Dr. Anthony Fauci writes in his new "tell-all" that those who argue the COVID-19 pandemic stemmed from a lab leak in Wuhan, China, potentially due to experiments funded by US grants, are promoting a "conspiracy theory" contradicting his own recent testimony before Congress. NIH principal deputy director Dr. Lawrence Tabak told members of the House Select Subcommittee on the Coronavirus Pandemic last month that US taxpayers did fund gain-of-function research on bat SARS viruses at the WIV. Manhattan-based EcoHealth has denied that its work met the controlling definition for that research " or that the experiments could have led to the pandemic. Earlier this week, two scientific experts testified before another Senate committee that evidence points to the experiments at the Wuhan lab as the most likely cause of the COVID-19 pandemic. NIH, which oversees NIAID, awarded more than $500,000 to EcoHealth between 2014 and 2020 that was funneled toward risky viral research at the Wuhan Institute of Virology. The research resulted in a modified virus that was 10,000 times more infectious in lungs, 1 million times more infectious in brains and three times more lethal in humanized lab mice, [Rutgers University molecular biologist Dr. Richard] Ebright testified earlier this week, based on NIH disclosures of the experiment. Another EcoHealth proposal, which was never funded, is seen as a potential way in which the virus could have been created.
