Ecco Chi Sono Gli Scienziati Oggi : Politici e Azionisti Globalisti.

Il vero virus da quello che si evince dai fatti è il Globalismo.

Gli stessi porci che ieri ci rassicuravano sui giornali ed in televisione che il virus non era uscito da un laboratorio senza che nemmeno loro sapevano se questo era vero o no oggi ci dicono di fare questo o fare quello.

La Scienza oggi è affidata all’ammministrazione di stock di azioni quotate in borsa.

I giornalisti sono sguatteri incompetenti o non risucchierebbero dichiarazioni ufficiali senza verificarne metodi e contenuti e poi spacciarle senza questi controlli per verità assolute alle masse.

Quando Lancet e Nature lanciarono degli articoli di accademici che affermavano, con la potenza della verità assoluta ed a nome e dall’alto della Civiltà Scientifica Umana come collettivo superiore di menti illuminate, che il virus Sars Cov2 non era fuoriuscito da un laboratorio

La pandemia di Covid-19 ha sconvolto la vita in tutto il mondo per più di un anno. Il bilancio delle vittime raggiungerà presto i tre milioni di persone. Tuttavia l’origine della pandemia rimane incerta: le agende politiche dei governi e degli scienziati hanno generato spesse nubi di offuscamento, che la stampa mainstream sembra incapace di dissipare.

In quanto segue selezionerò i fatti scientifici disponibili , che contengono molti indizi su quanto accaduto, e fornirò ai lettori le prove per esprimere i propri giudizi. Cercherò quindi di valutare la complessa questione della colpa, che inizia con, ma si estende ben oltre, il governo cinese.

Alla fine di questo articolo, potresti aver imparato molto sulla biologia molecolare dei virus. Cercherò di mantenere questo processo il più indolore possibile. Ma la scienza non può essere evitata perché per ora, e probabilmente per molto tempo, offre l’unico filo sicuro attraverso il labirinto.

Il virus che ha causato la pandemia è ufficialmente noto come SARS-CoV-2, ma può essere chiamato SARS2 in breve. Come molte persone sanno, ci sono due teorie principali sulla sua origine. Uno è che è passato naturalmente dalla fauna selvatica alle persone. L’altro è che il virus era in fase di studio in un laboratorio, da cui è scappato. È molto importante che sia il caso se speriamo di prevenire un secondo evento del genere.

Descriverò le due teorie, spiegherò perché ognuna è plausibile e poi chiederò quale fornisce la migliore spiegazione dei fatti disponibili. È importante notare che finora non ci sono prove dirette per nessuna delle due teorie. Ciascuno dipende da una serie di congetture ragionevoli, ma finora manca di prove. Quindi ho solo indizi, non conclusioni, da offrire. Ma questi indizi puntano in una direzione specifica. E avendo dedotto quella direzione, delineerò alcuni dei fili in questa matassa intricata del disastro.

Un racconto di due teorie

Dopo che la pandemia è scoppiata per la prima volta nel dicembre 2019, le autorità cinesi hanno riferito che molti casi si erano verificati nel mercato ittico – un luogo che vende animali selvatici per la carne – a Wuhan. Ciò ha ricordato agli esperti l’epidemia di SARS1 del 2002 in cui un virus del pipistrello si era diffuso prima agli zibetti, un animale venduto nei mercati umidi, e dagli zibetti alle persone. Un virus simile ai pipistrelli ha causato una seconda epidemia, nota come MERS, nel 2012. Questa volta l’animale ospite intermedio erano i cammelli.

La decodifica del genoma del virus ha mostrato che apparteneva a una famiglia virale nota come beta-coronavirus, alla quale appartengono anche i virus SARS1 e MERS. La relazione supportava l’idea che, come loro, fosse un virus naturale che era riuscito a saltare dai pipistrelli, tramite un altro ospite animale, alle persone. La connessione al mercato ittico, l’unico altro punto di somiglianza con le epidemie di SARS1 e MERS, è stata presto interrotta: i ricercatori cinesi hanno scoperto casi precedenti a Wuhan senza alcun collegamento con il mercato ittico. Ma questo non sembrava avere importanza quando a breve si sarebbero aspettate così tante ulteriori prove a sostegno dell’emergenza naturale.

Wuhan, tuttavia, è sede del Wuhan Institute of Virology, uno dei principali centri mondiali per la ricerca sui coronavirus. Quindi la possibilità che il virus SARS2 fosse sfuggito dal laboratorio non poteva essere esclusa. Sul tavolo c’erano due ragionevoli scenari di origine.

Fin dall’inizio, le percezioni del pubblico e dei media sono state modellate a favore dello scenario di emergenza naturale da forti dichiarazioni di due gruppi scientifici. Queste affermazioni non furono inizialmente esaminate criticamente come avrebbero dovuto essere.

“Siamo uniti per condannare fermamente le teorie del complotto che suggeriscono che COVID-19 non ha un’origine naturale”, hanno scritto un gruppo di virologi e altri su Lancet il 19 febbraio 2020, quando era davvero troppo presto per essere sicuri cosa era successo. Gli scienziati “concludono in modo schiacciante che questo coronavirus ha avuto origine nella fauna selvatica”, hanno detto, con un appello stimolante ai lettori a stare con i colleghi cinesi in prima linea nella lotta contro la malattia.

Contrariamente all’affermazione degli scrittori della lettera, l’idea che il virus potesse essere sfuggito da un laboratorio ha evocato un incidente, non una cospirazione. Sicuramente doveva essere esplorato, non rifiutato a priori. Un segno distintivo dei bravi scienziati è che si danno molto da fare per distinguere tra ciò che sanno e ciò che non sanno. In base a questo criterio, i firmatari della lettera Lancet si comportavano da poveri scienziati: assicuravano al pubblico fatti che non potevano sapere con certezza fossero veri.

Successivamente si è scoperto che la lettera di Lancet era stata organizzata e redatta da Peter Daszak, presidente della EcoHealth Alliance di New York. L’organizzazione del dottor Daszak ha finanziato la ricerca sul coronavirus presso l’Istituto di virologia di Wuhan. Se il virus SARS2 fosse effettivamente sfuggito alla ricerca da lui finanziata, il dottor Daszak sarebbe potenzialmente colpevole. Questo acuto conflitto di interessi non è stato dichiarato ai lettori di Lancet. Al contrario, la lettera concludeva: “Non dichiariamo interessi in competizione”.

Virologi come il dottor Daszak avevano molto in gioco nell’assegnazione della colpa per la pandemia. Per 20 anni, per lo più sotto l’attenzione del pubblico, stavano giocando a un gioco pericoloso. Nei loro laboratori creavano abitualmente virus più pericolosi di quelli esistenti in natura. Sostenevano che potevano farlo in sicurezza e che, anticipando la natura, potevano prevedere e prevenire gli “spillover” naturali, il passaggio di virus da un ospite animale alle persone. Se SARS2 fosse davvero sfuggito a un simile esperimento di laboratorio, ci si poteva aspettare un selvaggio contraccolpo e la tempesta di indignazione pubblica avrebbe colpito i virologi ovunque, non solo in Cina. “Andrebbe in frantumi l’edificio scientifico da cima a fondo”, ha detto a marzo 2020 un editore del MIT Technology Review, Antonio Regalado .

Una seconda dichiarazione che ha avuto un’enorme influenza nel plasmare gli atteggiamenti pubblici è stata una lettera (in altre parole un pezzo d’opinione, non un articolo scientifico) pubblicata il 17 marzo 2020 sulla rivista Nature Medicine. I suoi autori erano un gruppo di virologi guidati da Kristian G. Andersen dello Scripps Research Institute. “Le nostre analisi mostrano chiaramente che SARS-CoV-2 non è un costrutto di laboratorio o un virus manipolato intenzionalmente”, hanno dichiarato i cinque virologi nel secondo paragrafo della loro lettera.

Purtroppo questo è stato un altro caso di scienza povera, nel senso sopra definito. È vero, alcuni metodi più vecchi per tagliare e incollare i genomi virali conservano segni rivelatori di manipolazione. Ma i metodi più recenti, chiamati approcci “no-see-um” o “senza soluzione di continuità”, non lasciano segni distintivi. Né lo fanno altri metodi per manipolare i virus come il passaggio seriale, il trasferimento ripetuto di virus da una coltura di cellule a un’altra. Se un virus è stato manipolato, sia con un metodo senza interruzioni che tramite passaggio seriale, non c’è modo di sapere che è così. Il dottor Andersen e i suoi colleghi stavano assicurando ai loro lettori qualcosa che non potevano sapere.

La parte di discussione inizia la loro lettera: “È improbabile che SARS-CoV-2 sia emerso attraverso la manipolazione di laboratorio di un coronavirus simile a SARS-CoV”. Ma aspetta, il responsabile non ha detto che il virus chiaramente non era stato manipolato? Il grado di certezza degli autori sembrava scivolare di parecchie tacche quando si trattava di esporre il loro ragionamento.

La ragione dello slittamento è chiara una volta che il linguaggio tecnico è stato penetrato. Le due ragioni addotte dagli autori per supporre che la manipolazione sia improbabile sono decisamente inconcludenti.

In primo luogo, dicono che la proteina spike di SARS2 si lega molto bene al suo bersaglio, il recettore ACE2 umano, ma lo fa in un modo diverso da quello che i calcoli fisici suggeriscono sarebbe la soluzione migliore. Pertanto il virus deve essere derivato dalla selezione naturale, non dalla manipolazione.

Se questo argomento sembra difficile da afferrare, è perché è così teso. L’assunto di base degli autori, non spiegato, è che chiunque cerchi di legare un virus pipistrello a cellule umane potrebbe farlo in un solo modo. Per prima cosa calcolerebbero l’adattamento più forte possibile tra il recettore ACE2 umano e la proteina spike con cui il virus si attacca ad esso. Quindi progetterebbero la proteina spike di conseguenza (selezionando la stringa giusta di unità di amminoacidi che la compongono). Ma poiché la proteina spike SARS2 non è di questo miglior design calcolato, dice il documento Andersen, quindi non può essere stata manipolata.

Ma questo ignora il modo in cui i virologi fanno effettivamente legare le proteine ​​spike ai bersagli scelti, che non è per calcolo ma unendo i geni delle proteine ​​spike da altri virus o per passaggio seriale. Con il passaggio seriale, ogni volta che la progenie del virus viene trasferita a nuove colture cellulari o animali, vengono selezionate le più riuscite fino a quando non ne emerge una che crea un legame molto stretto con le cellule umane. La selezione naturale ha fatto tutto il lavoro pesante. La speculazione del documento Andersen sulla progettazione di una proteina spike virale attraverso il calcolo non ha alcuna incidenza sul fatto che il virus sia stato manipolato o meno da uno degli altri due metodi.

Il resto traducetevelo voi..Io sono già disgustato. Grazie al Globalismo non si potranno prevedere e fermare nuovi pandemie di nuovi virus.

The authors’ second argument against manipulation is even more contrived. Although most living things use DNA as their hereditary material, a number of viruses use RNA, DNA’s close chemical cousin. But RNA is difficult to manipulate, so researchers working on coronaviruses, which are RNA-based, will first convert the RNA genome to DNA. They manipulate the DNA version, whether by adding or altering genes, and then arrange for the manipulated DNA genome to be converted back into infectious RNA.

Only a certain number of these DNA backbones have been described in the scientific literature. Anyone manipulating the SARS2 virus “would probably” have used one of these known backbones, the Andersen group writes, and since SARS2 is not derived from any of them, therefore it was not manipulated. But the argument is conspicuously inconclusive. DNA backbones are quite easy to make, so it’s obviously possible that SARS2 was manipulated using an unpublished DNA backbone.

And that’s it. These are the two arguments made by the Andersen group in support of their declaration that the SARS2 virus was clearly not manipulated. And this conclusion, grounded in nothing but two inconclusive speculations, convinced the world’s press that SARS2 could not have escaped from a lab. A technical critique of the Andersen letter takes it down in harsher words.

Science is supposedly a self-correcting community of experts who constantly check each other’s work. So why didn’t other virologists point out that the Andersen group’s argument was full of absurdly large holes? Perhaps because in today’s universities speech can be very costly. Careers can be destroyed for stepping out of line. Any virologist who challenges the community’s declared view risks having his next grant application turned down by the panel of fellow virologists that advises the government grant distribution agency.

The Daszak and Andersen letters were really political, not scientific statements, yet were amazingly effective. Articles in the mainstream press repeatedly stated that a consensus of experts had ruled lab escape out of the question or extremely unlikely. Their authors relied for the most part on the Daszak and Andersen letters, failing to understand the yawning gaps in their arguments. Mainstream newspapers all have science journalists on their staff, as do the major networks, and these specialist reporters are supposed to be able to question scientists and check their assertions. But the Daszak and Andersen assertions went largely unchallenged.

Doubts about natural emergence

Natural emergence was the media’s preferred theory until around February 2021 and the visit by a World Health Organization commission to China. The commission’s composition and access were heavily controlled by the Chinese authorities. Its members, who included the ubiquitous Dr. Daszak, kept asserting before, during and after their visit that lab escape was extremely unlikely. But this was not quite the propaganda victory the Chinese authorities may have been hoping for. What became clear was that the Chinese had no evidence to offer the commission in support of the natural emergence theory.

This was surprising because both the SARS1 and MERS viruses had left copious traces in the environment. The intermediary host species of SARS1 was identified within four months of the epidemic’s outbreak, and the host of MERS within nine months. Yet some 15 months after the SARS2 pandemic began, and a presumably intensive search, Chinese researchers had failed to find either the original bat population, or the intermediate species to which SARS2 might have jumped, or any serological evidence that any Chinese population, including that of Wuhan, had ever been exposed to the virus prior to December 2019. Natural emergence remained a conjecture which, however plausible to begin with, had gained not a shred of supporting evidence in over a year.

And as long as that remains the case, it’s logical to pay serious attention to the alternative conjecture, that SARS2 escaped from a lab.

Why would anyone want to create a novel virus capable of causing a pandemic? Ever since virologists gained the tools for manipulating a virus’s genes, they have argued they could get ahead of a potential pandemic by exploring how close a given animal virus might be to making the jump to humans. And that justified lab experiments in enhancing the ability of dangerous animal viruses to infect people, virologists asserted.

With this rationale, they have recreated the 1918 flu virus, shown how the almost extinct polio virus can be synthesized from its published DNA sequence, and introduced a smallpox gene into a related virus.

These enhancements of viral capabilities are known blandly as gain-of-function experiments. With coronaviruses, there was particular interest in the spike proteins, which jut out all around the spherical surface of the virus and pretty much determine which species of animal it will target. In 2000 Dutch researchers, for instance, earned the gratitude of rodents everywhere by genetically engineering the spike protein of a mouse coronavirus so that it would attack only cats.

Virologists started studying bat coronaviruses in earnest after these turned out to be the source of both the SARS1 and MERS epidemics. In particular, researchers wanted to understand what changes needed to occur in a bat virus’s spike proteins before it could infect people.

Researchers at the Wuhan Institute of Virology, led by China’s leading expert on bat viruses, Dr. Shi Zheng-li or “Bat Lady”, mounted frequent expeditions to the bat-infested caves of Yunnan in southern China and collected around a hundred different bat coronaviruses.

Dr. Shi then teamed up with Ralph S. Baric, an eminent coronavirus researcher at the University of North Carolina. Their work focused on enhancing the ability of bat viruses to attack humans so as to “examine the emergence potential (that is, the potential to infect humans) of circulating bat CoVs [coronaviruses].” In pursuit of this aim, in November 2015 they created a novel virus by taking the backbone of the SARS1 virus and replacing its spike protein with one from a bat virus (known as SHC014-CoV). This manufactured virus was able to infect the cells of the human airway, at least when tested against a lab culture of such cells.

The SHC014-CoV/SARS1 virus is known as a chimera because its genome contains genetic material from two strains of virus. If the SARS2 virus were to have been cooked up in Dr. Shi’s lab, then its direct prototype would have been the SHC014-CoV/SARS1 chimera, the potential danger of which concerned many observers and prompted intense discussion.

“If the virus escaped, nobody could predict the trajectory,” said Simon Wain-Hobson, a virologist at the Pasteur Institute in Paris.

Dr. Baric and Dr. Shi referred to the obvious risks in their paper but argued they should be weighed against the benefit of foreshadowing future spillovers. Scientific review panels, they wrote, “may deem similar studies building chimeric viruses based on circulating strains too risky to pursue.” Given various restrictions being placed on gain-of function (GOF) research, matters had arrived in their view at “a crossroads of GOF research concerns; the potential to prepare for and mitigate future outbreaks must be weighed against the risk of creating more dangerous pathogens. In developing policies moving forward, it is important to consider the value of the data generated by these studies and whether these types of chimeric virus studies warrant further investigation versus the inherent risks involved.”

That statement was made in 2015. From the hindsight of 2021, one can say that the value of gain-of-function studies in preventing the SARS2 epidemic was zero. The risk was catastrophic, if indeed the SARS2 virus was generated in a gain-of-function experiment.

Inside the Wuhan Institute of Virology

Dr. Baric had developed, and taught Dr. Shi, a general method for engineering bat coronaviruses to attack other species. The specific targets were human cells grown in cultures and humanized mice. These laboratory mice, a cheap and ethical stand-in for human subjects, are genetically engineered to carry the human version of a protein called ACE2 that studs the surface of cells that line the airways.

Dr. Shi returned to her lab at the Wuhan Institute of Virology and resumed the work she had started on genetically engineering coronaviruses to attack human cells.
Dr. Zheng-li Shi in a high safety (level BSL4) lab. Her coronavirus research was done in the much lower safety levels of BSL2 and BSL3 labs.

How can we be so sure?

Because, by a strange twist in the story, her work was funded by the National Institute of Allergy and Infectious Diseases (NIAID), a part of the U.S. National Institutes of Health (NIH). And grant proposals that funded her work, which are a matter of public record, specify exactly what she planned to do with the money.

The grants were assigned to the prime contractor, Dr. Daszak of the EcoHealth Alliance, who subcontracted them to Dr. Shi. Here are extracts from the grants for fiscal years 2018 and 2019. “CoV” stands for coronavirus and “S protein” refers to the virus’s spike protein.

“Test predictions of CoV inter-species transmission. Predictive models of host range (i.e. emergence potential) will be tested experimentally using reverse genetics, pseudovirus and receptor binding assays, and virus infection experiments across a range of cell cultures from different species and humanized mice.”

“We will use S protein sequence data, infectious clone technology, in vitro and in vivo infection experiments and analysis of receptor binding to test the hypothesis that % divergence thresholds in S protein sequences predict spillover potential.”

What this means, in non-technical language, is that Dr. Shi set out to create novel coronaviruses with the highest possible infectivity for human cells. Her plan was to take genes that coded for spike proteins possessing a variety of measured affinities for human cells, ranging from high to low. She would insert these spike genes one by one into the backbone of a number of viral genomes (“reverse genetics” and “infectious clone technology”), creating a series of chimeric viruses. These chimeric viruses would then be tested for their ability to attack human cell cultures (“in vitro”) and humanized mice (“in vivo”). And this information would help predict the likelihood of “spillover,” the jump of a coronavirus from bats to people.

The methodical approach was designed to find the best combination of coronavirus backbone and spike protein for infecting human cells. The approach could have generated SARS2-like viruses, and indeed may have created the SARS2 virus itself with the right combination of virus backbone and spike protein.

It cannot yet be stated that Dr. Shi did or did not generate SARS2 in her lab because her records have been sealed, but it seems she was certainly on the right track to have done so. “It is clear that the Wuhan Institute of Virology was systematically constructing novel chimeric coronaviruses and was assessing their ability to infect human cells and human-ACE2-expressing mice,” says Richard H. Ebright, a molecular biologist at Rutgers University and leading expert on biosafety.

“It is also clear,” Dr. Ebright said, “that, depending on the constant genomic contexts chosen for analysis, this work could have produced SARS-CoV-2 or a proximal progenitor of SARS-CoV-2.” “Genomic context” refers to the particular viral backbone used as the testbed for the spike protein.

The lab escape scenario for the origin of the SARS2 virus, as should by now be evident, is not mere hand-waving in the direction of the Wuhan Institute of Virology. It is a detailed proposal, based on the specific project being funded there by the NIAID.

Even if the grant required the work plan described above, how can we be sure that the plan was in fact carried out? For that we can rely on the word of Dr. Daszak, who has been much protesting for the last 15 months that lab escape was a ludicrous conspiracy theory invented by China-bashers.

On 9 December 2019, before the outbreak of the pandemic became generally known, Dr. Daszak gave an interview in which he talked in glowing terms of how researchers at the Wuhan Institute of Virology had been reprogramming the spike protein and generating chimeric coronaviruses capable of infecting humanized mice.

“And we have now found, you know, after 6 or 7 years of doing this, over 100 new sars-related coronaviruses, very close to SARS,” Dr. Daszak says around minute 28 of the interview. “Some of them get into human cells in the lab, some of them can cause SARS disease in humanized mice models and are untreatable with therapeutic monoclonals and you can’t vaccinate against them with a vaccine. So, these are a clear and present danger….

“Interviewer: You say these are diverse coronaviruses and you can’t vaccinate against them, and no anti-virals — so what do we do?

“Daszak: Well I think…coronaviruses — you can manipulate them in the lab pretty easily. Spike protein drives a lot of what happen with coronavirus, in zoonotic risk. So you can get the sequence, you can build the protein, and we work a lot with Ralph Baric at UNC to do this. Insert into the backbone of another virus and do some work in the lab. So you can get more predictive when you find a sequence. You’ve got this diversity. Now the logical progression for vaccines is, if you are going to develop a vaccine for SARS, people are going to use pandemic SARS, but let’s insert some of these other things and get a better vaccine.” The insertions he referred to perhaps included an element called the furin cleavage site, discussed below, which greatly increases viral infectivity for human cells.

In disjointed style, Dr. Daszak is referring to the fact that once you have generated a novel coronavirus that can attack human cells, you can take the spike protein and make it the basis for a vaccine.

One can only imagine Dr. Daszak’s reaction when he heard of the outbreak of the epidemic in Wuhan a few days later. He would have known better than anyone the Wuhan Institute’s goal of making bat coronaviruses infectious to humans, as well as the weaknesses in the institute’s defense against their own researchers becoming infected.

But instead of providing public health authorities with the plentiful information at his disposal, he immediately launched a public relations campaign to persuade the world that the epidemic couldn’t possibly have been caused by one of the institute’s souped-up viruses. “The idea that this virus escaped from a lab is just pure baloney. It’s simply not true,” he declared in an April 2020 interview.

The Safety Arrangements at the Wuhan Institute of Virology

Dr. Daszak was possibly unaware of, or perhaps he knew all too well, the long history of viruses escaping from even the best run laboratories. The smallpox virus escaped three times from labs in England in the 1960’s and 1970’s, causing 80 cases and 3 deaths. Dangerous viruses have leaked out of labs almost every year since. Coming to more recent times, the SARS1 virus has proved a true escape artist, leaking from laboratories in Singapore, Taiwan, and no less than four times from the Chinese National Institute of Virology in Beijing.

One reason for SARS1 being so hard to handle is that there were no vaccines available to protect laboratory workers. As Dr. Daszak mentioned in his December 19 interview quoted above, the Wuhan researchers too had been unable to develop vaccines against the coronaviruses they had designed to infect human cells. They would have been as defenseless against the SARS2 virus, if it were generated in their lab, as their Beijing colleagues were against SARS1.

A second reason for the severe danger of novel coronaviruses has to do with the required levels of lab safety. There are four degrees of safety, designated BSL1 to BSL4, with BSL4 being the most restrictive and designed for deadly pathogens like the Ebola virus.

The Wuhan Institute of Virology had a new BSL4 lab, but its state of readiness considerably alarmed the State Department inspectors who visited it from the Beijing embassy in 2018. “The new lab has a serious shortage of appropriately trained technicians and investigators needed to safely operate this high-containment laboratory,” the inspectors wrote in a cable of 19 January 2018.

The real problem, however, was not the unsafe state of the Wuhan BSL4 lab but the fact that virologists worldwide don’t like working in BSL4 conditions. You have to wear a space suit, do operations in closed cabinets and accept that everything will take twice as long. So the rules assigning each kind of virus to a given safety level were laxer than some might think was prudent.

Before 2020, the rules followed by virologists in China and elsewhere required that experiments with the SARS1 and MERS viruses be conducted in BSL3 conditions. But all other bat coronaviruses could be studied in BSL2, the next level down. BSL2 requires taking fairly minimal safety precautions, such as wearing lab coats and gloves, not sucking up liquids in a pipette, and putting up biohazard warning signs. Yet a gain-of-function experiment conducted in BSL2 might produce an agent more infectious than either SARS1 or MERS. And if it did, then lab workers would stand a high chance of infection, especially if unvaccinated.

Much of Dr. Shi’s work on gain-of-function in coronaviruses was performed at the BSL2 safety level, as is stated in her publications and other documents. She has said in an interview with Science magazine that “The coronavirus research in our laboratory is conducted in BSL-2 or BSL-3 laboratories.”

“It is clear that some or all of this work was being performed using a biosafety standard — biosafety level 2, the biosafety level of a standard US dentist’s office — that would pose an unacceptably high risk of infection of laboratory staff upon contact with a virus having the transmission properties of SARS-CoV-2,” says Dr. Ebright.

“It also is clear,” he adds, “that this work never should have been funded and never should have been performed.”

This is a view he holds regardless of whether or not the SARS2 virus ever saw the inside of a lab.

Concern about safety conditions at the Wuhan lab was not, it seems, misplaced. According to a fact sheet issued by the State Department on January 21,2021, “ The U.S. government has reason to believe that several researchers inside the WIV became sick in autumn 2019, before the first identified case of the outbreak, with symptoms consistent with both COVID-19 and common seasonal illnesses.”

David Asher, a fellow of the Hudson Institute and former consultant to the State Department, provided more detail about the incident at a seminar. Knowledge of the incident came from a mix of public information and “some high end information collected by our intelligence community,” he said. Three people working at a BSL3 lab at the institute fell sick within a week of each other with severe symptoms that required hospitalization. This was “the first known cluster that we’re aware of, of victims of what we believe to be COVID-19.” Influenza could not completely be ruled out but seemed unlikely in the circumstances, he said.

Comparing the Rival Scenarios of SARS2 Origin

The evidence above adds up to a serious case that the SARS2 virus could have been created in a lab, from which it then escaped. But the case, however substantial, falls short of proof. Proof would consist of evidence from the Wuhan Institute of Virology, or related labs in Wuhan, that SARS2 or a predecessor virus was under development there. For lack of access to such records, another approach is to take certain salient facts about the SARS2 virus and ask how well each is explained by the two rival scenarios of origin, those of natural emergence and lab escape. Here are four tests of the two hypotheses. A couple have some technical detail, but these are among the most persuasive for those who may care to follow the argument.

1) The place of origin.

Start with geography. The two closest known relatives of the SARS2 virus were collected from bats living in caves in Yunnan, a province of southern China. If the SARS2 virus had first infected people living around the Yunnan caves, that would strongly support the idea that the virus had spilled over to people naturally. But this isn’t what happened. The pandemic broke out 1,500 kilometers away, in Wuhan.

Beta-coronaviruses, the family of bat viruses to which SARS2 belongs, infect the horseshoe bat Rhinolophus affinis, which ranges across southern China. The bats’ range is 50 kilometers, so it’s unlikely that any made it to Wuhan. In any case, the first cases of the Covid-19 pandemic probably occurred in September, when temperatures in Hubei province are already cold enough to send bats into hibernation.

What if the bat viruses infected some intermediate host first? You would need a longstanding population of bats in frequent proximity with an intermediate host, which in turn must often cross paths with people. All these exchanges of virus must take place somewhere outside Wuhan, a busy metropolis which so far as is known is not a natural habitat of Rhinolophus bat colonies. The infected person (or animal) carrying this highly transmissible virus must have traveled to Wuhan without infecting anyone else. No one in his or her family got sick. If the person jumped on a train to Wuhan, no fellow passengers fell ill.

It’s a stretch, in other words, to get the pandemic to break out naturally outside Wuhan and then, without leaving any trace, to make its first appearance there.

For the lab escape scenario, a Wuhan origin for the virus is a no-brainer. Wuhan is home to China’s leading center of coronavirus research where, as noted above, researchers were genetically engineering bat coronaviruses to attack human cells. They were doing so under the minimal safety conditions of a BSL2 lab. If a virus with the unexpected infectiousness of SARS2 had been generated there, its escape would be no surprise.

2) Natural history and evolution

The initial location of the pandemic is a small part of a larger problem, that of its natural history. Viruses don’t just make one time jumps from one species to another. The coronavirus spike protein, adapted to attack bat cells, needs repeated jumps to another species, most of which fail, before it gains a lucky mutation. Mutation — a change in one of its RNA units — causes a different amino acid unit to be incorporated into its spike protein and makes the spike protein better able to attack the cells of some other species.

Through several more such mutation-driven adjustments, the virus adapts to its new host, say some animal with which bats are in frequent contact. The whole process then resumes as the virus moves from this intermediate host to people.

In the case of SARS1, researchers have documented the successive changes in its spike protein as the virus evolved step by step into a dangerous pathogen. After it had gotten from bats into civets, there were six further changes in its spike protein before it became a mild pathogen in people. After a further 14 changes, the virus was much better adapted to humans, and with a further 4 the epidemic took off.

But when you look for the fingerprints of a similar transition in SARS2, a strange surprise awaits. The virus has changed hardly at all, at least until recently. From its very first appearance, it was well adapted to human cells. Researchers led by Alina Chan of the Broad Institute compared SARS2 with late stage SARS1, which by then was well adapted to human cells, and found that the two viruses were similarly well adapted. “By the time SARS-CoV-2 was first detected in late 2019, it was already pre-adapted to human transmission to an extent similar to late epidemic SARS-CoV,” they wrote.

Even those who think lab origin unlikely agree that SARS2 genomes are remarkably uniform. Dr. Baric writes that “early strains identified in Wuhan, China, showed limited genetic diversity, which suggests that the virus may have been introduced from a single source.”

A single source would of course be compatible with lab escape, less so with the massive variation and selection which is evolution’s hallmark way of doing business.

The uniform structure of SARS2 genomes gives no hint of any passage through an intermediate animal host, and no such host has been identified in nature.

Proponents of natural emergence suggest that SARS2 incubated in a yet-to-be found human population before gaining its special properties. Or that it jumped to a host animal outside China.

All these conjectures are possible, but strained. Proponents of lab leak have a simpler explanation. SARS2 was adapted to human cells from the start because it was grown in humanized mice or in lab cultures of human cells, just as described in Dr. Daszak’s grant proposal. Its genome shows little diversity because the hallmark of lab cultures is uniformity.

Proponents of laboratory escape joke that of course the SARS2 virus infected an intermediary host species before spreading to people, and that they have identified it — a humanized mouse from the Wuhan Institute of Virology.

3) The furin cleavage site.

The furin cleavage site is a minute part of the virus’s anatomy but one that exerts great influence on its infectivity. It sits in the middle of the SARS2 spike protein. It also lies at the heart of the puzzle of where the virus came from.

The spike protein has two sub-units with different roles. The first, called S1, recognizes the virus’s target, a protein called angiotensin converting enzyme-2 (or ACE2) which studs the surface of cells lining the human airways. The second, S2, helps the virus, once anchored to the cell, to fuse with the cell’s membrane. After the virus’s outer membrane has coalesced with that of the stricken cell, the viral genome is injected into the cell, hijacks its protein-making machinery and forces it to generate new viruses.

But this invasion cannot begin until the S1 and S2 subunits have been cut apart. And there, right at the S1/S2 junction, is the furin cleavage site that ensures the spike protein will be cleaved in exactly the right place.

The virus, a model of economic design, does not carry its own cleaver. It relies on the cell to do the cleaving for it. Human cells have a protein cutting tool on their surface known as furin. Furin will cut any protein chain that carries its signature target cutting site. This is the sequence of amino acid units proline-arginine-arginine-alanine, or PRRA in the code that refers to each amino acid by a letter of the alphabet. PRRA is the amino acid sequence at the core of SARS2’s furin cleavage site.

Viruses have all kinds of clever tricks, so why does the furin cleavage site stand out? Because of all known SARS-related beta-coronaviruses, only SARS2 possesses a furin cleavage site. All the other viruses have their S2 unit cleaved at a different site and by a different mechanism.

How then did SARS2 acquire its furin cleavage site? Either the site evolved naturally, or it was inserted by researchers at the S1/S2 junction in a gain-of-function experiment.

Consider natural origin first. Two ways viruses evolve are by mutation and by recombination. Mutation is the process of random change in DNA (or RNA for coronaviruses) that usually results in one amino acid in a protein chain being switched for another. Many of these changes harm the virus but natural selection retains the few that do something useful. Mutation is the process by which the SARS1 spike protein gradually switched its preferred target cells from those of bats to civets, and then to humans.

Mutation seems a less likely way for SARS2’s furin cleavage site to be generated, even though it can’t completely be ruled out. The site’s four amino acid units are all together, and all at just the right place in the S1/S2 junction. Mutation is a random process triggered by copying errors (when new viral genomes are being generated) or by chemical decay of genomic units. So it typically affects single amino acids at different spots in a protein chain. A string of amino acids like that of the furin cleavage site is much more likely to be acquired all together through a quite different process known as recombination.

Recombination is an inadvertent swapping of genomic material that occurs when two viruses happen to invade the same cell, and their progeny are assembled with bits and pieces of RNA belonging to the other. Beta-coronaviruses will only combine with other beta-coronaviruses but can acquire, by recombination, almost any genetic element present in the collective genomic pool. What they cannot acquire is an element the pool does not possess. And no known SARS-related beta-coronavirus, the class to which SARS2 belongs, possesses a furin cleavage site.

Proponents of natural emergence say SARS2 could have picked up the site from some as yet unknown beta-coronavirus. But bat SARS-related beta-coronaviruses evidently don’t need a furin cleavage site to infect bat cells, so there’s no great likelihood that any in fact possesses one, and indeed none has been found so far.

The proponents’ next argument is that SARS2 acquired its furin cleavage site from people. A predecessor of SARS2 could have been circulating in the human population for months or years until at some point it acquired a furin cleavage site from human cells. It would then have been ready to break out as a pandemic.

If this is what happened, there should be traces in hospital surveillance records of the people infected by the slowly evolving virus. But none has so far come to light. According to the WHO report on the origins of the virus, the sentinel hospitals in Hubei province, home of Wuhan, routinely monitor influenza-like illnesses and “no evidence to suggest substantial SARSCoV-2 transmission in the months preceding the outbreak in December was observed.”

So it’s hard to explain how the SARS2 virus picked up its furin cleavage site naturally, whether by mutation or recombination.

That leaves a gain-of-function experiment. For those who think SARS2 may have escaped from a lab, explaining the furin cleavage site is no problem at all. “Since 1992 the virology community has known that the one sure way to make a virus deadlier is to give it a furin cleavage site at the S1/S2 junction in the laboratory,” writes Dr. Steven Quay, a biotech entrepreneur interested in the origins of SARS2. “At least eleven gain-of-function experiments, adding a furin site to make a virus more infective, are published in the open literature, including [by] Dr. Zhengli Shi, head of coronavirus research at the Wuhan Institute of Virology.”

4) A Question of Codons

There’s another aspect of the furin cleavage site that narrows the path for a natural emergence origin even further.

As everyone knows (or may at least recall from high school), the genetic code uses three units of DNA to specify each amino acid unit of a protein chain. When read in groups of 3, the 4 different kinds of DNA can specify 4 x 4 x 4 or 64 different triplets, or codons as they are called. Since there are only 20 kinds of amino acid, there are more than enough codons to go around, allowing some amino acids to be specified by more than one codon. The amino acid arginine, for instance, can be designated by any of the six codons CGU, CGC, CGA, CGG, AGA or AGG, where A, U, G and C stand for the four different kinds of unit in RNA.

Here’s where it gets interesting. Different organisms have different codon preferences. Human cells like to designate arginine with the codons CGT, CGC or CGG. But CGG is coronavirus’s least popular codon for arginine. Keep that in mind when looking at how the amino acids in the furin cleavage site are encoded in the SARS2 genome.

Now the functional reason why SARS2 has a furin cleavage site, and its cousin viruses don’t, can be seen by lining up (in a computer) the string of nearly 30,000 nucleotides in its genome with those of its cousin coronaviruses, of which the closest so far known is one called RaTG13. Compared with RaTG13, SARS2 has a 12-nucleotide insert right at the S1/S2 junction. The insert is the sequence T-CCT-CGG-CGG-GC. The CCT codes for proline, the two CGG’s for two arginines, and the GC is the beginning of a GCA codon that codes for alanine.

There are several curious features about this insert but the oddest is that of the two side-by-side CGG codons. Only 5% of SARS2’s arginine codons are CGG, and the double codon CGG-CGG has not been found in any other beta-coronavirus. So how did SARS2 acquire a pair of arginine codons that are favored by human cells but not by coronaviruses?

Proponents of natural emergence have an up-hill task to explain all the features of SARS2’s furin cleavage site. They have to postulate a recombination event at a site on the virus’s genome where recombinations are rare, and the insertion of a 12-nucleotide sequence with a double arginine codon unknown in the beta-coronavirus repertoire, at the only site in the genome that would significantly expand the virus’s infectivity.

“Yes, but your wording makes this sound unlikely — viruses are specialists at unusual events,” is the riposte of David L. Robertson, a virologist at the University of Glasgow who regards lab escape as a conspiracy theory. “Recombination is naturally very, very frequent in these viruses, there are recombination breakpoints in the spike protein and these codons appear unusual exactly because we’ve not sampled enough.”

Dr. Robertson is correct that evolution is always producing results that may seem unlikely but in fact are not. Viruses can generate untold numbers of variants but we see only the one-in-a-billion that natural selection picks for survival. But this argument could be pushed too far. For instance any result of a gain-of-function experiment could be explained as one that evolution would have arrived at in time. And the numbers game can be played the other way. For the furin cleavage site to arise naturally in SARS2, a chain of events has to happen, each of which is quite unlikely for the reasons given above. A long chain with several improbable steps is unlikely to ever be completed.

For the lab escape scenario, the double CGG codon is no surprise. The human-preferred codon is routinely used in labs. So anyone who wanted to insert a furin cleavage site into the virus’s genome would synthesize the PRRA-making sequence in the lab and would be likely to use CGG codons to do so.

“When I first saw the furin cleavage site in the viral sequence, with its arginine codons, I said to my wife it was the smoking gun for the origin of the virus,” said David Baltimore, an eminent virologist and former president of CalTech. “These features make a powerful challenge to the idea of a natural origin for SARS2,” he said.

A Third Scenario of Origin

There’s a variation on the natural emergence scenario that’s worth considering. This is the idea that SARS2 jumped directly from bats to humans, without going through an intermediate host as SARS1 and MERS did. A leading advocate is the virologist David Robertson who notes that SARS2 can attack several other species besides humans. He believes the virus evolved a generalist capability while still in bats. Because the bats it infects are widely distributed in southern and central China, the virus had ample opportunity to jump to people, even though it seems to have done so on only one known occasion. Dr. Robertson’s thesis explains why no one has so far found a trace of SARS2 in any intermediate host or in human populations surveilled before December 2019. It would also explain the puzzling fact that SARS2 has not changed since it first appeared in humans — it didn’t need to because it could already attack human cells efficiently.

One problem with this idea, though, is that if SARS2 jumped from bats to people in a single leap and hasn’t changed much since, it should still be good at infecting bats. And it seems it isn’t.

“Tested bat species are poorly infected by SARS-CoV-2 and they are therefore unlikely to be the direct source for human infection,” write a scientific group skeptical of natural emergence.

Still, Dr. Robertson may be onto something. The bat coronaviruses of the Yunnan caves can infect people directly. In April 2012 six miners clearing bat guano from the Mojiang mine contracted severe pneumonia with Covid-19-like symptoms and three eventually died. A virus isolated from the Mojiang mine, called RaTG13, is still the closest known relative of SARS2. Much mystery surrounds the origin, reporting and strangely low affinity of RaTG13 for bat cells, as well as the nature of 8 similar viruses that Dr. Shi reports she collected at the same time but has not yet published despite their great relevance to the ancestry of SARS2. But all that is a story for another time. The point here is that bat viruses can infect people directly, though only in special conditions.

So who else, besides miners excavating bat guano, comes into particularly close contact with bat coronaviruses? Well, coronavirus researchers do. Dr. Shi says she and her group collected more than 1,300 bat samples during some 8 visits to the Mojiang cave between 2012 and 2015, and there were doubtless many expeditions to other Yunnan caves.

Imagine the researchers making frequent trips from Wuhan to Yunnan and back, stirring up bat guano in dark caves and mines, and now you begin to see a possible missing link between the two places. Researchers could have gotten infected during their collecting trips, or while working with the new viruses at the Wuhan Institute of Technology. The virus that escaped from the lab would have been a natural virus, not one cooked up by gain of function.

The direct-from-bats thesis is a chimera between the natural emergence and lab escape scenarios. It’s a possibility that can’t be dismissed. But against it are the facts that 1) both SARS2 and RaTG13 seem to have only feeble affinity for bat cells, so one can’t be fully confident that either ever saw the inside of a bat; and 2) the theory is no better than the natural emergence scenario at explaining how SARS2 gained its furin cleavage site, or why the furin cleavage site is determined by human-preferred arginine codons instead of by the bat-preferred codons.

Where We Are So Far

Neither the natural emergence nor the lab escape hypothesis can yet be ruled out. There is still no direct evidence for either. So no definitive conclusion can be reached.

That said, the available evidence leans more strongly in one direction than the other. Readers will form their own opinion. But it seems to me that proponents of lab escape can explain all the available facts about SARS2 considerably more easily than can those who favor natural emergence.

It’s documented that researchers at the Wuhan Institute of Virology were doing gain-of-function experiments designed to make coronaviruses infect human cells and humanized mice. This is exactly the kind of experiment from which a SARS2-like virus could have emerged. The researchers were not vaccinated against the viruses under study, and they were working in the minimal safety conditions of a BSL2 laboratory. So escape of a virus would not be at all surprising. In all of China, the pandemic broke out on the doorstep of the Wuhan institute. The virus was already well adapted to humans, as expected for a virus grown in humanized mice. It possessed an unusual enhancement, a furin cleavage site, which is not possessed by any other known SARS-related beta-coronavirus, and this site included a double arginine codon also unknown among beta-coronaviruses. What more evidence could you want, aside from the presently unobtainable lab records documenting SARS2’s creation?

Proponents of natural emergence have a rather harder story to tell. The plausibility of their case rests on a single surmise, the expected parallel between the emergence of SARS2 and that of SARS1 and MERS. But none of the evidence expected in support of such a parallel history has yet emerged. No one has found the bat population that was the source of SARS2, if indeed it ever infected bats. No intermediate host has presented itself, despite an intensive search by Chinese authorities that included the testing of 80,000 animals. There is no evidence of the virus making multiple independent jumps from its intermediate host to people, as both the SARS1 and MERS viruses did. There is no evidence from hospital surveillance records of the epidemic gathering strength in the population as the virus evolved. There is no explanation of why a natural epidemic should break out in Wuhan and nowhere else. There is no good explanation of how the virus acquired its furin cleavage site, which no other SARS-related beta-coronavirus possesses, nor why the site is composed of human-preferred codons. The natural emergence theory battles a bristling array of implausibilities.

The records of the Wuhan Institute of Virology certainly hold much relevant information. But Chinese authorities seem unlikely to release them given the substantial chance that they incriminate the regime in the creation of the pandemic. Absent the efforts of some courageous Chinese whistle-blower, we may already have at hand just about all of the relevant information we are likely to get for a while.

So it’s worth trying to assess responsibility for the pandemic, at least in a provisional way, because the paramount goal remains to prevent another one. Even those who aren’t persuaded that lab escape is the more likely origin of the SARS2 virus may see reason for concern about the present state of regulation governing gain-of-function research. There are two obvious levels of responsibility: the first, for allowing virologists to perform gain-of-function experiments, offering minimal gain and vast risk; the second, if indeed SARS2 was generated in a lab, for allowing the virus to escape and unleash a world-wide pandemic. Here are the players who seem most likely to deserve blame.

1. Chinese virologists

First and foremost, Chinese virologists are to blame for performing gain-of-function experiments in mostly BSL2-level safety conditions which were far too lax to contain a virus of unexpected infectiousness like SARS2. If the virus did indeed escape from their lab, they deserve the world’s censure for a foreseeable accident that has already caused the deaths of 3 million people.

True, Dr. Shi was trained by French virologists, worked closely with American virologists and was following international rules for the containment of coronaviruses. But she could and should have made her own assessment of the risks she was running. She and her colleagues bear the responsibility for their actions.

I have been using the Wuhan Institute of Virology as a shorthand for all virological activities in Wuhan. It’s possible that SARS2 was generated in some other Wuhan lab, perhaps in an attempt to make a vaccine that worked against all coronaviruses. But until the role of other Chinese virologists is clarified, Dr. Shi is the public face of Chinese work on coronaviruses, and provisionally she and her colleagues will stand first in line for opprobrium.

2. Chinese authorities

China’s central authorities did not generate SARS2 but they sure did their utmost to conceal the nature of the tragedy and China’s responsibility for it. They suppressed all records at the Wuhan Institute of Virology and closed down its virus databases. They released a trickle of information, much of which may have been outright false or designed to misdirect and mislead. They did their best to manipulate the WHO’s inquiry into the virus’s origins, and led the commission’s members on a fruitless run-around. So far they have proved far more interested in deflecting blame than in taking the steps necessary to prevent a second pandemic.

3. The worldwide community of virologists

Virologists around the world are a loose-knit professional community. They write articles in the same journals. They attend the same conferences. They have common interests in seeking funds from governments and in not being overburdened with safety regulations.

Virologists knew better than anyone the dangers of gain-of-function research. But the power to create new viruses, and the research funding obtainable by doing so, was too tempting. They pushed ahead with gain-of-function experiments. They lobbied against the moratorium imposed on Federal funding for gain-of-function research in 2014 and it was raised in 2017.

The benefits of the research in preventing future epidemics have so far been nil, the risks vast. If research on the SARS1 and MERS viruses could only be done at the BSL3 safety level, it was surely illogical to allow any work with novel coronaviruses at the lesser level of BSL2. Whether or not SARS2 escaped from a lab, virologists around the world have been playing with fire.

Their behavior has long alarmed other biologists. In 2014 scientists calling themselves the Cambridge Working Group urged caution on creating new viruses. In prescient words, they specified the risk of creating a SARS2-like virus. “Accident risks with newly created ‘potential pandemic pathogens’ raise grave new concerns,” they wrote. “Laboratory creation of highly transmissible, novel strains of dangerous viruses, especially but not limited to influenza, poses substantially increased risks. An accidental infection in such a setting could trigger outbreaks that would be difficult or impossible to control.”

When molecular biologists discovered a technique for moving genes from one organism to another, they held a public conference at Asilomar in 1975 to discuss the possible risks. Despite much internal opposition, they drew up a list of stringent safety measures that could be relaxed in future — and duly were — when the possible hazards had been better assessed.

When the CRISPR technique for editing genes was invented, biologists convened a joint report by the U.S., UK and Chinese national academies of science to urge restraint on making heritable changes to the human genome. Biologists who invented gene drives have also been open about the dangers of their work and have sought to involve the public.

You might think the SARS2 pandemic would spur virologists to re-evaluate the benefits of gain-of-function research, even to engage the public in their deliberations. But no. Many virologists deride lab escape as a conspiracy theory and others say nothing. They have barricaded themselves behind a Chinese wall of silence which so far is working well to allay, or at least postpone, journalists’ curiosity and the public’s wrath. Professions that cannot regulate themselves deserve to get regulated by others, and this would seem to be the future that virologists are choosing for themselves.

4. The US Role in Funding the Wuhan Institute of Virology

From June 2014 to May 2019 Dr. Daszak’s EcoHealth Alliance had a grant from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, to do gain-of-function research with coronaviruses at the Wuhan Institute of Virology. Whether or not SARS2 is the product of that research, it seems a questionable policy to farm out high-risk research to unsafe foreign labs using minimal safety precautions. And if the SARS2 virus did indeed escape from the Wuhan institute, then the NIH will find itself in the terrible position of having funded a disastrous experiment that led to death of more than 3 million worldwide, including more than half a million of its own citizens.

The responsibility of the NIAID and NIH is even more acute because for the first three years of the grant to EcoHealth Alliance there was a moratorium on funding gain-of-function research. Why didn’t the two agencies therefore halt the Federal funding as apparently required to do so by law? Because someone wrote a loophole into the moratorium.

The moratorium specifically barred funding any gain-of-function research that increased the pathogenicity of the flu, MERS or SARS viruses. But then a footnote on p.2 of the moratorium document states that “An exception from the research pause may be obtained if the head of the USG funding agency determines that the research is urgently necessary to protect the public health or national security.”

This seems to mean that either the director of the NIAID, Dr. Anthony Fauci, or the director of the NIH, Dr. Francis Collins, or maybe both, would have invoked the footnote in order to keep the money flowing to Dr. Shi’s gain-of-function research.

“Unfortunately, the NIAID Director and the NIH Director exploited this loophole to issue exemptions to projects subject to the Pause –preposterously asserting the exempted research was ‘urgently necessary to protect public health or national security’ — thereby nullifying the Pause,” Dr. Richard Ebright said in an interview with Independent Science News.

When the moratorium was ended in 2017 it didn’t just vanish but was replaced by a reporting system, the Potential Pandemic Pathogens Control and Oversight (P3CO) Framework, which required agencies to report for review any dangerous gain-of-function work they wished to fund.

According to Dr. Ebright, both Dr. Collins and Dr. Fauci “have declined to flag and forward proposals for risk-benefit review, thereby nullifying the P3CO Framework.”

In his view, the two officials, in dealing with the moratorium and the ensuing reporting system, “have systematically thwarted efforts by the White House, the Congress, scientists, and science policy specialists to regulate GoF [gain-of-function] research of concern.”

Possibly the two officials had to take into account matters not evident in the public record, such as issues of national security. Perhaps funding the Wuhan Institute of Virology, which is believed to have ties with Chinese military virologists, provided a window into Chinese biowarfare research. But whatever other considerations may have been involved, the bottom line is that the National Institutes of Health was supporting gain-of-function research, of a kind that could have generated the SARS2 virus, in an unsupervised foreign lab that was doing work in BSL2 biosafety conditions. The prudence of this decision can be questioned, whether or not SARS2 and the death of 3 million people was the result of it.

In Conclusion

If the case that SARS2 originated in a lab is so substantial, why isn’t this more widely known? As may now be obvious, there are many people who have reason not to talk about it. The list is led, of course, by the Chinese authorities. But virologists in the United States and Europe have no great interest in igniting a public debate about the gain-of-function experiments that their community has been pursuing for years.

Nor have other scientists stepped forward to raise the issue. Government research funds are distributed on the advice of committees of scientific experts drawn from universities. Anyone who rocks the boat by raising awkward political issues runs the risk that their grant will not be renewed and their research career will be ended. Maybe good behavior is rewarded with the many perks that slosh around the distribution system. And if you thought that Dr. Andersen and Dr. Daszak might have blotted their reputation for scientific objectivity after their partisan attacks on the lab escape scenario, look at the 2nd and 3rd names on this list of recipients of an $82 million grant announced by the National Institute of Allergy and Infectious Diseases in August 2020.

The US government shares a strange common interest with the Chinese authorities: neither is keen on drawing attention to the fact that Dr. Shi’s coronavirus work was funded by the US National Institutes of Health. One can imagine the behind-the-scenes conversation in which the Chinese government says “If this research was so dangerous, why did you fund it, and on our territory too?” To which the US side might reply, “Looks like it was you who let it escape. But do we really need to have this discussion in public?”

Dr. Fauci is a longtime public servant who served with integrity under President Trump and has resumed leadership in the Biden Administration in handling the Covid epidemic. Congress, no doubt understandably, may have little appetite for hauling him over the coals for the apparent lapse of judgment in funding gain-of-function research in Wuhan.

To these serried walls of silence must be added that of the mainstream media. To my knowledge, no major newspaper or television network has yet provided readers with an in-depth news story of the lab escape scenario, such as the one you have just read, although some have run brief editorials or opinion pieces. One might think that any plausible origin of a virus that has killed three million people would merit a serious investigation. Or that the wisdom of continuing gain-of-function research, regardless of the virus’s origin, would be worth some probing. Or that the funding of gain-of-function research by the NIH and NIAID during a moratorium on such research would bear investigation. What accounts for the media’s apparent lack of curiosity?

The virologists’ omertà is one reason. Science reporters, unlike political reporters, have little innate skepticism of their sources’ motives; most see their role largely as purveying the wisdom of scientists to the unwashed masses. So when their sources won’t help, these journalists are at a loss.

Another reason, perhaps, is the migration of much of the media toward the left of the political spectrum. Because President Trump said the virus had escaped from a Wuhan lab, editors gave the idea little credence. They joined the virologists in regarding lab escape as a dismissible conspiracy theory. During the Trump Administration, they had no trouble in rejecting the position of the intelligence services that lab escape could not be ruled out. But when Avril Haines, President Biden’s director of National Intelligence, said the same thing, she too was largely ignored. This is not to argue that editors should have endorsed the lab escape scenario, merely that they should have explored the possibility fully and fairly.

People round the world who have been pretty much confined to their homes for the last year might like a better answer than their media are giving them. Perhaps one will emerge in time. After all, the more months pass without the natural emergence theory gaining a shred of supporting evidence, the less plausible it may seem. Perhaps the international community of virologists will come to be seen as a false and self-interested guide. The common sense perception that a pandemic breaking out in Wuhan might have something to do with a Wuhan lab cooking up novel viruses of maximal danger in unsafe conditions could eventually displace the ideological insistence that whatever Trump said can’t be true.

And then let the reckoning begin.

The first person to take a serious look at the origins of the SARS2 virus was Yuri Deigin, a biotech entrepreneur in Russia and Canada. In a long and brilliant essay, he dissected the molecular biology of the SARS2 virus and raised, without endorsing, the possibility that it had been manipulated. The essay, published on April 22, 2020, provided a roadmap for anyone seeking to understand the virus’s origins. Deigin packed so much information and analysis into his essay that some have doubted it could be the work of a single individual and suggested some intelligence agency must have authored it. But the essay is written with greater lightness and humor than I suspect are ever found in CIA or KGB reports, and I see no reason to doubt that Dr. Deigin is its very capable sole author.

In Deigin’s wake have followed several other skeptics of the virologists’ orthodoxy. Nikolai Petrovsky calculated how tightly the SARS2 virus binds to the ACE2 receptors of various species and found to his surprise that it seemed optimized for the human receptor, leading him to infer the virus might have been generated in a laboratory. Alina Chan published a paper showing that SARS2 from its first appearance was very well adapted to human cells.

One of the very few establishment scientists to have questioned the virologists’ absolute rejection of lab escape is Richard Ebright, who has long warned against the dangers of gain-of-function research. Another is David A. Relman of Stanford University. “Even though strong opinions abound, none of these scenarios can be confidently ruled in or ruled out with currently available facts,” he wrote. Kudos too to Robert Redfield, former director of the Centers for Disease Control and Prevention, who told CNN on March 26, 2021 that the “most likely” cause of the epidemic was “from a laboratory,” because he doubted that a bat virus could become an extreme human pathogen overnight, without taking time to evolve, as seemed to be the case with SARS2.

Steven Quay, a physician-researcher, has applied statistical and bioinformatic tools to ingenious explorations of the virus’s origin, showing for instance how the hospitals receiving the early patients are clustered along the Wuhan №2 subway line which connects the Institute of Virology at one end with the international airport at the other, the perfect conveyor belt for distributing the virus from lab to globe.

In June 2020 Milton Leitenberg published an early survey of the evidence favoring lab escape from gain-of-function research at the Wuhan Institute of Virology.

Many others have contributed significant pieces of the puzzle. “Truth is the daughter,” said Francis Bacon, “not of authority but time.” The efforts of people such as those named above are what makes it so.
