NATIONAL INSTITUTES OF HEALTH (NIH)
The purpose of this notice is to inform the biomedical research community of the following immediate actions NIH is taking in response to the May 5, 2025, Executive Order on Improving the Safety and Security of Biological Research.
Background
NIH continues to emphasize that robust biosafety and biosecurity practices are essential for both promoting and protecting critical, life-saving research. As life sciences research evolves, so must the framework for safeguarding its conduct and results. The May 5, 2025, Executive Order on Improving the Safety and Security of Biological Research takes additional steps to strengthen oversight of research that could or will make a naturally occurring pathogen or toxin more dangerous to American citizens, and directs OSTP and the National Security Advisor to work with federal agencies to revise or replace existing policies overseeing this research. A new policy, to be delivered within 120 days, will replace the proposed DURC/PEPP Policy set to take effect May 6, 2025. Until this new policy is in place, research meeting the definition of dangerous gain-of-function research is to be paused.
For the purposes of this Notice and, as defined in the Executive Order, dangerous gain-of-function research means scientific research on an infectious agent or toxin with the potential to cause disease by enhancing its pathogenicity or increasing its transmissibility. Covered research activities are those that could result in significant societal consequences and that seek or achieve one or more of the following outcomes:
(a) enhancing the harmful consequences of the agent or toxin;
(b) disrupting beneficial immunological response or the effectiveness of an immunization against the agent or toxin;
(c) conferring to the agent or toxin resistance to clinically or agriculturally useful prophylactic or therapeutic interventions against that agent or toxin or facilitating their ability to evade detection methodologies;
(d) increasing the stability, transmissibility, or the ability to disseminate the agent or toxin;
(e) altering the host range or tropism of the agent or toxin;
(f) enhancing the susceptibility of a human host population to the agent or toxin; or
(g) generating or reconstituting an eradicated or extinct agent or toxin.
NIH will continue to provide updates regarding implementation of this Executive Order in alignment with the Administrations guidance, including information on research halts or suspensions. Importantly, an effective and trustworthy oversight system is predicated on an interlocking framework with accountability shared across all partners. NIH encourages all life sciences researchers to assess their research portfolios to ensure we, as a research community, are proactively safeguarding the conduct of biomedical research to fulfill the NIH mission.
