They made these pleas on 27 April, during the first of a series of public listening sessions organized by the US National Institutes of Health (NIH). The sessions are part of a months-long review, conducted by the National Science Advisory Board for Biosecurity (NSABB), of US policies governing risky pathogen research.The board, which advises the US Department of Health and Human Services (HHS), , but the COVID-19 pandemic delayed it. Given that enhanced pathogens could accidentally cause disease outbreaks, the need for the review is now greater than ever, some researchers say.“Pandemics are on people’s minds,” says Marc Lipsitch, an epidemiologist at the Harvard T. H. Chan School of Public Health in Boston, Massachusetts, and an outspoken critic of ‘gain-of-function’ research that modifies pathogens to make them more dangerous to humans. “It’s no longer abstract to think about the destruction that the spread of a new virus can cause.”Although most virologists say that the coronavirus SARS-CoV-2 , some politicians and scientists that the COVID-19 pandemic could have been set off when a modified virus escaped from the Wuhan Institute of Virology (WIV) in China.To address these concerns, in late February, the NIH and the White House Office of Science and Technology Policy asked the NSABB to make swift progress on its long-overdue review. The panel plans to draft a report outlining its recommendations by the end of the year.Manipulating viruses by, say, making them more transmissible in humans can help scientists to answer important questions about how a pathogen evolved or how to defeat it. But US policymakers when the risk of creating a pathogen that is more dangerous outweighs the benefits of the research. The worry is that such a pathogen could be accidentally released or even weaponized.The listening sessions mark the latest chapter in a decade-long effort to better govern such experiments. when two research groups separately reported creating a mutant avian-influenza virus that could be readily transmitted between ferrets breathing the same air. Many worried that such a virus could also spread easily among humans. In 2014, the US government on such experiments after a series of accidents involving mishandled pathogens occurred in government laboratories. in 2017, and the HHS adopted a policy that would add a layer of review to such experiments. The policy created an independent advisory panel to review any research proposals submitted to agencies reporting to the HHS (including the NIH) that describe work on so-called enhanced potential pandemic pathogens (ePPPs). Two years later, that the advisory panel quietly approved two experiments to manipulate avian-influenza viruses similar to those that set off the original uproar, prompting fresh calls for reform.Although the scope of the NSABB’s new review of risky pathogen research remains similar to the one it had planned for 2020, the COVID-19 pandemic will undoubtedly have an influence. The NIH, in particular, during the pandemic for its role in funding potentially risky coronavirus research.In 2014, the WIV received funding from the NIH, through a subcontract with the New-York-based research organization EcoHealth Alliance, to manipulate bat coronaviruses. Some of the funding came during the federal moratorium on gain-of-function research. But the NIH says it approved the funding because the experiments didn’t meet its definition of ePPP research, a stance that has been contested by some US policymakers.In response, Republican lawmakers have introduced draft legislation that would again place a moratorium on the funding of gain-of-function research. This move has alarmed some researchers, including those who attended the 27 April listening session. Felicia Goodrum Sterling, president of the American Society of Virology, based in Ann Arbor, Michigan, pointed out that rapid advances in COVID-19 therapeutics and vaccines were made possible, in part, by manipulating viruses. For example, to create the Johnson &amp; Johnson and Oxford–AstraZeneca COVID-19 vaccines, scientists modified adenoviruses to produce the SARS-CoV-2 spike protein.Many at the listening session pushed for stricter oversight of risky-pathogen research, however. Some suggested that the HHS advisory-panel approach be extended to other US entities. Gregory Koblentz, a biosecurity-policy specialist at George Mason University in Arlington, Virginia, pointed out that pharmaceutical firms, philanthropic institutions and federal agencies, including the Department of Energy, the Department of Agriculture and the Department of Defense, also conduct research on potentially risky pathogens. They should adhere to the same guidelines, he said.In a nod to concerns about the WIV, others thought that the US government should more carefully consider how it funds gain-of-function research abroad and encourage other countries to adopt a similar ePPP review process.Some are also calling for changes to the HHS ePPP review panel itself. Lipsitch would like the identities of the advisers on the panel to be revealed and their comments on research grants to be published (typically, this information is kept confidential). Others worry that if this were to happen, advisers might decline to participate over concerns about harassment. Scientists , particularly those who discuss the origins of SARS-CoV-2.Still, the US government could be more transparent when it comes to biosecurity research, experts said. Tom Inglesby, the director of the Johns Hopkins Center for Health Security in Baltimore, Maryland, called for the risks and benefits of funded experiments to be shared openly, the specific criteria used to evaluate projects to be disclosed and for better guidance in communicating results to the public. This would go a long way to improving public trust in science and the NIH, which has declined during the pandemic, he said.The fact that policies governing ePPPs continue to be tweaked more than a decade after the controversial avian-influenza experiments shows that the issue is extremely nuanced, Koblentz told Nature. He acknowledges the “wonderful benefits” of risky pathogen research, especially with regard to fighting SARS-CoV-2, but he worries that researchers will become complacent about the inherent risk if stricter policies aren’t put in place — especially given that the number of laboratories equipped to handle dangerous pathogens .The NIH plans to host more listening sessions and a public stakeholder meeting before the NSABB finalizes its draft report. A date for these sessions has not yet been set, says Ryan Bayha, a spokesperson for the NIH Office of Science Policy.Nature 605, 203-204 (2022)doi: https://doi.org/10.1038/d41586-022-01209-wVirologyPolicyGovernmentYou have full access to this article via your institution.An essential round-up of science news, opinion and analysis, delivered to your inbox every weekday.Sign up for the Nature Briefing newsletter — what matters in science, free to your inbox daily.
