CDC report insists there’s NO LINK between thimerosal in vaccines and autism

06/26/2025 / By Ramon Tomey

Ahead of a vaccine advisory meeting, the CDC released a report denying any credible link between thimerosal (a mercury-based preservative) and autism, despite mercury’s known neurotoxicity.
Thimerosal was removed from most U.S. childhood vaccines in the early 2000s but remains in about four percent of flu shots (multidose vials) and is widely used globally due to cost-effectiveness.
Vaccine safety advocate Lyn Redwood (Children’s Health Defense) prepared to present evidence linking thimerosal to neurodevelopmental disorders at the CDC’s ACIP meeting (June 25–26), amid scrutiny over her inclusion.
Redwood’s presentation follows Health Secretary RFK Jr.’s overhaul of ACIP, with new members (e.g., Dr. Martin Kulldorff) who have questioned mainstream vaccine guidance, raising concerns among public health experts.
Redwood and others (e.g., Tracy Slepcevic, Jenny McCarthy) cite personal cases of vaccine-induced harm, contradicting CDC assurances. Critics like Dorit Reiss accuse Redwood of bias, while pediatricians defend thimerosal as “safe.”

Ahead of a key meeting of the Centers for Disease Control and Prevention‘s (CDC) vaccine advisory panel, a report from the public health agency claimed that there is no link between thimerosal in vaccines and autism.

The CDC released an updated report Tuesday, June 24, about the issue. The report insisted that there is no credible evidence supporting a connection between the mercury-based preservative thimerosal and autism. It cited scientific literature to back up the false claim of thimerosal’s safety – despite the fact that mercury is a known neurotoxin.

Thimerosal, a preservative historically used in multidose vaccine vials to prevent bacterial contamination, was supposedly removed from most childhood vaccines in the U.S. since the early 2000s. But it remains in about four percent of flu shots – primarily in multidose formulations. Globally, thimerosal is still widely used due to its cost-effectiveness.

The release of the CDC report came just days before a scheduled presentation by vaccine safety advocate Lyn Redwood. The president emerita of the health freedom group Children’s Health Defense (CHD) is set to present findings linking thimerosal to neurodevelopmental disorders at the CDC’s Advisory Committee on Immunization Practices (ACIP) meeting on June 25 and 26.

Her appearance before ACIP has raised alarms among public health experts, particularly given Health Secretary Robert F. Kennedy Jr.’s recent overhaul of the panel. Several new members like Dr. Martin Kulldorff – co-author of the Great Barrington Declaration opposing Wuhan coronavirus (COVID-19) lockdowns – have previously questioned mainstream vaccine guidance.

The fight against thimerosal in vaccines

A nurse practitioner by profession, Redwood is among the so-called “mercury moms” who pushed for Kennedy to get involved with defending children from this neurotoxin in vaccines. In early June, she also spoke about thimerosal during CHD’s “The Autism Cover-Up – Simpsonwood Scandal: 25 Years of Fraud & Corruption” event.

During the 2024-2025 flu season, the CDC claimed 96 percent of U.S. influenza vaccines were thimerosal-free. Pediatrician Dr. Sean O’Leary, a liaison to ACIP for the American Academy of Pediatrics, blindly defended the mercury-based vaccine ingredient. “Thimerosal has been demonstrated to be safe,” he remarked.

Meanwhile, UC Law San Francisco legal scholar Dorit Reiss criticized the ACIP’s inclusion of Redwood. “She has a clear history of bias and likely conflicts of interest,” Reiss said of the vaccine safety advocate.

Despite the smears by the mainstream medical establishment, Redwood and her allies have actual experiences to back up their claims. In 1999, she asserted that her son’s autism resulted from mercury exposure via vaccines. Others like “Warrior Mom” Tracy Slepcevic and actress and model Jenny McCarthy also attest to how the vaccines negatively harmed their children.
