Over the weekend, I chilled out a bit, at least as far as the blog was concerned. I won’t make too much of a secret of it, but thanks to the new policy of the new owners I have a decision to make. In the meantime, while I’m dithering, you, my readers, were deluging me with requests. Well, it wasn’t exactly a deluge. Maybe three or four e-mails. But, hey, over a dull holiday weekend, when I spend most of the time either working on a grant or working in my yard? That’s a deluge! Never let it be said, either, that I don’t give the people what they want (usually, at least). So what are the latest depredations, antics, silly statements, and outright flaming stupidities that have caused my readers to plead with me–nay, beg me–to unleash the hounds and provide a heapin’ helpin’ of that not-so-Respectful Insolence that you all know and either love or hate upon an unsuspecting advocate of pseudoscience?

Well, it starts with a website and blog known as SANE Vax.

If you’ve been in the biz a while, as I have, you can tell right away from the very name of this website exactly where its creators are coming from. Here’s a hint. It’s not the mission that the website claims that it is, which is stated thusly:

The Sane Vax Mission is to promote Safe, Affordable, Necessary & Effective vaccines and vaccination practices through education and information. We believe in science-based medicine. Our primary goal is to provide the information necessary for you to make informed decisions regarding your health and well-being. We also provide referrals to helpful resources for those unfortunate enough to have experienced vaccine-related injuries.

Oh, no. SANE Vax didn’t go and claim that its members believe in science-based medicine, did it? I wonder if Steve Novella knows that anti-vaccine activists are misappropriating the term he and I promote as how medicine should be based in science. Science-based medicine. You keep using that term. I do not think it means what you think it means. In any case, SANE Vax appears to be anti-vaccine to the core, which should be obvious from its name. Obviously, if its creators think they’re promoting “sane vaccination,” by implication they very likely think that the current vaccination schedule is not sane. Further supporting the rather mind-numbingly obvious conclusion that SANE Vax is indeed anti-vaccine are videos featuring Andrew Wakefield, Barbara Loe Fisher, and other luminaries of the anti-vaccine movement, as well as a Vaccine Victims Memorial, the latter of which is a page taken right out of the playbook of the National Vaccine Information Center (NVIC), one of the oldest anti-vaccine groups still in existence. Meanwhile, it’s list of “vaccine groups” contains all the usual anti-vaccine suspects, like the Australian Vaccination Network, Age of Autism, ThinkTwice, Generation Rescue, and Impfschaden (discussed just last week).

I also don’t believe for a minute that SANE Vax is, as it bills itself, a “vaccine safety” group. For one thing, in the comments of the two SANE Vax posts I’m about to discuss, Australian skeptic Peter Bowditch shows up to ask, “Which vaccines are “necessary” and “effective” to match the ‘N’ and ‘E’ in SANE?” He has yet to receive an answer. This fulfills one of my key criteria of an anti-vaccine activist in that when, after hearing her piously pontificate that she is “not anti-vaccine,” you ask her which specific vaccines she supports and get either no answer or dancing around the question with no real answer.

So what’s got SANE Vax in an uproar? DNA. But not just any DNA. Recombinant DNA. But not just any recombinant DNA. HPV recombinant DNA. Take a look at some posts that appeared on the SANE Vax blog over the weekend and very early this morning:

Oh, noes! DNA! The horror…the horror.

Does this sound familiar? It should. It’s almost exactly the same fear mongering nonsense that Joe Mercola and Helen Ratajczak used to try to claim that homologous recombination of fetal DNA in vaccines with the DNA in babies’ brains resulted in autoimmune inflammation that led to autism. In this case, the vaccine is the HPV vaccine, but the arguments are merely a variation on the same stupid theme. Here’s what SANE Vax is claiming:

SANE Vax Inc. contracted with an independent lab to test for contamination and found HPV recombinant DNA (rDNA) in 13 vaccine vials. The Gardasil vials with different lot numbers were from New Zealand, Australia, Spain, Poland, France and three states in the U.S. 100% of the samples tested positive for the presence of the genetically modified HPV DNA.

Dr. Sin Hang Lee, a pathologist at the Milford Hospital pathology laboratory well-known for using cutting-edge DNA sequencing for molecular diagnoses, was initially contracted to examine a single sample of Gardasil for possible contamination. This sample tested positive for recombinant HPV-11 and HPV-18 residues, both of which were firmly attached to the aluminum adjuvant.

Wow. Sounds pretty scary, doesn’t it? Actual HPV DNA! But not just any DNA. Oh, no. We’re talking recombinant HPV-11 and HPV-18 residues, which–horror of horrors!–were attached to the evil aluminum adjuvant! Stop the factories! Stop injecting our little girls with that evil vaccine whose only purpose is to encourage them to go out and have unprotected sex, knowing that they won’t get HPV!

Now hold on just a minute.

Let’s take a look first. First of all, one notes that there is not a single scientific paper–or even scientific report–describing the methodology used and the specific tests used. Oh, sure, in SaneVax’s letter to the FDA, Norma Erickson provides an actual picture of an actual graph from an actual DNA sequencing run in order to look all science-y, but then she also says:

The SANE Vax Inc. data, including the electropherograms of short target sequencing used to validate the HPV DNA detected in the thirteen (13) Gardasil samples, each with a different lot number, are available for your review, provided appropriate safeguards are in place to protect the proprietary processes and information utilized by our laboratory to test the samples.

Protect the “proprietary” processes used to test the samples? Why on earth does the Milford Hospital Pathology Laboratory need to use “proprietary” processes to test for recombinant DNA in the vaccine? Whenever I see a result like this attributed to proprietary, non-transparent methodology, it sends up huge red flags, particularly when it comes to doing something like detecting DNA contamination. I could do it in my own laboratory using simple polymerase chain reaction (PCR) and then sequencing the DNA sequences (if any) that I managed to amplify up! No need for anything proprietary, other than choosing the PCR primers properly! I could use PCR kits right off the shelf and any of a number of PCR machines, either in my lab or the spiffier, newer machines in other labs. Again, the key is choosing the right primers and working out the right conditions, but none of that is anything particularly difficult, although testing different conditions can turn into the drudgery of trial and error.

Before I get to the significance (or, far more likely, lack of significance) of this finding. Let’s take a look at the methodology. I did a bit of Googling for our Dr. Sin Hang Lee, and it turns out that he has a rather–shall we say–interesting history. It turns out that Dr. Sin Hang Lee is rather well known in the Lyme disease community for having apparently invented a new test for Lyme disease. That may or may not be dubious. What is definitely dubious is that he’s also teamed up with SANE Vax to offer an HPV genotyping test announced on the quackery-promoting NaturalNews.com. This latter link actually suggested to me what Dr. Lee’s “proprietary” methodology might be, as it’s described as “nested PCR with short target DNA sequencing for HPV genotyping.” Going back to look at his Lyme disease DNA test, I find this paper, which also used nested PCR to detect sequences from the Lyme disease spirochete Borrelia burgdorferi.

So what is nested PCR? As readers might recall, PCR is a method to amplify nucleic acid sequences, like those of DNA or RNA. I described it in more detail in the context of explaining how the laboratory Andrew Wakefield used produced so many false positive results. I also described how the greatest power of PCR also leads to the greatest difficulties in its usage, namely its extreme sensitivity. PCR is so sensitive that it’s very, very easy to amplify a contaminant or for the primers to bind to (and thereby amplify) DNA sequences other than the one of interest. This problem goes double (or even quadruple) for nested PCR. The reason is that nested PCR involves using one set of primers to amplify a DNA sequence, and then taking some of the resultant reaction mixture and using a second set of primers that amplifies a smaller sequence within the sequence amplified in the first PCR run. The process is illustrated below. First, here’s routine PCR:


And here’s nested PCR:


The usefulness of nested PCR is two-fold: First, because two different sets of primers are used, specificity is increased and the amplification of contaminants decreased because, although there might be contaminants amplified in the first PCR run, it’s very unlikely that any of the unwanted PCR products so amplified contain binding sites for both of the new primers used in the second PCR run. Second, nested PCR can be very, very sensitive, even more sensitive than “simple” PCR, depending upon the number of amplification cycles used in each PCR step. It’s that sensitivity that allows nested PCR to amplify very tiny amounts of target sequence.

Which brings me to the lack of any detail in this report.

Let’s say, for the moment, that Dr. Lee did everything right and actually did detect a bit of recombinant DNA from the HPV DNA used to make the vaccine still remaining in the 13 vials of vaccine he tested. Does this matter? One factor to consider is how much DNA was present, which was almost certainly very, very little, given that it took nested PCR to detect it. However, we don’t know how much was detected, because nothing on the SANE Vax posts tells us enough to let us know approximately how much was detected. Given that, and given the probably minuscule amount of DNA detected, even assuming these aren’t false positives, there is no justification for statements like this:

In an effort to help her now very sick daughter the mother went to an MD practicing naturopath who conducted a toxicity test that eventually found HPV DNA in the girl’s blood. The significance of this finding is that it is highly unusual to find HPV DNA in the blood. HPV, if present in the body, exists in the epithelial (skin and mucosa) membranes. HPV or its DNA, by itself does not survive for any great length of time in the bloodstream. Why was the HPV DNA in her bloodstream two years post-vaccination?

My answer would be: Probably because the naturopath, like most naturopaths, didn’t have a clue what he was doing or how when he “detected” HPV DNA in the blood. If Dr. Lee had clue one, that’s what he would have said. But he didn’t. He said this instead:

According to Dr. Lee, “‘Natural HPV DNA does not remain in the bloodstream for very long. However, the HPV DNA in Gardasil™ is not ‘natural’ DNA. It is a recombinant HPV DNA (rDNA) – genetically engineered – to be inserted into yeast cells for VLP (virus-like-particle) protein production. rDNA is known to behave differently from natural DNA. It may enter a human cell, especially in an inflammatory lesion caused by the effects of the aluminum adjuvant, via poorly understood mechanisms.

“Once a segment of recombinant DNA is inserted into a human cell, the consequences are hard to predict. It may be in the cell temporarily or stay there forever, with or without causing a mutation. Now the host cell contains human DNA as well as genetically engineered viral DNA.”

This is utter nonsense. First off, as I described before, it’s not a trivial matter to get recombinant DNA into human cells and expressing the protein that its sequence codes for. It’s worth repeating what I described when I first encountered this idiocy in a different context. For rDNA to do what Dr. Lee worries about, the minute amount of rDNA in the HPV vaccine would have to:

  • Find its way into human cells in significant quantities, which is highly unlikely given the tiny amount that, even in the worst case, is there.
  • Express the protein that it codes for, which would require that the DNA be intact, complete with its promoter and regulatory regions. Again, this is incredibly unlikely, given the amount of DNA we’re talking about unlikely.

I actually have some experience with direct intramuscular injection of DNA to try to get gene expression. Indeed, some of the earliest experiments studying gene regulation in rat muscle by direct injection of plasmid DNA were performed in the laboratory where I did my PhD work, and even now I know investigators who are working on DNA vaccines. It takes microgram quantities of intact plasmid DNA, and even then expression levels are low without special help, such as the “gene gun” or other techniques. Also remember that the HPV vaccine is made of non-infectious HPV-like particles, which are basically formed from the L1 surface protein of the HPV virus, which makes the outer coat of the virus particle. Even in the highly unlikely situation that the tiny amount of recombinant DNA alleged to be left behind in Gardasil could get into human cells and actually make detectable amounts of VLP, the only place it’s likely to be able to do that is in the muscle in the immediate vicinity of the injection site.

None of this prevents SANE Vax from laying down some serious extrapolating beyond science and reason:

SANE Vax Inc. wants to know how many adolescents who have suffered adverse reactions post Gardasil vaccination have HPV DNA in their blood. What are the medical ramifications should HPV DNA remain in the bloodstream for an extended period of time?

Does the aluminum adjuvant become the carrier for HPV DNA causing said DNA to remain in the blood and/or organs for an extended length of time?

Since viral DNA cannot replicate by itself (it needs a host cell) what happens if genetically engineered viral DNA enters a human host cell?

In a followup post, SANE Vax demands:

  • What autoimmune-related disorders could result from this contamination?
  • Is it possible for this contamination to initiate gene mutations which may lead to cancer?
  • What genetic changes (mutagenesis) could occur should the residual HPV DNA enter and begin reproducing in a human cell?

All of this is putting the proverbial cart before the horse. First things first. Before anyone takes the claim that there is HPV DNA left in HPV vaccines and, more importantly, before anyone does anything (if, indeed, anything even needs to be done), an external laboratory needs to replicate Dr. Lee’s results. Interestingly, SANE Vax now appears to be backpedaling a bit:

The HPV DNA testing was performed by Dr. Sin Hang Lee, a pathologist at the Milford Hospital pathology laboratory known in using cutting-edge DNA sequencing for molecular diagnoses. This methodology was first reported to the FDA in 2006 and has been published in various peer-reviewed scientific journals, stated Erickson.

Well, well, well, well. If Dr. Lee’s methodology was reported to the FDA in 2006 and has been published in peer-reviewed scientific journals, then what’s “proprietary” about it, and why is he so reluctant just to publish his results regarding the HPV vaccine? I challenge Dr. Lee and SANE Vax to publish in full the complete methodology used to make this finding, along with the results. I find it most ironic that SANE Vax calls on the FDA and Merck to be “transparent,” but nothing about the way SANE Vax has publicized its “results” is in the least bit transparent, nor has Dr. Lee’s methodology to obtain these results been peer-reviewed. Worse, in the SANE Vax letter to the FDA, SANE Vax demands assurances that the FDA will protect Dr. Lee’s proprietary methodology before it will provide the FDA with its results. The hypocrisy and intellectual dishonesty are staggering. More importantly, without SANE Vax’s alleged results being available to the FDA and independent scientists to examine, all we have to support the claim that there is recombinant DNA in the HPV vaccine is the word of an anti-vaccine group.

Color me not particularly worried. Until there is independent verification, it’s utterly pointless even to worry about these other questions because the source, being rabidly anti-HPV vaccine, is suspect, and there is no way to determine if the methodology used is valid and not likely to produce false positives. After all, the HPV vaccine is tested for the presence of recombinant DNA, and it’s below the limit of detection of standard techniques; otherwise, Merck, the FDA, and other scientists would have detected it before. Only a scientist affiliated with an anti-vaccine group can seemingly detect it. Moreover, even if Dr. Lee did detect what previously couldn’t be detected before, clearly he’s detecting rDNA at such a low quantity that it’s doubtful that it would be harmful in the least. Certainly, given such a tiny amount of rDNA, it’s downright silly to talk about whether the aluminum adjuvant could somehow become a “carrier” for HPV DNA that allows it to be present in the blood for an extended period of time. Given that the HPV rDNA couldn’t replicate, the law of conservation of mass is enough to dismiss this concern as ridiculous, because it would take far more DNA than could possibly be in the adjuvant to produce detectable levels in the blood for long periods of time.

Maybe Dr. Lee should be come a homeopath. He seems to think that the more the HPV DNA is diluted, the stronger it becomes.

    Sane-Vax is now reporting bad news for Dr. Sin Hang Lee, the person who did the analysis. “his position as director of the laboratory was summarily terminated along with his employment relationship at Milford Hospital on December 13, 2010 and he has been prevented from using the hospital’s laboratory to continue his testing and research there ever since that time.”

    We are supposed to believe this is a giant conspiracy theory. But look at the dates. He was terminated almost a year ago, well before Sane-Vax began to publicize these “results”.

    “I wonder if she hates all vaccines, or just hates Gardasil because it’s associated with people at some point in their lives having sex.”

    I read through the first “article” (an interview of Reisman) featured on the whale.to site (Salvo, Spring ’07) and of course Reisman is against Hepatitis B shots, as well.

    FYI ToddW said

    I get that you are terrified of Gardasil. It has an aluminum adjuvant (which has decades worth of safe use in humans in the U.S.). It might cause a serious allergic reaction (which is easily managed with an epipen and so, under normal circumstances, is a relative non-issue).

    Type I allergy is a classical Th2-driven hypersensitivity disease based on IgE recognition of environmental allergens. Exposure of allergic individuals to exogenous allergens leads to immediate type inflammation caused by degranulation of mast cells via IgE-allergen immune complexes and the release of inflammatory mediators, proteases and pro-inflammatory cytokines.

    However, allergic inflammation can occur and persist in the absence of exposure to exogenous allergens and might paradoxically resemble a Th1-mediated chronic inflammatory reaction.

    We summarize evidence supporting the view that autoimmune mechanisms might contribute to these processes.

    IgE recognition of autoantigens might augment allergic inflammation in the absence of exogenous allergen exposure. Moreover, autoantigens that activate Th1-immune responses could contribute to chronic inflammation in allergy, thus linking allergy to autoimmunity.
