As hard as it is to believe after seven and a half years of existence and nearly 2,400 posts on SBM, every so often, something reminds me that we here at SBM haven’t discussed a topic that should be discussed. So it was a couple of weeks ago, when I saw a familiar name in a news story that wasn’t about vaccines. You might recall a news story last month when a shadowy group with ties to radical antiabortion groups, the Center for Medical Progress, led by a man named David Daleiden, ran a highly questionable “sting” operation (complete with fake IDs) to “prove” that Planned Parenthood was selling aborted fetuses for medical research.
While reading news stories about Daleiden and CMP, I came across a familiar name, a name that many of us who discuss antivaccine misinformation are familiar with. I’m referring to Theresa Deisher, founder of the Sound Choice Pharmaceutical Institute. It turns out that Deisher helped to prepare Daleiden for his role as a biomedical representative that he assumed in order to deceive representatives of Planned Parenthood. She taught him how to talk the talk and walk the walk, so to speak, so that he was convincing as a representative of a biomedical research firm.
I can hear you asking: So what? What do Daleiden and CMP have to do with vaccines? It’s not CMP per se, but Deisher who is relevant. The reason that Deisher is so relevant to Science-Based Medicine (SBM) is because she is one of the foremost promoters of a particularly pernicious form of antivaccine misinformation that tries desperately to create a religious basis to oppose vaccines with antivaccine activism. It is a form of misinformation designed to deceive those who believe abortion is a moral wrong into thinking that vaccines, too, are a moral wrong because some of the viruses used to make specific vaccines are grown during the manufacturing process in cell lines derived from human fetuses decades ago. But Deisher goes one huge step beyond just guilt by association for vaccines. She is, as the news story cited above notes, the foremost promoter of a related and equally pernicious form of antivaccine information that claims that DNA from the fetal cell lines used to grow vaccine strains of viruses is a cause of autism. The truly depressing thing about Deisher is that she is, in fact, a real scientist (or at least was).
In any event, it occurred to me that, although I’ve mentioned Deisher briefly before in the context of the Disneyland measles outbreak, I’ve never deconstructed her antivaccine misinformation in detail here. Yet, her work is often cited by antivaccine activists to persuade those whose religion tells them abortion is morally wrong that they shouldn’t vaccinate their children by adding to the false claim that somehow “fetal parts” are used in the making of vaccines the even more false claim that fetal DNA somehow gets into the brain, recombines with the DNA in neurons, and causes autism. She’s also just released what appears to be a new paper claiming to show how fetal DNA causes autism. The confluence of her name coming up in stories about CMP and Planned Parenthood and her release of this new “paper” makes this a perfect time to write about Deisher.
