Hopkins faculty weigh in on ethics of H5N1 research
In a commentary on the biosecurity controversy surrounding recent publication of bird flu research details, a bioethicist and a vaccine expert at Johns Hopkins reaffirm that “all scientists have an affirmative ethical obligation to avoid contributing to the advancement of biowarfare and bioterrorism” but that there are not sufficient structures in place to evaluate potential societal risks.
The commentary, titled “The Obligation to Prevent the Next Dual-Use Controversy,” appears in the Feb. 9 online Policy Forum of the journal Science. Authors Ruth R. Faden and Ruth A. Karron say that adequate assessment of those risks requires “prospective review by an international body with a range of expertise, including, in this case, influenza virology and biosecurity.”
International prospective review of so-called dual-use research will help mitigate future dilemmas over how to balance global security, academic freedom and public health threats, the authors say. “There is no doubt that there are formidable obstacles to developing such a global oversight body. But that the challenge is hard is no excuse,” Faden and Karron conclude.
Faden is the Philip Franklin Wagley Professor of Biomedical Ethics and director of the Johns Hopkins Berman Institute of Bioethics, and Karron is a professor in the Department of International Health and director of the Center for Immunization Research and the Johns Hopkins Vaccine Initiative at the Johns Hopkins University Bloomberg School of Public Health.
“When you take the perspective that both science and security experts are trying to prevent a global lethal pandemic, the problem becomes one of benefit-risk assessment and risk management,” said Faden, who draws on her experience as a member of the Fink Committee convened by the National Research Council in 2001 to create a roadmap for evaluating biosecurity risks. The Fink Committee’s recommendations led to the creation of the National Science Advisory Board for Biosecurity, which touched off the current controversy over H5N1 (popularly known as “bird flu”) research by calling for the redaction of details explaining how a version of the virus that is readily transmissible in ferrets was produced. The board cited concerns that such details could help terrorists weaponize the flu virus.
“The challenge is to implement effective practices to properly assess and manage these risks that allow for the vigilant stewardship of both the institution of science and public safety,” Faden and Karron write.
The Johns Hopkins co-authors highlight key ethical dimensions of this challenge, including “a moral obligation to ensure that the results of that research are used to help reduce risks to global health,” the prospect of which must be the ethical justification for undertaking the risk of dual-use research at all.
In 2006, the authors worked with other international experts at a meeting in Bellagio, Italy, to address the disproportionate impact that global efforts to prevent a lethal influenza pandemic would have on the world’s disadvantaged. The meeting, organized by the Johns Hopkins Berman Institute of Bioethics, included leaders in the fields of public health, animal health, virology, medicine, public policy, economics, bioethics, law and human rights. In its statement of principles, the group agreed that “developing as well as developed countries should have access to the best available scientific and socioeconomic data and analyses to inform avian and pandemic influenza planning and response.”
