I think you are slightly mistaken. Due to the danger, DARPA denied the EcoHealth grant application which sought to insert human-specific cleavage sites into CoVs, much like the unique furin cleavage site that SARS-CoV-2 has (see below and link). But according to Congressional committees, NIAID and NIH crafted a grant policy and funded EcoHealth in a way that sidestepped the existing moratorium on gain-of-function research (see letter linked below). I wonder if this is why Anthony Fauci and Francis Collins worked so hard to dispel the obvious possibility of the origin being research-related. It’s a little unclear to what extent EcoHealth violated the terms of the grant and reporting requirements to NIAID and how much that may absolve the research funding.
One poster stated that “the evidence is still overwhelming for covid being a natural virus.” This is incorrect. In fact, there’s almost no evidence at all that SARS-CoV-2 is a natural virus. The main piece of evidence, as presented by China early in the pandemic, was that many of the “initial” cases were clustered in December 2019 around the Huanan Seafood Wholesale Market, with zoonosis implications. However, numerous studies have since found seroprevalence and wastewater detection globally prior to December 2019, meaning SARS-CoV-2 had already spread globally before the “initial” cases at the Seafood Market ever happened (a few links below).
Moreover, any source of zoonosis has never been discovered and despite pursing a zero-COVID strategy, it’s unclear whether China actually continues to look for it.
We will analyze all SARS-CoV gene sequences for appropriately conserved proteolytic cleavage sites in S2 and for the presence of potential furin cleavage sites. SARS- CoV with mismatches in proteolytic cleavage sites can be activated by exogenous trypsin or cathepsin L. Where clear mismatches occur, we will introduce appropriate human specific cleavage sites and evaluate growth potential in Vero cell and HAE cultures. [HAE = human airway epithetlial] In SARS CoV, we will ablate several of these sites based on pseudotyped particle studies and evaluate the impact of select SARS CoVS changes on virus replication and pathogenesis.
Sorry for polluting this thread with detailed COVID stuff, but I think this question is important.
