A response to World Health Organization
We believe SAGO fails to understand the word “chimera”
On June 27, 2025, the WHO's Scientific Advisory Group for the Origins of Novel Pathogens (SAGO) publicly responded to our private letter:
A report entitled ‘The Most Plausible Origin of SARS-CoV-2’ was also shared with SAGO via email in late May 2025, summarizing a recent book by Haslam, which proposes a laboratory origin of SARS-CoV-2 and incriminating specific individual scientists in the USA, Singapore and China based on the DEFUSE proposal (Haslam and Haslam, 2024). There were several misconceptions, misinterpretations and speculations in this report, some that SAGO addresses here. While recombinant chimeric live vaccine technology has been patented by University of North Carolina (UNC), the DEFUSE proposal did not propose to vaccinate bats using this vaccine. The proposal instead involved recombinant antigen (synthetic protein) vaccine that would not replicate or spread. Implicated proposals by NIH involved vaccinating bats with vectored vaccine (Modified Vaccinia Ankara, Vesicular Stomatitis Virus) which similarly would not spread, and these proposals did not involve coronaviruses. The SHC014 sequence provided by WIV to UNC is not closely related to SARS-CoV-2 but belongs to another sarbecovirus clade (Menachery et al., 2015). Recombinant vaccine vector genome elements including HKU3 do not belong to the clade to which SARS-CoV-2 belongs, so that SARS-CoV-2 cannot be derived from this vector. Animal experiments on SARS-CoV-2 in US laboratories do not allow conclusions regarding geographical origins of SARS-CoV-2. Several additional arguments put forward in the report and book appear to be caused by misunderstandings, misquotations or confusion of terms. These affect all elementary motifs of the overall theory put forward.
The following is a point-by-point rebuttal to SAGO’s valuable feedback:
A report entitled ‘The Most Plausible Origin of SARS-CoV-2’ was also shared with SAGO via email in late May 2025, summarizing a recent book by Haslam, which proposes a laboratory origin of SARS-CoV-2 and incriminating specific individual scientists in the USA, Singapore and China based on the DEFUSE proposal.
We did not “incriminate” scientists in Singapore and China; instead, we provided them with alibis and referred to them as quiet whistleblowers. We identified Ralph Baric, Vincent Munster, and Tony Fauci as the creators and funders of SARS-CoV-2. We highlighted their post-pandemic actions in covering up the origins, as detailed in the timeline below. The world could have managed COVID-19 if we had known SARS-CoV-2 was a contagious animal vaccine.
By definition, a man-made pandemic would have “incriminating” evidence. As the book summarizes, each of them is individually innocent, but collectively they created COVID-19.1 Munster will likely blame Baric’s furin cleavage site, and Baric will probably blame Munster’s aerosol transmission models. Both will likely blame whoever approved the Wuhan bat experiment, which was perhaps Fauci.
While recombinant chimeric live vaccine technology has been patented by UNC, the DEFUSE proposal did not propose to vaccinate bats using this vaccine.
Baric himself stated in the 2018 DARPA Defuse bid that he wanted to test his patented HKU3-Smix chimeric spike antigen as a “targeted broad-based boosting strategy in bats.” Baric’s scope of work was to “lead the targeted immune boosting work…extended to small groups of wild-caught Rhinolophus sinicus bats at WIV.”2
Baric was more explicit in his DARPA Defuse notes, writing, “It is anticipated that recombinant S glycoprotein based vaccines harboring immunogenic blocks across the group 2B coronaviruses will induce broad based immune responses that simultaneously reduce genetically heterogeneous virus burdens in bats, thereby reducing disease risk in these animals for multiple years.”3
The proposal instead involved recombinant antigen (synthetic protein) vaccine that would not replicate or spread.
This is correct, as described in Part 2 of the letter, that Baric’s transferable bat vaccine technology was safe but expensive. Cheaper transmissible technologies were developed at the Rocky Mountain Lab, where Baric and Munster have collaborated since 2013.4
Implicated proposals by NIH involved vaccinating bats with vectored vaccine (Modified Vaccinia Ankara, Vesicular Stomatitis Virus) which similarly would not spread, and these proposals did not involve coronaviruses.
The letter distinguished between Baric’s in vitro work (e.g., 2018 live attenuated bat vaccine referencing the Mojiang mineshaft) and Munster’s in vivo research (e.g., Egyptian fruit bats).5 6 7
We have since reviewed Munster’s DARPA Preempt bid (VSV) for bat “vaccine transmission.” In 2018, Munster claimed he could perform “aerosol vaccination to block transmission from bats to humans.” He also boasted to DARPA about ongoing “bat infection experiments with coronaviruses in Egyptian fruit bats.” Munster’s detailed 2018 bid outlined a test involving naive bats placed with infected bats to test vaccine transmission. Ironically, Tony Schountz of CSU replicated this test in 2020 using Munster’s Egyptian fruit bats and the WA1 isolate from SARS-CoV-2.
The SHC014 sequence provided by WIV to UNC is not closely related to SARS-CoV-2 but belongs to another sarbecovirus clade (Menachery et al., 2015).
Yes, we agree because our letter clearly states that HKU3-Smix and HKU3r-CoV, which were listed in the 2018 and 2019 documentation, are precursors to the SARS-CoV-2 genome.8 Baric described both of these spikes as having a 25% divergence from SARS-CoV-1, and the SARS-CoV-2 spike has a 24.7% divergence. The entire SARS-CoV-2 genome is 20% divergent, matching Baric’s DARPA Defuse notes.9
The SHC014 sample served as a logistical example of Shi’s willingness to share genomes before publication, similar to RaTG13. Baric was reluctant to upload his SHC014-MA15 chimera, indicating his desire to keep his engineering methods secret. Baric was willing to share his SHC014 chimeras with Linfa Wang and Dani Anderson, but not with Shi. For example, Baric wrote to Wang, “Might want to test in captive bats infected with SARS or select SARS-like viruses, like SHC014, which we could provide.”10
Recombinant vaccine vector genome elements including HKU3 do not belong to the clade to which SARS-CoV-2 belongs, so that SARS-CoV-2 cannot be derived from this vector.
Yes, we agree, as nowhere in the letter does it claim that HKU3 is SARS-CoV-2. We believe the committee fails to understand the word “chimera,” which refers to the combination of two or more viruses to create a new genome, like HKU3-Smix. According to Baric’s Figure 1 in his 2018 patent, the HKU3-Smix genome is in the group 2b clade, positioned between HKU3 and SHC014, similar to SARS-CoV-2.11
Baric’s 2018 patent, where HKU3-Smix = SARS-CoV-2
Animal experiments on SARS-CoV-2 in US laboratories do not allow conclusions regarding geographical origins of SARS-CoV-2. Several additional arguments put forward in the report and book appear to be caused by misunderstandings, misquotations or confusion of terms. These affect all elementary motifs of the overall theory put forward.
Due to the unusual logistics of the WA1 isolate, which was collected in Wuhan but isolated in the US, we can also prove a Wuhan area lab leak. Denying this evidence is akin to denying Darwin himself. Once again, the WA1 isolate is the most well-known ancestral strain of SARS-CoV-2, which transmits efficiently among only five known mammals outside of humans.
Suggested corrections to the SAGO report
SAGO’s Table 2 inaccurately includes four species that do not efficiently transmit SARS-CoV-2: raccoon dogs, BALB/c mice, ferrets, and cats.12 While the table correctly lists four of the five known efficient transmission models—deer mice, white-tailed deer, Egyptian fruit bats, and Syrian hamsters—it omits American mink. Notably, none of these five species are native to the Wuhan area.
In other words, the animals thought to have carried SARS-CoV-2 from the Wuhan wet market are actually kept at the Rocky Mountain Lab in Montana. A recent FOIA on Munster’s email indicates he tested unpublished UNC chimeric coronaviruses in Egyptian fruit bats. This unpublished chimera, called “MERS-like” or HKU4, included a furin cleavage site. We also examined Munster’s successful 2018 DARPA PREEMPT grant, which proposed developing a self-disseminating coronavirus vaccine (MERS) in Egyptian fruit bats.
Baric’s 2018 UNC-RML emails indicate he added the furin cleavage site line: “It is possible that the WIV1-CoV S glycoprotein is not processed by surface or intracellular proteases, which have been shown to be important host restriction factors during coronavirus entry.”13 While the SAGO report highlights the MERS-MA30 molecular clone, it does not mention Baric’s reference to that clone in 2019.14
Regarding the discovery of the 2018 DARPA Defuse grant proposal, it was not initially released by Baric or obtained through FOIA. Instead, it was discovered in a Top-Secret Pentagon folder by U.S. Marine Corps Major Joseph Murphy during the summer of 2021.15 A follow-up FOIA was issued by U.S.R.T.K., through the U.S. Geological Survey, to obtain Baric’s detailed notes on his HKU3-Smix chimera.

As for SAGO’s claim that the Defuse proposal was simply “rejected,” unpublished emails from Daszak suggest otherwise. Baric repurposed key language from the Defuse proposal’s Technical Area 1 (TA1) and Technical Area 2 (TA2) sections into two EcoHealth grants submitted by Daszak to NIAID: 2R01AI110964 and U01AI151797.16
For example, in October 2018, Daszak sent Baric the above draft of the NIAID grant. Daszak’s draft used Shi Zhengli’s 2018 progress report, focusing on her WIV1 genome experiments, which are closer to SARS-CoV-1. But Baric added the highlighted 2018 text below with HKU3r-CoVs, or SARS-CoV-2.
In other words, Baric has recycled the TA1 DARPA Defuse text into the NIAID R01 grant renewal. And no one knew, except for Baric. After the DARPA Defuse documents were leaked in September 2021, Daszak appeared caught off guard by Baric’s inclusion of a paragraph proposing the insertion of a furin cleavage site.
Due to NIAID space constraints, the furin cleavage site reference from DARPA Defuse (above) was cut from the final U01AI151797 CREID bid drafted by Baric in June 2019 (below). Baric has recycled text from the TA2 DARPA Defuse text into the NIAID U01 grant.

We raise this not to assign guilt, but to illustrate how Baric’s actions helped obscure the origins of a global tragedy. DRASTIC has since exposed his latest concealment. This draft offers a 2018 window into the mind of a man fixated on testing a live virus with a furin cleavage site in bats at Wuhan.
Most researchers—like Tony Schountz—act in good faith. In fact, Schountz is the only reason we know that Munster aerosolized Baric’s agent.17 In other words, if Schountz didn’t know, then neither did the CIA, SAGO scientists, or the FBI. Yet, when misconduct happens—especially on this level—integrity requires that it be investigated, not ignored.

The Most Plausible Origin of SARS-CoV-2
We address the SAGO Committee to suggest the most plausible origin of SARS-CoV-2 and to recommend investigative priorities and action. Our scenario is based on extensive data of various kinds: forensic, genomic, epidemiological and others, all of which support the scenario we present. There is still considerable evidence to be revealed from records in t…
I am glad you are continuing to pursue the origins of SARS-CoV2 and the subsequent cover-ups with vigor and seemingly endless attention to detail. This is an enormously important question. Every government in the world has failed their citizens entirely by not investigating the origins thoroughly.
I last updated my list of documents and events https://vitamindstopscovid.info/07-origins/ in August 2024/ It starts with a link to this Substack as the best place to keep up with recent developments.
Salute!
