Some have interpreted this tweet to mean I didn’t think a genetically engineered #OriginOfCovid was possible last year. I did think it was possible & interesting, but not worth pursuing as a top priority.

Now I believe it has to be treated as a top priority for inquiry.
Importantly, even if SARS2 was genetically modified, it doesn’t mean that it was a bioweapon or intended as dual-use.

My reading of the Defuse proposal is that the scientists were genuinely curious and wanted to study rare cleavage sites in SARSrCoVs.

With literally 2020 hindsight, we now know inserting novel cleavage sites into novel SARS-like viruses is a terrible terrible idea. But back in 2018, scientists might not have grasped the risks.
So EcoHealth was given till yesterday to send any unpublished data under just the NIH award to the NIH.

Did they actually send anything to NIH?
And will NIH make all of it public? When should we expect this to happen?
More importantly, can we see the exchanges between EcoHealth and its subcontractors on cleavage site insertion? These may or may not have been funded by specific awards but can tell us a lot about how Covid-19 might have emerged in Wuhan.
Is anyone in leadership asking for these communications?

Where would we be today without all the outsiders, independent analysts and internet sleuths who, month after month, showed that the EcoHealth/Daszak was spreading misinformation about bat coronavirus research in Wuhan? wsj.com/articles/coron…
Were any scientific leaders holding EcoHealth/Daszak accountable?

The community was largely silent even as Daszak was appointed to the @WHO and @TheLancet #OriginOfCovid teams.
Many scientists and science journalists in the public eye continued to cast the lab origin hypothesis as a conspiracy theory and take EcoHealth/Daszak’s word without question for most of 2020+2021.

Step 1 Conduct risky MERS chimera research

Step 2 fail to report results for 2 years

Step 3 when asked by journalists, tell them you didn’t actually do it

Step 4 when journalists discover you did do it, blame the spokesperson science.org/content/articl…
The chimeric SARS-like viruses also did not look enhanced in cells, but when in humanized 🐁 revealed 10,000x higher viral loads & enhanced severity of disease.

EcoHealth showed results that the chimeric MERS virus looked similar to MERS in cells, but what about in humanized 🐁?

Even if you don't think that @WHO or SAGO will be effective at finding the #OriginOfCovid it is in all of our interests that SAGO at least be set up to be balanced, representative of diverse expertise, and free of conflicts of interest.
researchgate.net/publication/35…
@WHO In our letter, we note that there are far too few nominees with backgrounds in biosafety,biosecurity, or forensics (we counted only 2 out of 26) - skills that are critical for realizing SAGO’s mission.
This will fundamentally harm SAGO’s credibility, and the credibility of the WHO by extension. To function optimally, SAGO will require a team able to fairly and credibly examine all pandemic origin hypotheses, both now and in the future.

If SARS2 came from a lab, genetic engineering is very much on the table.

This wasn’t my view 1 year ago. However, in light of grant proposals and reports released in the past 2 months, we know novel SARS-like viruses were being synthesized and engineered at unprecedented scale.
What is going to help inform us on this question “was SARS2 genetically engineered?” is getting full access to all of the communications and documents US-based scientists, editors, and funders had relating to any novel SARSrCoV work.

Not machine learning.
State-of-the-art coronavirus genome engineering has been seamless for several years. You don’t need to be nefarious to make your synthetic genomes seamless.

We can’t use the genome sequence alone to infer whether genetic engineering has occurred.

Looks like @voxdotcom might need to quietly edit its articles again in one year…

Have your #OriginOfCovid reporters been paying any attention to the FOIA’ed and leaked EcoHealth-WIV research proposals and reports in the past 2 months?
Let me help to suggest the edits one year in advance.

“SARS-CoV-2, the virus that causes Covid-19, wasn’t intentionally created in a lab.”

Correct to:

“Scientists cannot determine whether SARS-CoV-2, the virus that causes Covid-19, was created in a lab.”

It makes less and less sense that the WIV didn’t even mention the unique furin cleavage site insertion when they described SARS2 for the first time in their @Nature paper. They had a pipeline for looking for these cleavage sites in rare novel SARSrCoVs. H/t @canardbruno @ydeigin
Before we knew WIV and collaborators had plans to insert novel cleavage sites into novel SARSrCoVs, we were comparing the WIV paper to other first papers on SARS2.

Now that we know WIV was aware and on the lookout for these functional cleavage sites, that comparison is moot.
