Were either Dr. Thompson or Rep Posey on Oprah as "celebrity doctors"? I'm not sure how that is relevant to the topic of the thread otherwise. It really seems like you are here to troll as an "anti-vaxxer" rather than to discuss Oprah's Celebrity Doctors.
Also, Snopes has already blown this whole story apart last year...
What got lost in the brouhaha over Dr. Thompson's "confession," allegations about a "cover-up" at the CDC, and threats of whistleblower lawsuits was what should have been the main point: Did collected data actually prove that the MMR vaccine produces a 340% increased risk of autism in African-American boys? The answer is no, it did not.
On 27 August 2014, Dr. Hooker's article published in the journal Translational Neurodegeneration that concluded "African American males receiving the MMR vaccine prior to 24 months of age or 36 months of age are more likely to receive an autism diagnosis" was removed from public domain due to issues of conflict of interest and the questionable validity of its methods:
The Editor and Publisher regretfully retract the article as there were undeclared competing interests on the part of the author which compromised the peer review process. Furthermore, post-publication peer review raised concerns about the validity of the methods and statistical analysis, therefore the Editors no longer have confidence in the soundness of the findings.
The CDC issued a statement regarding the data in question, with instructions for accessing the study at the center of the controversy. As the CDC noted, the authors of that study suggested that the most likely explanation for the moderate correlation between autism and vaccination in young children was the existence of immunization requirements for autistic children enrolled in special education preschool programs:
Access to the information on the birth certificates allowed researchers to assess more complete information on race as well as other important characteristics, including possible risk factors for autism such as the child’s birth weight, mother’s age, and education. This information was not available for the children without birth certificates; hence CDC study did not present data by race on black, white, or other race children from the whole study sample. It presented the results on black and white/other race children from the group with birth certificates.
The study looked at different age groups: children vaccinated by 18 months, 24 months, and 36 months. The findings revealed that vaccination between 24 and 36 months was slightly more common among children with autism, and that association was strongest among children 3-5 years of age. The authors reported this finding was most likely a result of immunization requirements for preschool special education program attendance in children with autism.
For a thorough analysis of the flaws and misinformation associated with the current CDC autism "cover-up" conspiracy theory, we recommend the posts on the subject at ScienceBlogs, which note of the claim at the heart of this matter (i.e, allegedly suppressed proof of a 340% increased risk of autism in African-American boys after MMR vaccination) that:
Vaccination data were abstracted from immunization forms required for school entry, and records of children who were born in Georgia were linked to Georgia birth certificates for information on maternal and birth factors. Basically, no significant associations were found between the age cutoffs examined and the risk of autism. I note that, even in the "reanalysis" by Brian Hooker, there still isn't any such correlation for children who are not African American boys
So is Hooker’s result valid? Was there really a 3.36-fold increased risk for autism in African-American males who received MMR vaccination before the age of 36 months in this dataset? Hooker [performed] multiple subset analyses, which, of course, are prone to false positives. As we say, if you slice and dice the evidence more and more finely, eventually you will find apparent correlations that might or might not be real. In this case, I doubt Hooker's correlation is real.
There's no biologically plausible reason why there would be an effect observed in African-Americans but no other race and, more specifically than that, in African-American males. In the discussion, Hooker does a bunch of handwaving about lower vitamin D levels and the like in African American boys, but there really isn't a biologically plausible mechanism to account for his observation, suggesting that it's probably spurious. There are multiple other studies, many much larger than this one, that failed to find a correlation between MMR and autism.
What [Hooker] has done, apparently, is found grist for a perfect conspiracy theory to demonize the CDC, play the race card in a truly despicable fashion, and cast fear, uncertainty, and doubt about the CDC vaccination program, knowing that most of the white antivaccine activists who support [him] hate the CDC so much that they won't notice that even Hooker's reanalysis doesn’t support their belief that vaccines caused the autism in their children.
