DOCUMENTS RELEASED BY the National Institutes of Health yesterday raise new questions about government-funded research on viruses conducted in China. The annual grant reports from EcoHealth Alliance, which the NIH sent to The Intercept in response to a
lawsuit, provided additional evidence that the U.S. nonprofit — which studies emerging infectious diseases — and its sub-awardee, the Wuhan Institute of Virology, were engaged in risky experiments and that the NIH may not have been fully aware of these activities...
Yesterday, the NIH provided that
missing report for the period ending May 2019, which was inexplicably dated August 2021. That summary of the group’s work includes a description of an experiment the EcoHealth Alliance conducted involving infectious clones of MERS-CoV, the virus that caused a deadly outbreak of Middle East respiratory syndrome in 2012. MERS has a case-fatality rate as high as
35 percent, much higher than Covid-19’s. The scientists swapped out the virus’s receptor-binding domain, or RBD, a part of the spike protein that enables it to enter a host’s cells, according to the report. “We constructed the full-length infectious clone of MERS-CoV, and replaced the RBD of MERS-CoV with the RBDs of various strains of
HKU4-related coronaviruses previously identified in bats from different provinces in southern China,” the scientists wrote.
“Changing the receptor binding site on MERS is sort of crazy,” wrote Jack Nunberg, a virologist and director of the Montana Biotechnology Center at the University of Montana, in an email to The Intercept after reviewing the documents. “Although these new chimeric viruses may retain properties of the MERS-CoV genetic backbone, engineering of a known human pathogen raises new and unpredictable risks beyond those posed by their previously reported studies using a non-pathogenic bat virus backbone.” The researchers’ intent, which some scientists consider integral to defining gain-of-function, remains unclear.

“In the very same report, they showed data that one of their chimeric SARS-like viruses caused more severe disease in a humanized animal model than the original virus,” said Alina Chan, a Boston-based molecular biologist and co-author of the upcoming book “Viral: The Search for the Origin of Covid-19.” “After seeing that result, why did they do similar work using the MERS human pathogen?”
