Fact Check: "CDC scientists censored safety data on thimerosal before the meeting."
What We Know
The claim that "CDC scientists censored safety data on thimerosal before the meeting" stems from recent events involving the Advisory Committee on Immunization Practices (ACIP) and its discussions regarding thimerosal, a mercury-based preservative used in some vaccines. According to reports, a scientific review of thimerosal's safety was posted online by CDC scientists but was subsequently taken down shortly thereafter (source-1). This review concluded that thimerosal is safe and not linked to conditions such as autism, a claim that has been widely supported by numerous studies over the years (source-2).
The recent ACIP meeting, which included new members appointed by Health Secretary Robert F. Kennedy Jr., saw discussions that raised concerns about thimerosal, despite the existing scientific consensus. One of the panelists, Lyn Redwood, presented claims about thimerosal's dangers, which were criticized for being misleading and lacking scientific backing (source-1; source-4).
Analysis
The assertion of censorship is complex. While it is true that a safety review was taken down, the context surrounding this action is crucial. The report was prepared in anticipation of the ACIP meeting, which has been criticized for allowing presentations from individuals with anti-vaccine sentiments, such as Redwood, who have been known to spread misinformation (source-2; source-8).
Critics of the meeting have pointed out that the inclusion of such presentations undermines the scientific integrity of the discussions. For instance, Dr. Cody Meissner, the only dissenting vote against the panel's decision, emphasized the lack of evidence supporting the claims made about thimerosal (source-2).
The reliability of sources discussing this issue varies. The New York Times and Washington Post are reputable outlets with a history of fact-checking and journalistic integrity, while the presentations made at the ACIP meeting were criticized for lacking scientific rigor (source-1; source-4).
Conclusion
The claim that "CDC scientists censored safety data on thimerosal before the meeting" is Partially True. While it is accurate that a safety review was removed from public access, the reasons behind this action and the context of the ACIP meeting reveal a more nuanced situation. The meeting's discussions included significant misinformation, and the actions taken by the CDC can be seen as an attempt to manage the integrity of the scientific discourse surrounding vaccine safety. However, the removal of the report raises legitimate concerns about transparency and the dissemination of scientific information.
