I've written before about how the anti-vaccine movement regularly gets the science wrong (see, for example,
here and
here). Most often, it involves how they interpret (or, rather, misinterpret) studies that they think support their view that vaccines are the root of all evil, causing all manner of disorders. They regularly misrepresent and torture the scientific literature to fit their agenda. But occasionally, it involves actually attempting to do science themselves, the latest of which being a study
[Edited to Add: this study has been fully retracted by the journal.] recently published by Vaccine Injury Compensation Program petitioner, Brian Hooker, PhD and funded by the anti-vaccine group Focus Autism. This study has been examined by an
epidemiologist,
another epidemiologist, and a
cancer researcher. The players have also been examined by a
dyslexia consultant and autism advocate (see also
here). This study, in addition to being of questionable validity, has spawned quite the brouhaha among anti-vaccine activists. In short, Hooker took a dataset that was analyzed by a group of
CDC investigators. Their finding was that age at first vaccination with MMR did not appear to [

affect the risk of be associated with autism [
ETA: cases (those with autism) were no more or less likely to have been vaccinated with MMR than controls before 18, 24 and 36 months; the study design could not establish causation, only correlation]. The results of their study were published as a case-control study. Hooker used the same dataset to create a cohort study and found that there was no increased risk of autism in any of the groups (i.e., MMR does not cause autism) except one: African American males, for which he puportedly found a 3.36-fold increased risk of autism when they were vaccinated between 24 and 31 months. Read the two posts by those epidemiologists for why his analysis is suspect.
I'm not going to go into the science behind the studies, because it relies very heavily on statistics, and I'm not a statistician or epidemiologist. As an aside, neither is Dr. Hooker. Instead, I want to focus on some statements made by one Andrew Wakefield, the British doctor who committed scientific fraud, resulting in the full retraction of his 1998 case series study on MMR and the stripping of his medical license. Wakefield boldly added himself to the list of not only torturing science, but now adds to his accomplishments torturing history and ethics (granted, we already knew he was ethically challenged). You see, in his videos (
here and
here) about the alleged "whistleblower", William Thompson,Wakefield compared the purported "cover-up" to the Tuskegee syphilis debacle. It's a false comparison used simply to inflame people and claim the race card.
