For more than a decade, the US government has been funding international programmes engaged in identifying exotic wildlife viruses that might someday infect humans.
But The BMJ revealed on Sept 7 (2023) that a flagship project for hunting viruses among wildlife in South-East Asia, Africa and Latin America to prevent human outbreaks and pandemics is being quietly dropped by the United States Agency for International Development (USAID) after private and bipartisan criticism over the safety of such research.
The shuttering of the project marks an abrupt retreat by the US government from wildlife virus-hunting – an activity that has also been funded by the US Department of Defense and the US National Institutes of Health, reports investigative journalist David Willman.
Risk of a pandemic
The turnabout follows warnings raised by sceptics, including officials within the Biden White House, that the US$125mil (RM584.5mil) DEEP VZN programme could inadvertently ignite a pandemic.
The misgivings continue to resonate now, as the cause of the Covid-19 pandemic – the world’s most deadly such event in a century – remains unproven.
USAID – an arm of the US State Department – launched DEEP VZN (short for Discovery & Exploration of Emerging Pathogens – Viral Zoonoses) in October 2021, succeeding an earlier, decade-long USAID programme called PREDICT, explains Willman.
The agency promoted it as “a critical next step to understand and address the risks posed by zoonotic diseases that can be transmitted from animals to humans”, and said it would help the world “be better prepared to detect, prevent and respond to future biological threats”.
But in July (2023), officials at USAID quietly informed aides to Democratic and Republican members of two US Senate committees with jurisdiction over DEEP VZN that it was being shut down.
This previously-unpublicised decision comes as concerns have heightened over the many risks of working with exotic viruses, including unresolved questions about whether a research mishap or a naturally-occurring spillover of virus from an animal species to humans caused the Covid-19 pandemic.
For instance, in December 2021, two senior White House officials specialising in biosecurity and biosafety – Jason Matheny, deputy assistant to US President Joe Biden for technology and national security, and Daniel Gastfriend, the US National Security Council’s director for biodefence and pandemic preparedness – first privately shared their views with USAID Administrator Samantha Power and advised her to shut down DEEP VZN.
Later, another White House official, Dr T. Gregory McKelvey Jr, a physician and the assistant director for biosecurity with the US Office of Science and Technology Policy, also privately raised concerns with USAID staff.
Power eventually told Matheny and Gastfriend that she would initiate a review of the programme to ensure DEEP VZN could be conducted in a way that adequately managed the risks.
On Sept 6 (2023), USAID said in response to questions from The BMJ, that it had decided to “end the DEEP VZN” project.
The decision, said USAID, reflected “the relative risks and impact of our programming”.
Audit to be done
Matheny, who left the White House in mid-2022 told The BMJ: “It seems likely that the agency assessed that the risks exceeded the benefits of the programme.”
Willman also notes that in May (2023), three leaders of the Republican-controlled US House Energy and Commerce Committee asked the US Government Accountability Office (GAO) to open a scientific audit to “assess the benefits and risks of conducting predictive field research programmes for viruses”.
The US GAO’s acting chief scientist Dr Karen L. Howard estimated in an email to The BMJ that the audit would likely be completed during spring 2024, but declined to discuss any preliminary findings.
Meanwhile, USAID’s funding of the DEEP VZN programme has continued to draw scrutiny behind the scenes from members and staff with both the US Senate Foreign Relations and Senate Appropriations committees, interviews and documents show, writes Willman.
The exchanges between the US Senate and USAID culminated with a brief mention of the previously-unreported termination of DEEP VZN inside the State Department’s fiscal year 2024 appropriation, dated July 20 (2023): “The Committee notes the decision by USAID to cease funding for the exploration of unknown pathogens.”
