Federal guidelines no longer recommend flu vaccines containing a preservative, used in a small percentage of vaccines, that has been falsely linked to autism.

The CDC says there is no evidence of harm from mercury-based thimerosal.

The United States will stop distributing all influenza vaccines that contain mercury-based preservative thimerosal, marking the latest move by U.S. Health Secretary Robert F. Kennedy Jr. to reshape vaccine policy.

A CDC panel’s vote to stop recommending thimerosal-containing flu shots would have limited impact, but it illustrates how the anti-vaccine movement is achieving its goals.
