The allegation that The River has damaged modern attempts to eradicate polio: more fabrications by doctors Koprowski and Plotkin.

I think it is time to put something important on the record in the public domain, and to do so in forthright fashion.

I have spent some time investigating the claims by doctors Koprowski and Plotkin that The River had damaged modern polio vaccination campaigns – which claims, when I first heard them, caused me some real concern.

I have not found one shred of evidence to support these claims. Furthermore, the supporting references are fabricated. Not one of these references actually does what Koprowski and Plotkin claim – and links The River to people refusing to take polio vaccine in modern times.

This is crucially important, because this aspect of Koprowski and Plotkin’s attack on The River and the OPV/AIDS theory is the only one where their attacks focus on alleged damage done to the general population, rather than alleged damage done to them personally. This, then, represents their attempt to take the higher moral ground. And yet (as I demonstrate below) it is based on falsehoods.

The story begins at the Royal Society conference on “Origins of HIV and the AIDS Epidemic”, in September 2000. At this conference, Hilary Koprowski gave a speech that directly linked “The River” to claims allegedly made by “the Catholic church in Kenya” that modern polio vaccine is contaminated with HIV.

This is what he said: “According to the World Health Organization, it is in India and Africa where vaccination with oral polio vaccine must be completed in order to declare the world polio-free. But then enter THE RIVER with its tale that vaccination against polio may bring the deadly gift of another disease such as AIDS. And what is the response in Africa? The news has spread in Africa, and the Catholic church in Kenya, over the objection of medical authorities, advised mothers not to take their children for polio vaccination as it was contaminated with HIV.” He referenced this allegation to an untitled article in The Nation (a Kenyan daily newspaper) of November 26^th, 1999.

Copies of this speech were released to the Royal Society audience, together with a Koprowski press release which emphasised the same point. In its second paragraph, it read: “[T]oday, instead of celebrating scientific and medical milestone [sic], we have been left with the task of controlling damage done by The River, as a result of which people are questioning the vaccination of children.”

I phoned a Kenyan journalist, who was kind enough to check The Nation of November 26^th, 1999, together with the “Polio” clippings file. She informed me that no such article had been published in The Nation on that day.

This helpful journalist also searched through the “polio” clippings file, and then faxed me copies of articles which reported rumours about the safety of polio vaccines. It became apparent that such rumours had been rife in Kenya for several years. Although some of the rumours revolved around claims of contamination with “AIDS” or “HIV”, most of them related to alleged contamination with “family planning drugs”, presumably intended (in the minds of the rumour-mongers) to render Kenyan males sterile.

She sent me eight reports about alleged polio vaccine contamination, dating from 1996 to 1999. Three of these reports had identified “family planning drugs” and two reports “HIV” as the alleged contaminant, but all of these latter reports had appeared in 1996 and 1997, long before the publication of The River in August, 1999. Since I had never submitted any article about OPV/AIDS theory for publication before August 1999, it was hard to see how my work could be linked to concerns about the safety of modern polio vaccines, as expressed by sections of the Kenyan Catholic church.

I explained these inconsistencies in a response to Koprowski’s articles which was posted on Brian Martin’s web-page on “Polio Vaccines and the Origins of AIDS” a month after the Royal Society meeting, on October 15^th, 2000. I also made sure that whenever I did radio interviews for stations which might broadcast to Africa or elsewhere in the developing world, I assured listeners that “as far as is known, modern polio vaccines are safe”, and emphasised that anyone who was advised that they or their children needed polio vaccination should go ahead and get vaccinated.

Later, I wrote letters with the same message to The Nation, and to the South African magazine, You (which was then serialising The River). In all these interventions, I stressed that I was not questioning the safety of modern polio vaccines, but rather the safety of one particular experimental polio vaccine prepared back in the 1950s.

Koprowski, however, continued to broadcast (both in interviews and in articles) his false allegations that The River was spoiling the campaign to eradicate polio. For instance, in the published version of the Royal Society paper which appeared in July 2001 [H. Koprowski, “Hypotheses and facts”; Phil. Trans. Roy. Soc. (London) B; 2001; 356; 831-833], he again linked The River to the rumours in Kenya, and this time sourced his claim to a specific article in The Nation of November 26^th, 1999, entitled: “Catholic stand on disease criticised”.

In July 2004 I had the opportunity to spend a couple of days in Kenya, and so, with the help of two Kenyan journalists, I checked the back issues of all the Kenyan newspapers for November 26^th, 1999. We confirmed that the article as referenced by Koprowski does not exist – either in The Nation, in the two other newspapers published by National Newspapers: The East African and Taifa Leo, or in Kenya’s other newspaper, The Standard.

Later, at my request, senior reporter Dennis Onyango spent several hours checking through every issue of the Nation from August 23^rd, 1999 (publication date of The River) to December 31^st, 1999. He eventually found an article in The Nation with the title: “Catholic stand on disease criticised”, which was dated November 27^th, 1999. However, this article did not match Koprowski’s description of it in certain crucial respects – which may explain why Koprowski had consistently failed to provide an accurate and complete reference for the article.

This article, published on the day after AIDS had been declared a national disaster by President Moi, focused on criticisms of Catholic clergy by Kenyan members of parliament, who said that they were hindering the fight against HIV and AIDS by preaching against the use of condoms.

The end of the article dealt with a secondary issue: the reports “that some Catholic clergy in Central and some parts of Eastern Province had advised worshippers not [to] take their children for polio vaccination as it was contaminated by HIV.” The article went on: “The allegations were termed as baseless and nonsensical by the Minister of Medical Services, Dr Amukoa Anangwe, who asked why there should be a conspiracy to provide polio kits containing HIV to people of Central and some parts of Eastern provinces.”

At no point in the article was any linkage made between the rumours of vaccine contamination on the one side, and either The River or OPV/AIDS theory on the other.

Indeed, Dennis Onyango, who has been a leading journalist for both The Nation and The Standard since the start of the nineties, assures me that such rumours have nothing to do with my work. He says that he wrote the first Kenyan article about the OPV/AIDS theory in 2000, and assures me that before then, people in Kenya had not even heard of The River.

During my visit to Kenya, I also checked through the “Polio” clippings file at The Nation, which goes back to the 1970s, and reveals that there has been discontent and apathy about polio vaccination since that decade.

A broader survey of the history of vaccination campaigns in Africa reveals that African populations have been sporadically rejecting vaccinations given by Europeans since they were first introduced – in the late nineteenth and early twentieth centuries. Indeed, in several parts of the Belgian Congo (notably parts of Bas-Congo), local people refused to accept the Koprowski vaccines in 1959 and 1960, or else refused to have blood drawn at the time of these vaccinations. The most common rumour then was that such procedures resulted in the “unsexing” of children.

Since Independence in or around 1960, there have been many further instances in different African countries of vaccines being rejected. Newspaper reports reveal that the main causes of popular concern related to fears of contamination with “cancer” and family planning drugs. By the mid-1980s “AIDS” or “HIV” begin to appear as additional alleged vaccine contaminants.

Given this background, it is clear that the rumours that affected some Kenyan communities in the late nineties were part of a continuum of concern about vaccine safety, and were not related either to the OPV/AIDS theory, or to The River.

However, doctors Koprowski and Plotkin have continued to make their sweeping and unsupported accusations in the years since 2000. In 2003, when polio vaccines were rejected in Nigeria, they again claimed that these events were related to my book – and once again, the allegations were unfounded. As has been pointed out in various articles, polio vaccines have only been rejected in the northern, largely Islamic, part of Nigeria, and the rejection relates to ancient religio-political conflicts, exacerbated by the aftermath of 9/11.

This, however, matters little to Stanley Plotkin, who is (among other things) a member of the editorial board of a journal called Vaccine. In a recent editorial he wrote for that journal, he made the sweeping claim that “Hooper’s ideas…have hindered eradication of polio by OPV in Africa”. As evidence, he cited a New York Times article; [Anon: “World briefing/ Africa: Nigeria: 3 States Halt Polio Drive”; New York Times; October 28, 2003, page A6].

In reality, this article states that three northern Nigerian states had refused polio vaccine “because they suspect that the vaccine spreads AIDS and causes cancer and infertility”. However, the article made no mention of any link either to The River, or to OPV/AIDS theory. Once again, therefore, there is no evidence to support the claims by Koprowski and Plotkin that my work, and/or my book, has caused polio cases (and, by implication, deaths from polio) in Africa.

Dr Plotkin’s aggressive position is reflected even more clearly in his e-mails. For instance, after viewing an early version of “The Origin of AIDS” for the first time in December 2003, Plotkin sent a furious e-mail (copied to others) to one of the directors, Peter Chappell. He particularly objected to the ending of the film (which suggested that pharmaceutical companies were concerned not only with safety, but also with profits), and he informed Chappell: “From henceforth, any cases of polio occurring in Africa because of fears that the vaccine is contaminated are on your head, and on Hooper’s. For shame!”

I find it particularly disturbing that, in their determination to try to score points, doctors Koprowski and Plotkin repeatedly claim that recent African refusals to take polio vaccine are linked to my book, and repeatedly allege that there are newspaper articles which support these conclusions.

As I have demonstrated, all these claims are fabrications. The consistent use of such fabrications by Hilary Koprowski and Stanley Plotkin reflects their repeated use of falsehood, fabrication and misrepresentation in other parts of the “origins of AIDS” debate.

What is most astonishing about this is that these gentlemen do not seem to realise that by repeatedly fabricating and falsifying evidence they do huge damage both to their credibility, and to their honour.

POSTSCRIPT.

There was also one apparently independent confirmation that “The River” had damaged the polio vaccination drive in Kenya, and this came from Jon Cohen, who is the resident AIDS reporter for Science magazine. In an article of his (“The Hunt for the Origin of AIDS”) which was published in the October 2000 edition of Atlantic Monthly, Cohen wrote as follows:

Omu Anzala, an AIDS-vaccine researcher at the University of Nairobi, says that ripples from The River have “caused many problems” in Kenya. “When people read The River and they are not very scientific, the arguments are pretty convincing”, he says. Claiming that the vaccine contains HIV, some Kenyan clergymen have recently discouraged their countrymen from taking part in the current campaign to eradicate polio (which uses a thoroughly tested, contaminant-free OPV). “In the last six or seven months we’ve been trying to vaccinate as many people as we can”, Anzala says. “But certain segments of society have been saying, “Who knows whether the vaccine isn’t contaminated?”

This was an interesting paragraph. Although Cohen’s commentary implied that Anzala had linked the book to Kenyan rejection of the vaccine, the quoted passages by Anzala did not in themselves support that conclusion.

In July 2004 I caught up with Professor Anzala at his office in the University of Nairobi, and read him the passage in Jon Cohen’s article. His response was interesting. He repeatedly denied having made these statements, or, indeed, ever having spoken with any journalist about my book. He recalled speaking with Jon Cohen, but said that their discussion had been about AIDS vaccines. He said he had read The River twice and found it a fascinating book, one that had “raised issues that are still being discussed”. When I asked whether he felt that the book had caused any problems for Kenya’s polio eradication drive, Anzala replied: “The problems we have had with polio vaccination have been political problems, and have had nothing to do with The River.”

Background about Jon Cohen and his involvement in the origins-of-AIDS debate.

Jon Cohen has a long history of writing about the OPV/AIDS theory, and down the years his reporting of it has been disturbingly partisan. His first report dealt with Tom Curtis’s article in Rolling Stone, and was condescendingly titled: “Debate on AIDS origin: Rolling Stone weighs in”. He was dismissive of Curtis’s article, and quoted Hilary Koprowski as having told him, Cohen, that “macaques from the Philippines and India” had been used to make the vaccine used in the Congo. Later, in a follow-up letter also published in Science, Cohen claimed that with regard to the source of the kidneys for Koprowski’s vaccine, “I based what I wrote both on what he told me and what he published at the time.”

Many years later, in the months preceding the Royal Society meeting, I heard on the grapevine that Cohen was preparing a long article about the origins debate. Going against the advice of several others, who advised me that Cohen would try to denigrate the hypothesis come what may, I phoned Cohen and invited him to ask me anything he wanted about my work. He said that he had intended to contact me anyway, and so, during the next three or four weeks, we spent several hours on the phone and exchanged several e-mails.

Towards the end of this lengthy exchange, much of which had taken place on my phone time, I asked Cohen if I could put a few questions to him about his responses to the Tom Curtis article, and he agreed. Among these questions, I asked him what his sources were for his statement in Science that he had based what he had written about the kidneys used for making Koprowski’s vaccines “both on what [Koprowski] told me and what he published at the time.”

Cohen responded to my question by e-mail, as follows: “I was referring to page 1153 of ‘Live Poliomyelitis Virus Vaccines’, JAMA, 178(12), December 23, 1961. ‘The material used for growing polioviruses in tissue culture consists of living cells obtained from the freshly harvested kidneys from monkeys brought to the U.S. either from India or the Philippines.'”

The interesting thing about this Koprowski article is that it was published in December 1961, more than a year after Koprowski’s vaccines had been rejected in the US in favour of Sabin’s. Despite this, and the fact that he had by then written thirty-odd articles about polio vaccines, this was the first published statement that Koprowski had ever made about the specific primate species used for growing polioviruses. It was, I felt, something that Koprowski had published after the event, rather than “at the time”.

Furthermore (and more crucially), Koprowski’s statement about using Asian monkeys as a substrate appeared in a section of the article called “The Host Cell”, which uses the passive voice throughout, and which described general techniques then in use in different labs. What was most striking was that in this article, where he had an ideal opportunity to reveal which species he himself had been using, Koprowski failed to do so. He wrote not about the primate species that he himself had used, but instead about the species that are commonly used. (The passive voice, I have since learnt, is one that Koprowski often likes to adopt, especially – it seems – when he wishes to avoid becoming too specific in his statements.)

In his e-mail, Cohen acknowledged that the heading “The Host Cell” was general, that “the passive voice used throughout confuses things”. However, Cohen added that he didn’t agree with me that the context “makes it clear” that Koprowski is referring to techniques generally used, rather than ones he himself had used. He then repeated: “I think the context is confusing”.

Yet by writing this, Cohen admits the flaw in his own argument. In his letter to Science, he had claimed that this particular section of Koprowski’s article had supported Koprowski’s claims that he had used macaque kidneys to make his polio vaccines, and yet he now admitted that Koprowski’s writing in this instance was “confusing”. The Koprowski article had not really been “written at the time” (as Cohen had claimed), and it had not supported Koprowski’s claims of the 1990s that he had only used macaque kidneys as a polio vaccine substrate. Within the context of American journalism which is, at least nominally, religious about its sourcing, Jon Cohen had therefore misled the reader.

Cohen had ended that e-mail to me as follows: “I will admit this: I find re-analyzing Curtis’s article, my response to it, and your responses to my responses tedious and beside the point of exploring your thinking about the origin of the AIDS epidemic.”

That tetchy final statement was revealing, not least because this particular exchange had not been agreed to on the basis of his exploring my responses, but rather of my exploring his. I suspected that the other reason for his tetchiness was that he had been caught out in an error (though he still wasn’t admitting it).

In the end, Cohen’s report of the Royal Society origins meeting in Science was fair and balanced. But his Atlantic Monthly article is a very different kettle of fish. It is a deeply biased article, one that consistently praises the scientists opposing OPV/AIDS, while fairly relentlessly disparaging me.

To take but one example from Cohen’s text: “Hooper has devoted the past decade to researching his book; he portrays himself as an indefatigable investigator who will go to enormous lengths to confront mainstream researchers with their inconsistencies, illogical conclusions, and outright errors. (The River takes me to task as well, for a 1992 Science article in which I critically examined a Rolling Stone story by Tom Curtis about the polio-vaccine theory.) Hooper’s persona in the book is often professorial – “we shall see”, “let us” and “one wonders” – and even condescending, and many researchers who have spoken with him find him obstinate, overzealous, belligerent or worse.”

By the time I had read Cohen’s Atlantic article, I had concluded that here was a man I no longer trusted. I felt he was a very clever man, certainly, but one with a prior agenda, and one who, despite his apparently meticulous attention to detail, occasionally bent the rules (as in the example detailed above). Professor Odzala’s recent denials that he was accurately quoted by Cohen only serve to increase my doubts about him.

In any case, between 2000 and the present, I have heard other revealing stories about Jon Cohen. After our lengthy exchange by phone and e-mail, Cohen and I finally met up at the beginning of the Royal Society meeting, when he strode up to me, full of charm and apparent friendliness. By that stage, of course, his assassination job in the Atlantic was already completed – and down at the printers – so at the very least his approach to me was disingenuous. But in the weeks that followed, I heard from others who had spoken to Cohen, or who had heard him in conversation, at the meeting. Apparently he had been rather outspoken about his opposition to me and to the OPV/AIDS theory. One particular source of indignation, apparently, was his assertion that when I had interviewed Koprowski, Plotkin and others, I had not made it clear to them that I was especially interested in the origin of AIDS, and its possible links to CHAT vaccine.

But once again, Cohen’s stance was partisan. I have made my interest in the AIDS/polio controversy quite clear to most of my interviewees, including doctors Koprowski and Plotkin. However, I was under no obligation to do this. Does Jon Cohen really believe that at the start of every interview I should have said “I am currently 90% persuaded that CHAT vaccine as fed in Africa is linked to the start of the AIDS pandemic”? Does Cohen himself, I wonder, give such a statement of intent at the beginning of all his interviews – including those that deal with controversial topics?

The other interesting story I heard about Cohen came from a professor based in the US, who had had some dealings with Hilary Koprowski in the nineties. The two men had apparently been talking about the Tom Curtis article in Rolling Stone, and Koprowski had been expressing his disgust. “Well at least you seem to have a supporter in Jon Cohen”, said the professor, who had read the exchanges in Science. Koprowski apparently looked at him for some seconds, and then very deliberately mimed putting something into his top pocket. What did that mean?, I asked the professor. “Koprowski was indicating that he had Cohen in his pocket”, he explained.

Be that as it may (and I personally retain some doubts about whether Koprowski’s alleged implication is true), I do believe that Jon Cohen’s interventions in the “origins of AIDS” debate have been fairly consistently biased towards Hilary Koprowski’s position.

There is one major caveat to the last statement, which relates to when Cohen highlighted the shortcomings of phylogenetic dating as a method to predict the birth-date of HIV. I have been writing about the inherent flaws in the phylogenetic dating of HIV-1 for some years now, because the claim that the origins of HIV-1 can be accurately calculated (to the 1930s or 1940s) is a central tenet of committed OPV/AIDS opponents such as Hilary Koprowski, Stanley Plotkin, Beatrice Hahn and Robin Weiss.

It was, however, with some surprise that I came across Jon Cohen’s Science report of the 2002 International AIDS Conference in Barcelona, in the middle of which he wrote the following about the impact of recombination on phylogenetic dating:

“By isolating individual HIV-infected cells, Meyerhans and co-workers found evidence of at least two different variants – and as many as eight – a staggering 75% of the time. ‘It’s a really interesting and beautiful study,’ said Walker. The finding, published in this week’s issue of Nature, might help solve a long-standing puzzle: why multidrug resistance variants surface so quickly. It also raises serious questions about phylogeny trees that attempt to date the origin of HIV, all of which intentionally discard suspected recombinants to make the data interpretable.” [Science 2002; 297, 312-313]

For this paragraph, at least, I salute Mr Cohen.

Edward Hooper. October 14^th, 2004.

Officially, their stance is that they care little about the OPV/AIDS theory. They claim that it is but a minor annoyance that sometimes distracts them from their work for a few hours.

Sadly for them, the reality is rather different. Over the past four years, Hilary Koprowski and Stanley Plotkin have devoted a large portion of their time, and quite a bit of their incomes, to fighting the OPV/AIDS theory, and trying to ensure that it is suppressed in as many different fora (the halls of science, the media) as possible.

They are currently engaged in a new – and rather desperate – attempt to bury the OPV/AIDS theory once and for all. The major plank of this initiative involves making legal threats against broadcasters. This is supported by the sending of multiple letters to film festival directors and journal editors, enjoining them not to show, or publish, materials about the OPV theory. All these initiatives are based around false claims and misrepresentations.

Like its predecessors, this latest attempt will fail, because in all its essential elements it appears to be little more or less than an attempt to suppress the truth.

When it comes to defending their position, what doctors Koprowski and Plotkin especially like is the work of tame scientists like Beatrice Hahn, Bette Korber, Robin Weiss, Simon Wain-Hobson and Michael Worobey who, under the guise of making balanced scientific observations about the origins of AIDS, have falsely declared that the OPV/AIDS theory has been “destroyed” or “refuted”.

What Koprowski and Plotkin dislike are articles in the medical literature that either promote the OPV/AIDS theory, or which reveal that the theory has not, after all, been disproven. [For a recent example of the latter, see: Jim Moore, “The Puzzling Origins of AIDS”; American Scientist; November-December 2004; 92 (6); 540-547. Even though this article is actually quite strongly wedded to the “bushmeat plus contaminated needles” theory of HIV origin, Koprowski and Plotkin will still not like it, for it describes the OPV/AIDS hypothesis as one of four competing and viable theories of origin, and concludes: “headlines reporting the death of this theory remain premature”.]

However, what these two scientists really hate are films or television broadcasts about the OPV/AIDS theory. This is probably because they recognise the truism that a picture is worth a thousand words.

Presumably this is the reason for the latest legal onslaught by the two doctors (and by lawyers representing the two men) against television companies and film festivals which have shown (or are about to show) “The Origin of AIDS”, the 91-minute documentary that focuses on The River, and on my investigations since The River was published in 1999.

In recent months, I have been informed of several instances in which TV companies or film festivals have received legal threats from Koprowski, Plotkin, or their lawyers.

In one instance, a 67-page legal submission (a 15 page letter, and 52 pages of annexes) was apparently sent to a TV station.

Another television broadcaster was apparently given a finite number of days in which to broadcast what was effectively an on-air retraction – an opportunity which, it seems, it declined to take up. Some months later the company was informed by Koprowski’s lawyers that their client would not be proceeding further. Apparently no further explanation was given.

Since I only know of these legal initiatives at second-hand or third-hand, I shall not comment further about them, except to say that most of the so-called supporting evidence seems to be based around the tame articles written by scientists like Robin Weiss (“Polio Vaccines Exonerated”) and Michael Worobey (“Controversial Polio Vaccine Theory Refuted”), which are characterised by deliberate misrepresentation of the issues in the OPV/AIDS debate.

What this reveals is that as the vaccine-makers grow more and more desperate, their tactics get dirtier and dirtier.

It is all part of an ugly continuum, which reveals an uncomfortable link between scientific misrepresentation and full-scale legal bullying. Scientists like those mentioned above claim that they have refuted the OPV theory when they have not. [See accompanying article: Plotkin’s Chums (1).] They make over-grandiose claims, or misrepresent the significance of their data. Then attempts are made by doctors Plotkin and Koprowski to use these economies with the truth as a basis for legal action, and for intimidating broadcasters and festival directors so that (hopefully) they decline to show the film.

[Another analagous process has been occurring recently. This involves so-called “neutral scientists” who have, for whatever reason, decided to back Plotkin’s and Koprowski’s versions of events, and who then write identical letters to the directors of film festivals, claiming that the OPV theory has been disproved, and urging the festival directors to drop “The Origins of AIDS” from their schedules. The revelation of these letters shows that several of the leading scientists in this debate are acting dishonestly, and knowingly participating in an attempted cover-up. [Again, see “Plotkin’s chums (1)“.]

Hilary Koprowski has a long and ignoble history of trying to enforce his will on others through legal action, or the threat of legal action. In the United States, a land where the lawyer is king, he has enjoyed some successes in the past. How galling it must be to him that in the present circumstance, his normal method of shutting up opposition is not working!

I believe that, with respect to the “Origins of AIDS” debate, the legal threats made by (or on behalf of) doctors Koprowski and Plotkin are mischievous. I believe that their main intent is to intimidate and bully those with whom they do not agree into silence.

At present, the main thrust of their legal effort seems to be focussed on attempts to stop “The Origins of AIDS” documentary from being broadcast in the United Kingdom and the United States. I believe that they will not succeed.

Legal threats to the author of this piece

In the past, doctors Koprowski and/or Plotkin (or their lawyers) have twice threatened me personally, and Koprowski’s lawyers have once threatened each of my American and British publishers. Each of these legal threats has been seen off without too many problems: robust answers which contest the claims have been sent, and then nothing more has been heard from the good doctors.

However, last year Stanley Plotkin, who seems to be increasingly erratic, changed his tactics, and resorted to sending me a personal hand-written threat by post-card!

What deters doctors K & P from making further legal threats to myself is presumably the realisation that if they sue, I will certainly fight them – and that, unlike their good selves, I have rather copious evidence to support my case.

To begin with, I used to find their legal threats upsetting – and later on, they made me angry. These days, I just find them rather sad.

Just what do these two men think they are doing? Their scientific arguments are full of holes. They have repeatedly contradicted themselves in their own written statements. Their practice of leaning on European witnesses to persuade them to change key aspects of their testimony is now well documented. In Africa, their use of a proxy (Professor Dudu Akaibe) to do their bidding is again well-documented: he has used both his position (as Vice-Dean of Science at the University of Kisangani), and money (provided by Plotkin’s former employers, Pasteur Merieux) in an attempt to persuade some of our African witnesses to change their testimony, and he has kicked our African translator off his university course, without explanation.

Sadly, the more frightened these men get, the more lamentable their behaviour becomes. This same group of Plotkin’s helpers in Kisangani recently managed to obtain mid-1950s pathology samples from the old Stanleyville laboratory basement. Nothing publicly was announced about this, and all that one can say is that the intention in Plotkin’s mind was presumably not to discover a post-vaccination sample of HIV-1 and to announce it to the world. (The main fear, of course, is that if such an ancient sample of HIV-1 is discovered, it will instead be presented in another series, dating from before the days before the OPV trials.)

Stanley Plotkin promised more than three years ago to release into the public domain the letters and documents supporting his Royal Society articles. He has been reminded about this twice by Brian Martin. His excuses keep changing, but the promise has never been kept.

Once again, I call on Stanley Plotkin publicly to release these documents. Already, some of his source materials have been shown not to contain the evidence that he has claimed for them. One can only imagine the flaws and errors that must exist in those documents for Plotkin to continue to need to suppress them.

A Challenge to Dr Hilary Koprowski and Dr Stanley Plotkin

Here’s a challenge to the two of you good doctors. If you really are determined to disprove the OPV/AIDS theory, then for goodness’ sake go ahead and do so. Set aside the distorting and spinning, and the playground tactics that do you no credit at all.

Instead, just produce some real, substantive evidence to disprove the theory.

You see, gentlemen, I don’t think you have any such evidence. If you did have, you would have produced it long ago. The fact that you haven’t done so is not because the evidence has been mislaid (as Dr Koprowski claimed to me in 1993, when, extraordinarily, he said that papers pertaining to 1957-1968 got “lost in a move” to the Wistar Insttiute, a move which actually took place in 1957). It is because such evidence doesn’t exist.

Similarly, Dr Plotkin, I don’t think you will ever keep your oft-repeated promise to release the papers you cited at the Royal Society meeting. Why? Because they will reveal things that you would prefer not to be revealed.

Anyway, there it is, Dr Koprowski, Dr Plotkin. What are you going to do? Take up the challenge? Prove me wrong? Issue some more threats? Whatever you decide, I look forward to your response.

Untruths, misrepresentations and spin: the dubious methods and tactics used by Stanley Plotkin’s group in the “Origins of AIDS” debate

I think it is time for me to make a formal statement about the methods and tactics which Dr Stanley Plotkin, and various members of his support group, have been using in their attempts to counter the OPV theory, and to contest the “origins of AIDS” debate.

This support group officially includes Abel Prinzie, Jan Desmyter and Dirk Teuwen. Prinzie was working with CHAT vaccine at RIT and the Rega Institute in Belgium in the late 1950s; Desmyter was a medic working in the Belgian Congo from 1959 onwards; while Teuwen is a latter-day employee of the public affairs department of a Franco-American joint pharmaceutical venture, Aventis Pasteur-Merck, Sharpe and Dohme. Teuwen was apparently put on paid leave by Aventis Pasteur and placed at Dr Plotkin’s disposal, in order to assist his efforts in countering the arguments raised by The River.

In addition, there are several others, mainly Belgian, American and Congolese professors, who have collaborated with the Plotkin team at different times and in different ways since the publication of The River in 1999.

In recent times, Dr Plotkin, who likes to present himself as an honest broker in this debate, has leant heavily on the testimony of two scientists, Hilary Koprowski and Paul Osterrieth. For instance, an article by Dr Osterreith [Osterrieth, 2004] recently appeared in Vaccine, a journal which has Stanley Plotkin sitting on its editorial board. Accompanying Osterrieth’s article was an editorial by Plotkin [Plotkin, 2004] which was little shot of laughable as a piece of balanced analysis. For instance it claimed that the physical evidence presented at the Royal Society and Lincei meetings was “all against the OPV hypothesis” – a claim that, like many of Plotkin’s claims, contains considerably more braggadocio than truth. The Plotkin editorial was based on the unquestioning assumption that Osterrieth’s account was accurate. But Dr Osterrieth was hardly a “neutral witness” – for he was a close collaborator with both Koprowski and Plotkin on the chimpanzee research and CHAT vaccinations in Africa nearly half a century earlier – something that Plotkin’s editorial neglects to clarify. (Osterrieth was head of the virology department at the Laboratoire Medical de Stanleyville, LMS, from 1958 onwards, but he had been collaborating on the Koprowski/Courtois chimp research at Lindi from the time that he was first brought in to join the Stanleyville team, in July 1956.)

As for Dr Hilary Koprowski, these days almost every significant statement that he makes about his African research with chimps and CHAT vaccine can be proved to be untrue [see accompanying article]. The best interpretation that can be put on this is that he is now an elderly man, and that he is in profound denial about the possibility that his polio vaccine, as fed in Africa, may have sparked the AIDS pandemic. Dr Osterrieth, meanwhile, has changed his account on many occasions, as he continues to attempt to exonerate himself at all costs. On the key issues, his accounts conflict radically with those of every “neutral witness” whom I have been able to locate. The fact that Stanley Plotkin quotes so extensively from the flawed testimony of these two ex-collaborators indicates (a) an underlying disingenuousness and (b) paradoxically, a certain innate cautiousness, in that he continues to expend rather a lot of energy in trying to cover his own back.

---

There is now extensive evidence of a cover-up having occurred with regard to the CHAT programme in Africa, a cover-up which began in the 1950s, and which has intensified since attention has been drawn to that programme in recent years – first by Tom Curtis’s article in 1992 and more recently by my book The River (1999).

In particular, there is now evidence that Plotkin’s group has been inextricably involved in that cover-up. Members of the group have used improper methods on several occasions, including instances in which they have pressured or otherwise enjoined witnesses to modify evidence which they had previously given to me in interview. Since almost every one of these interviews was recorded on audio tape, I am in a good position to confirm the original statements that were made, and to raise significant questions about the modifications to that evidence that Plotkin and his group like to claim.

A selection of the dubious tactics which doctors Plotkin, Koprowski and their supporters have used in this debate are detailed below.

A. Pressuring institutions.

During the last five or more years, both Dr Plotkin and Dr Koprowski have repeatedly attempted to pressure both scientific institutions and publishing houses with respect to the Origins-of-AIDS debate.

According to reports from a reliable source, in late 1999, shortly after publication of The River, Dr Plotkin (then head of the Pasteur Merieux Connaught vaccine house, which was renamed Aventis Pasteur in that same year) wrote to the director of the Pasteur Institute in Paris, Dr Maxime Schwartz. Plotkin’s letter apparently proposed that the Institute could not remain silent or idle about my book. It is not clear whether Plotkin was proposing that an official statement be released, or that legal action be initiated, but the Pasteur Institute apparently declined to accede to Plotkin’s proposal.

[An aside. The Pasteur Institute has generally played an even-handed role in this controversy over the years, even if it seems to have leant towards the Plotkin/Koprowski position in recent times. For instance, in 1994 one of its journals, Research in Virology, published an early article by Elswood and Stricker which laid out the basic principles of the OPV/AIDS theory. Similarly in 1994, and again in 1997, its director of viral research, Luc Montagnier, told me in interview that he remained open-minded about the OPV theory and the origins of AIDS. By contrast, Aventis Pasteur and two of the other largest pharmaceutical companies in the world, Merck, Sharpe and Dohme and GlaxoSmithKline (which has absorbed RIT within its corporate embrace) have each publicly associated their corporate names with the Plotkin group, for instance by allowing those names to appear on the title page of that group’s “Postscript” in the Royal Society proceedings, published in 2001. This is perhaps not entirely surprising, for both RIT and the Pasteur Institute vaccine house (the forerunner of Aventis Pasteur) participated in polio vaccination programmes in Africa in the 1950s. It seems that these large drug companies take the position that the OPV/AIDS theory inherently threatens public confidence in vaccinations in general. Whatever, the fact that Aventis Pasteur has apparently helped support the Plotkin group financially (at least by funding Teuwen’s involvement) would seem to be significant.]

More recently, in late 2003, Dr Koprowski wrote to the president of the Accademia Nazionale dei Lincei in Rome, and complained about the publication of my article “Dephlogistication” [Hooper, 2003(A)] in the Accademia‘s journal, the Atti dei Convegni Lincei. This letter apparently made references to possible legal action, and demanded the right to reply to my paper in the Atti. The Accademia has since agreed to publish a reply by doctors Koprowski and Plotkin, and that reply will apparently appear in the October 2004 issue of another Lincei journal, the Rendiconti Lincei. I have already enquired of the Accademia whether I have the right to reply in turn to Koprowski’s response – and have been told that in principle I do. Because the Accademia has to date always acted with commendable fairness and even-handedness in this debate, I hope that it will agree to publish whatever reply I might find it necessary to submit.

Dr Koprowski has a reputation for being litigious, and on several occasions in the past has used legal action and the threat of legal action in order to gain advantage, for instance by frightening possible opponents into silence. One well-known example of this approach came with his legal action against Tom Curtis and Rolling Stone magazine in late 1992, in response to Curtis’s article entitled “The origin of AIDS: was it an act of God or an act of Man?” Eventually, after nearly a year of legal preliminaries and (allegedly) the expenditure by Rolling Stone of some $500,000 in legal fees, the magazine folded under the pressure and published a “Clarification” (which was not far from being an apology). It also paid Koprowski the symbolic fee of one dollar, and abandoned plans to run a follow-up article on the subject.

In similar vein, when the journal Nature Medicine was contemplating running an article about The River in 1999, and was polling views among scientists, one of its reporters received a phone call from someone who claimed to be a lawyer representing Dr Koprowski, who asked if she was aware that this topic had been the subject of litigation in the past. Whether or not for this reason, Nature Medicine did not proceed with the mooted article.

There are several other similar instances for which I have either hard or anecdotal evidence.

However, such pressure does not always succeed. For instance early in 1999, lawyers representing Dr Koprowski approached the CEO of Time Warner Inc., in an apparent attempt to delay, or stop, publication of The River. My US publishing house (Little, Brown & Co., which is owned by Time Warner), had already had very careful readings done on the book by both legal and scientific experts, and was satisfied that I could fully support the claims made in it. Little, Brown therefore declined the demands of Koprowski’s lawyers that he be given the opportunity to vet the passages relating to him prior to publication.

Similarly, my British publishers, Allen Lane/Penguin, withstood legal pressure from Koprowski’s lawyers in 2000 and 2001 [see below].

B. Pressuring individuals.

On two occasions in the year 2000, a member of Plotkin’s group, Professor Abel Prinzie, attempted to persuade a former Belgian sanitary agent, Hubert Caubergh, to repudiate what I had written in The River, and to deny that a version of CHAT vaccine prepared by RIT had been administered in Burundi in 1959-60. (RIT is a Belgian vaccine house that was founded in the 1950s and which has close links with the University of Leuven.) On February 9^th, 2000 and May 3^rd, 2000, Prinzie sent Caubergh typed letters along these lines, with his name pencilled in at the bottom, indicating where he was being invited to sign. Effectively, Caubergh was being invited to perjure himself. When I next saw him, Caubergh told me that what I had written about him and about this episode in The River was accurate. He described Prinzie’s approaches as “dishonourable”, and said that he had refused to cooperate with him. When Caubergh proved to be immovable, the Plotkin team presumably had to change its strategy, and at the Royal Society meeting in September 2000, Plotkin made no bones about the fact that RIT had produced one of the last versions of CHAT vaccine (lot DS101) to be fed in Africa (between December 1959 and March 1960); [Plotkin, 2001B. See also: Plotkin et al., 2001]. Dr Plotkin should not have worried, for in marked contrast to the CHAT vaccination trials in the Ruzizi Valley in western Burundi in early 1958, using OPV prepared in Stanleyville, there are no significant epidemiological correlations between the use of the Belgian-prepared vaccine in the rest of Burundi in 1959-60, and the earliest appearances of HIV.

Interestingly, since the Royal Society meeting (where I was asked questions about the improper approaches made to Hubert Caubergh at the press conference), Mr Caubergh has received a series of phone calls, letters and Christmas cards from Dirk Teuwen, who appears to be trying to limit the damage caused by Prinzie’s approach. Teuwen has also met with Mr Caubergh twice. Fortunately, Mr Caubergh has spoken about this episode several times on tape, and has promised that if Plotkin or Koprowski should ever carry through their threats to take legal action against me, he will not stand idle.

Sadly, there were few other protagonists from the 1950s who proved to be as principled as Hubert Caubergh, and who felt able to withstand such pressures. Many of the others who were approached found it easier to “adapt” their stories on key points, so that they conformed to the Plotkin group’s version of events. This of course still leaves Plotkin and his colleagues needing to explain why so many of these witnesses apparently modified their accounts on key issues such as what happened to the Lindi chimps, and whether chimpanzee tissue culture was ever prepared at Stanleyville. They like to insinuate that I fabricated, misreported, or misinterpreted the original evidence. The audio recordings of the interviews (and my notebooks) prove otherwise.

I now have evidence of several instances in which improper approaches have been made by members of the Plotkin group to witnesses, in a bid to persuade or pressure them to modify their stories. The continuing emergence of further examples suggests that there are probably yet other instances in which the full story is yet to come to light.

In addition, since 1995, I myself have been threatened with legal action three times by lawyers representing Dr Koprowski and once by a lawyer (also acting for Koprowski) who was representing Dr Plotkin. I have always replied robustly, and they have never made good on any of their threats. This is hardly surprising, in that the OPV theory is backed by hard evidence, whereas their own versions of events are not – something that would readily be revealed in a court of law.

Dr Koprowski’s most recent approach is worth mentioning here, not least because it was presented in an unusual manner. In December 2000, a lawyer acting on his behalf wrote both to me and to my British publishers, Allen Lane/Penguin, asserting that overwhelming evidence against the OPV/AIDS theory had been presented at the Royal Society conference. He then stated that Dr Koprowski could sue, but instead proposed an alternative: the setting up of a medico-legal panel to which both sides could present their evidence, and which could then “adjudicate on the OPV theory”. The end of the letter stated that if no response was received, then Dr Koprowski would have no alternative but to sue. A lawyer representing Penguin UK replied, robustly contesting each of the claims made in the letter. She expressed some surprise at the idea that a quasi-legal panel could resolve a scientific debate, but nevertheless requested further details, such as who was being proposed to fund the panel, and to sit on it. No reply was ever received from the Koprowski camp.

In yet other instances which are not so crucial to the story, a rather different process may have come into play, one which involves solidarity between professional colleagues, a tendency for which the medical community, in particular, is well-known. I believe that some of those who initially gave testimony to me may, after being approached by the Plotkin team, have experienced some unease about having said things which (they now felt) might have placed their colleagues in a difficult position. Some of them, while not prepared to retract their original statements, may have been prepared to adapt their statements in such a way that they did less “damage”. There are several instances in Plotkin’s Royal Society papers in which, I suspect, this professional solidarity factor may have played a role.

C. Malpractice and dubious practice.

Let me now return to the instances of malpractice (and questionable practice) by members of Plotkin’s group. {Certain of the other examples have already been described in previous papers: the approaches made to doctors Ninane and Bugyaki are described in Dephlogistication [Hooper 2003(A), pages 203-206], while the treatment of some of the Congolese witnesses is described in the postscript to my February 2004 paper entitled “Robin Weiss, professor of virology, doctor of spin”.}

Many witnesses have been sent pretyped statements with their names pencilled in at the bottom, where they are meant to sign. Plotkin has defended this as an appropriate technique for gathering testimonial evidence, but he has completely failed to address the fact that in cases such as Caubergh’s, the technique has clearly been abused, in that the witness has been invited (indeed, badgered) to put a signature to a false statement.

In similar fashion, at the Royal Society conference, in the material which was circulated to the press, Stanley Plotkin included a map which he sourced to my book The River, and which featured the OPV vaccination sites and early cases of AIDS in central Africa. The only problem was that Plotkin had decided to add to the map two extra AIDS cases from Kikwit which, he claimed in his speech, were the very ones that were most crucial to my argument. These cases do not feature in the maps in my book (which cover early AIDS cases up to 1980) because they occurred in 1986 and 1987. In this instance Plotkin first misrepresented my evidence, and then criticised me on the basis of his flawed version of that evidence: a classic case of setting up straw men to shoot at.

Another example of dubious practice is revealed in the TV documentary, “The Origins of AIDS”. A typed statement which had apparently been signed by Paul Osterrieth on February 28^th, 2000 and forwarded to Plotkin, ends with the following hand-written words: “I also want to state very clearly that I never sent chimpanzee kidneys to the WISTAR Institute, Philadelphia”. [A copy of this witness statement was faxed from Plotkin’s office, in response to an enquiry made in October 2000.] Plotkin’s “Postscript” article cites Osterrieth as making a very similar written statement on October 15^th, 2000: “Chimpanzee kidneys were never sent to the Wistar Institute, only to Dr Deinhardt at his demand” [Plotkin et al., 2001]. Yet in the speech which he gave at the conference in September 2000, and which he later submitted (slightly adapted, but not with respect to this sentence) for publication in the conference proceedings [Osterrieth, 2001], Dr Osterreith states the following: “It is true that six minced chimpanzee kidneys were sent to the Wistar Institute at the request of Fritz Deinhardt…” The latter sentence, written in the passive tense, carefully avoids providing an identity for the sender. However, Osterrieth has previously acknowledged that it was he personally who dispatched chimpanzee kidneys to Philadelphia.

This means that two directly conflicting accounts, both sourced to Osterrieth, appear side by side in the Royal Society proceedings, on pages 825 and 839. Where in Philadelphia did Dr Osterrieth send these chimp kidneys? Was it via the Wistar Institute or not? When writing signed statements for Plotkin, he insists that he didn’t send chimp kidneys to the Wistar; when delivering his own speech (and, some months later, submitting his own paper), he states that he did. At the very least, this is evidence of real sloppiness by both Osterrieth and Plotkin. But it may well be more. It may be that Osterrieth is revealing that he actually did send chimp kidneys direct to the Wistar Institute, and that those intended for Deinhardt (at the nearby Children’s Hospital of Philadelphia) were forwarded to him out of the Wistar’s supply. This is doubly significant, because, from the description in the original documents, it is apparent that the “minced chimpanzee kidneys” alluded to by Osterrieth in 2000 actually constituted primitive, untrypsinised chimp kidney tissue cultures.

Apart from this, the words added at the end of Osterrieth’s typed statement of February 28^th, 2000, are clearly not in Osterrieth’s own hand. We do not know who wrote them, or, indeed, when they wrote them. They could have been added before Osterrieth signed, or afterwards. This further example of sloppiness raises additional doubts about the reliability of Plotkin’s witness statements. This is especially significant in the light of the fact that Dr Plotkin has failed to honour his repeated promises to release those statements for public inspection [see below].

These are merely examples of the approaches and techniques routinely used by the Plotkin team in their attempts to disprove the evidence that I have carefully assembled and reported over the last twelve years. Many of these are careless and unprofessional, but in several instances they are much worse than that. In particular, the attempts to persuade witnesses to perjure themselves are not only dishonourable, but also dishonest.

The result is that much of the testimonial evidence that Plotkin puts forward in a bid to disprove the OPV theory is false, while much of the rest is unreliable.

D. The campaign of misinformation.

Plotkin has failed to address the vast majority of the evidential points presented in The River, such as (to quote but one) the fact that in three published papers in 1956 and 1957, Hilary Koprowski wilfully misrepresented in the medical literature which tissue culture he was using as final substrate for his OPVs. (He wrote that he was using a tissue culture of chick embryo when he was actually using some variety of primate kidney.) Instead of making a sincere attempt to respond to my claims, he has instead focused on trying to score points (or to engender confusion) on specific issues, in many instances basing his ripostes on questionable witness statements.

This is a classic misinformation technique: firstly to present “evidence” that raises doubts about the legitimacy of the opposition’s case, and when that is not possible, to try to obscure events behind a smokescreen of confusion and uncertainty.

I have to admit that the approach used by the Plotkin group, tacitly or openly supported by several of their colleagues, has enjoyed considerable success, at least on the level of the public relations battle. The fact that they have managed to construct a defence is crucial, even if it is a defence based on misrepresentations and falsehoods. For they can now point to the articles they have had published in the scientific literature, and claim to their peers that they have answered the claims made in The River, or in Dephlogistication. Only those who take the trouble to check more carefully (and not even all of them) come to realise that Plotkin’s defence is extremely flimsy.

Some of the major scientific journals (Nature in particular, over which Robin Weiss exerts undue influence on the subject of AIDS) have acquiesced in this process, and continue to publish commentaries that focus on the denials, while failing to report the original arguments. In comparison to the numbers who read Nature and Science, it is clear that relatively few scientists have read either The River or the papers I have published since 1999, and so it is that many “neutral scientists” meekly accept the perceived wisdom that the OPV/AIDS theory has been disproved. In reality, nothing could be further from the truth.

So it is that a cover-up has been effected about the origins of the major medical tragedy of our times. When the full story is told (as, indeed, it will be told), the ignominious roles played by several scientists and scientific journals will become embarrassingly apparent. One is left to wonder whether the primary motive in the minds of some of those involved is not a shamelessly egotistical one: “Let it not be in my lifetime”.

E. Accusations and threats.

The responses of the Plotkin group to my recent findings are also rather interesting. The early published responses to my book by Plotkin, Desmyter and Teuwen contained sections which were both untrue and abusive. An example was Plotkin’s parting shot in an article in Clinical Infectious Diseases, a journal for which he once again sits on the editorial board. “The River“, he wrote, “is a house of cards built on a swamp of conspiracy theory, unsubstantiated insinuations and character assassination. It is fundamentally meretricious, and does not withstand critical analysis.” [Plotkin, 2001(A)] Plotkin submitted virtually the same article to the Royal Society volume on “Origins of HIV and the AIDS Epidemic” [Plotkin, 2001(B)], but the Society’s lawyers apparently insisted that this section be omitted on legal grounds.

Since then, Plotkin appears to have received some training in both public relations and legal matters. But now and again, the old unvarnished Stanley Plotkin still emerges. Three months after the appearance of my “Aids and the Polio Vaccine” article in The London Review of Books [Hooper, 2003B], Plotkin apparently came to England, and visited Wells cathedral, just a few miles from my house. He did not contact me for a face-to-face chat, however. Instead, he sent me a post-card. The front of the card showed one medieval figure beating another over the head with a stick, and the caption read “Punishment of the apple-stealers”. The message read: “Dear Ed, Thinking of you. Stanley Plotkin”.

One could view this card either as a black joke, or as a threat. Personally, I view it as a bit of both. However, it does need to be seen in context. Stanley Plotkin’s last communication with me, prior to the post-card, was the threatening letter sent through his lawyer. It will be interesting to see what he does next.

F. More missing documents.

At the end of his “Postscript” paper, published in the Philosophical Transactions of the Royal Society of London in July 2001 [Plotkin et al., 2001], Plotkin writes the following: “Letters cited in this paper will be deposited in the library of the College of Physicians of Philadelphia or the University of Leuven.” This was a strangely vague promise, but by May 2003, Plotkin had still not honoured it. At that time, in response to an enquiry by Professor Brian Martin, he indicated that he was currently too busy to do the sorting and copying, but would hopefully be able to do it during July or August 2003. He finished by promising: “I will make it a priority to deposit the documents this year”.

In February 2004, Brian Martin again e-mailed Stanley Plotkin to enquire whether the documents had been deposited, and Plotkin replied that they had not been. He wrote that his secretary had “been devoting her spare time to annotating the documents”, but added that “to be frank” there was now an additional problem, which was the “renewed activity of Ed Hooper”, which “requires that I have access to the documents, further slowing the process”.

This is a surprising and revealing statement, for it fails to address the simple fact that Dr Plotkin must surely already have copies of these letters, which would allow him to continue working with them. It is hard to think of any conceivable reason why he would need to continue working with the original letters – unless, of course, he has something to hide.

It is now more than three years since Plotkin made his written promise to deposit the “letters cited in this paper” (ie the originals, not the copies) in one of the two stated libraries for public viewing. Claiming pressure of work, or the continued need to have access to the documents, is a totally inadequate excuse for failing to honour his word. This means that although my source materials are available for viewing upon request (and indeed have been viewed by several interested persons), Dr Plotkin appears to be keeping his source materials hidden from public view.

The flaws and dichotomies which have been noted in some of the few documents which Dr Plotkin has released publicly (eg the map of CHAT versus AIDS in Africa that was supposedly sourced to my book, and Osterrieth’s February 2000 statement, both mentioned above) raise questions about his reliability and integrity, as does his continued failure to honour his promise on this issue.

I believe that Plotkin is stonewalling. Whatever, I am hereby calling on him to honour his promise, and deposit the letters for public viewing. But I am doing more than that. I hereby call on him to deposit all the letters cited in both of his Royal Society articles – not just those relating to his “Postscript”, but also those relating to his first article [Plotkin, 2001(B)] – in one of the two libraries he mentions, and to do this by the end of the year 2004. I believe that at this stage, doing this will be the only way in which he can allay concerns about the reliability and authenticity of these documents.

Until he does this, then it will be clear to many observers that Dr Stanley Plotkin is unable (or unwilling) to produce the “evidence” which he claims supports his position.

G. My response to Plotkin’s Royal Society papers.

Shortly after the Royal Society meeting, I posted my preliminary response to the two speeches that were delivered by Plotkin and Koprowski at the Royal Society meeting on Brian Martin’s web-page on “Polio vaccines and the origins of AIDS” [Hooper, 2000]. Even at that stage, it was apparent that their two speeches featured a surprisingly large numbers of inaccuracies and misrepresentations.

During the all but four years that have passed since that meeting, many more flaws and untruths have come to light – both in the aforementioned papers, and in the Postscript that Plotkin’s group was allowed to include in the published proceedings of the Royal Society meeting. I have been waiting to inspect the source materials for Plotkin’s papers, but as it becomes increasingly apparent that Plotkin is doing all he can to avoid or delay making these available, I must now consider whether to release my more formal response to the Plotkin/Koprowski papers without seeing Plotkin’s source materials.

For now, it suffices that I should reinforce what I have stated previously. The papers by doctors Plotkin and Koprowski that were published in the Philosophical Proceedings of the Royal Society of London, Series B, 2001, Volume 356, are full of inaccuracies, errors and untruths. They represent an attempt to construct a defence that is based on false claims and fabricated evidence.

Hopefully the revelations in the MFP/Galafilm television documentary, “The Origins of AIDS”, will raise questions in the minds of at least some of those who have previously been happy to accept the statement with which Robin Weiss ended his commentary on this debate in the pages of Nature: “Some beautiful facts have destroyed an ugly theory” [Weiss, 2001].

In September 2001, at the Lincei meeting, I challenged Dr Weiss to produce just one such “beautiful fact”. He was unable to do so then, and he is still unable to do so today – as are those he chooses to defend, such as doctors Koprowski, Plotkin and Osterrieth.
