Robert F. Kennedy Jr. and the Simpsonwood Vaccine Controversy
In June 2005, a high-profile article titled "Deadly Immunity," written by Robert F. Kennedy, Jr., sparked significant debate regarding vaccine safety. Published in Rolling Stone and on Salon.com, the piece focused on the Simpsonwood conference, alleging a conspiracy between private industry and government agencies to hide critical safety data from the public.
The Allegations of "Deadly Immunity"
Kennedy claimed that government officials and private entities colluded to thwart the Freedom of Information Act (a law allowing citizens to request access to government records) to withhold findings related to vaccine safety. Specifically, he alleged that data from the Simpsonwood conference linked thimerosal—a mercury-based preservative used in some vaccines—to an increase in autism cases.
Kennedy further asserted that the lead researcher involved in the study had "reworked" the data to deliberately bury the connection between thimerosal and autism.
[ไม่มีภาพประกอบ]Scientific Errors and Retractions
Despite the initial impact of the article, it was later found to contain numerous factual and scientific inaccuracies. These errors included overstating the amount of ethylmercury (the specific form of mercury found in thimerosal) present in vaccines and falsely claiming that the rotavirus vaccine contained thimerosal. Additionally, Kennedy wrongly claimed that a researcher held a patent on one of the vaccines under discussion.
Salon.com acknowledged that these errors undermined the exposé and issued five separate corrections. By January 2011, the publisher fully retracted the article, citing flaws in the science connecting vaccines to autism and the weight of the criticisms against the piece.
The Role of Thomas Verstraeten and the CDC
A central figure in the controversy was Thomas Verstraeten, the lead researcher. Kennedy pointed out that by the time the Simpsonwood study results were published in 2003, Verstraeten had transitioned to a role at GlaxoSmithKline. Kennedy argued that the delay in publication provided an opportunity to manipulate the data to align with the Centers for Disease Control and Prevention's (CDC) alleged goal of obscuring the link to autism.
Verstraeten denied these allegations and published his own account of the events in the medical journal Pediatrics.
Official Findings and Conclusions
The controversy reached the U.S. Senate Committee on Health, Education, Labor and Pensions in September 2007. After reviewing the claims, the Committee rejected the allegations of impropriety against both Verstraeten and the CDC.
The Committee concluded that the CDC did not hide the Simpsonwood data; instead, it distributed the information to outside parties for interpretation and made the transcripts of those discussions available to the general public.

Frequently Asked Questions
What was the main claim of the "Deadly Immunity" article?
The article claimed that the government and private industry conspired to hide data from the Simpsonwood conference that linked the vaccine preservative thimerosal to autism.
Why was the article eventually retracted?
Salon.com retracted the piece in 2011 because of numerous scientific flaws and factual errors that undermined the value of the exposé.
Did the rotavirus vaccine contain thimerosal?
No. The claim that the rotavirus vaccine contained thimerosal was one of the specific errors identified in Kennedy's article.
What did the U.S. Senate Committee conclude about the CDC?
The Committee found that the CDC did not restrict access to the Simpsonwood data but instead shared it with outside experts and made discussion transcripts public.
Who is Thomas Verstraeten?
He was the lead researcher for the study discussed at the Simpsonwood conference and was falsely accused by Kennedy of manipulating data to hide a link between vaccines and autism.
