CDC: Vaccine Study Design “Uninformative and Potentially Misleading”

CDC Director Dr. Julie Gerberding has delivered a potentially explosive report to the powerful House Appropriations Committee, in which she admits to a startling string of errors in the design and methods used in the CDC’s landmark 2003 study that found no link between mercury in vaccines and autism, ADHD, speech delay or tics.

Gerberding was responding to a 2006 report from the National Institute of Environmental Health Sciences (NIEHS), which concluded that the CDC’s flagship thimerosal safety study was riddled with “several areas of weaknesses” that combined to “reduce the usefulness” of the study.

“CDC concurs,” Dr. Gerberding wrote in an undated mea culpa to Congress, (provided to me through a Capital Hill staffer) adding that her agency “does not plan to use” the database in question, the Vaccine Safety Datalink, (VSD) for any future “ecological studies” of autism.

In fact, Gerberding’s report said, any continued use of the VSD for similar ecological studies of vaccines and autism “would be uninformative and potentially misleading.”

Ecological vaccine studies are large, epidemiological analyses of risks and trends using computerized data from large populations — in this case children enrolled at several big HMOs — without ever examining a single patient in person.

There is nothing about this on their site. Fantastic Government we have, is it not?!
