1、Editorial For reprint orders, please contact: Is regulation preventing the development of therapeutics that may prevent future coronavirus pandemics? Timothy P Sheahan*,1 Accepted for publication: 27 November 2017; Published online: 21 February 2018 In the last century, hundreds of new emerging infe
2、ctious diseases (EIDs) have arisen in human populations most of which originate from wild animals as zoonoses1. The recent surge of zoonotic EIDs in human populations is driven by a constellation of socioeconomic factors including human population growth, eroding public health infrastructures, chang
3、es in land use and agriculture and ease of global travel. HIV, Ebola virus, avian infl uenza (H5N1, H7N9, etc.), severe acute respiratory syndrome coronavirus (SARS-CoV) and Middle East respiratory syndrome coronavirus (MERS-CoV) are but a few recent examples of highly virulent, zoonotic viral EIDs

Geopolitical fl ux since the 1990s and the potential for weaponizing EIDs provoked the creation of myriad policies aimed at protecting the USA from bioterrorist threats and the accidental release of potential pandemic pathogen

How are they shaping the direction of individual research programs, the recruitment of new investigators and the stability of impacted fi elds? Below, we discuss our experien

7、atingthetransmission of highly pathogenic avian infl uenza in ferrets set off a fi restorm of debate ultimately resulting in a pause of active GOF research and its future funding3 . While infl uenza research was primarily targeted, GOF policies were also extended to studies that could enhance the pa
8、thogenicity and/or transmissibility of SARS- and MERS-CoV in mammals, requiring regulatory approval of each experiment by NIH or its equivalent. Since the types of mammals were not specifi ed and the assessment of mutant virus in humans or all the other approximately 5400 mammals was obviously not p
9、ossible, the GOF policies by nature of their vagueness could never be adequately satisfi ed. During the pause, a risk and benefi t analysis conducted by the National Science Advisory Board for Biosecurity (NSABB) helped guide the creation of Recommended Policy Guidance for Departmental Development o

Almost a year later, US Department of Health and Human Services (HHS) lifted the pause and released policy intended to guide funding decisions of new grant applications involving potential pand

While the policies for new grant applications are now clear and in place, the triage process of amendments to currently funded grant applications remains unknown, as oftentimes a new recombinant must be made to address an
12、 evolving research question. For CoV researchers, regulatory complexity increased in 2012 when SARS-CoV was designated as a select agent by the HHS and the Centers for Disease Control and Prevention (CDC)7. The Federal Select Agent Program (FSAP) requires those working with pathogens or toxins that
13、pose a severe threat to public health to register and meet certain safety and security standards. Many of the 66 pathogens and toxins accompanying SARS-CoV on the select agent list are infamous including Ebola virus, smallpox and anthrax. As such, the FSAP has many positive FutureVirol.
