FDA Silenced Scientists Who Flagged Vaccine Safety Risks
Internal documents reveal the FDA suppressed scientists who identified flaws in its vaccine safety monitoring system, withholding critical health data from the public while downgrading pediatric death classifications.
The Food and Drug Administration knew its vaccine safety monitoring system was failing. Rather than fix the flawed algorithm, the agency silenced the scientists who exposed the problem and withheld safety data from the American public. Senator Ron Johnson calls the deliberate suppression of critical health information "the biggest government scandal of my lifetime." The pattern shows federal regulators placing institutional interests above public health.
Internal documents expose a fundamental flaw in the FDA's surveillance system. The agency's method suffered from a phenomenon called "masking" that concealed dangerous adverse events. Agency scientists Dr. Ana Szarfman and Dr. William DuMouchel developed a superior statistical approach. Their method identified 49 examples of extreme masking and 25 previously undetected safety signals. The analysis uncovered risks including sudden cardiac death, Bell's palsy, and pulmonary infarction that the standard system missed.
FDA officials ordered Szarfman to halt her work. Dr. Peter Marks, then director of the FDA's Center for Biologics Evaluation and Research, wrote in a September 2021 email that Szarfman "has been asked to cease and desist, because the strategy that she is using could create erroneous conflicts that feed in to anti-vaccination rhetoric." Marks dismissed her reports as a "major distraction."
The agency also restricted data access to shield itself from public scrutiny. In September 2022, the FDA halted weekly data-mining reports to the Centers for Disease Control and Prevention. A CDC official later wrote in November 2022 that "because of the FOIAs … we may have asked FDA to stop sending these weekly data mining outputs." The timing aligned with Freedom of Information Act requests from Senator Johnson and organizations including Children's Health Defense and ICAN.
Pressure mounted on FDA scientists to downgrade pediatric death classifications. Career scientists initially identified 10 children's deaths as "probably" or "possibly" vaccine-related in November 2025, according to an internal memo from then-CBER Director Dr. Vinay Prasad. "At least 10 children have died after and because of receiving COVID-19 vaccination," Prasad wrote. "The real number is higher."
Within days, the agency downgraded three of those deaths to "un-assessable" or "unlikely." The final December 5, 2025 review classified zero deaths as "certain," two as "probable," and five as "possible" among 96 pediatric cases examined. Yale pathologist Dr. James Gill criticized the FDA's use of parvovirus findings to justify the downgrades. He called the approach a "red herring."
"The legacy media is ignoring the biggest government scandal of my lifetime," Johnson stated on his Senate website June 12. "The FDA knew that its system failed to flag safety signals from the COVID injection. Rather than disclose that information, agency officials chose to hide it and lie to the public."
The Wisconsin Republican states that major media outlets including the Wall Street Journal, New York Times, Washington Post, and CNN declined to report on documented evidence of regulatory failure. He questions whether pharmaceutical advertising spending influenced editorial decisions about covering the vaccine safety scandal.
FDA leadership changes raise questions about accountability. Commissioner Marty Makary resigned May 12 under pressure. CBER Director Prasad left April 30. CDER Director Tracy Beth Høeg departed mid-May. The agency's Division of Pharmacovigilance recommended a Boxed Warning for "myocarditis with fatal outcomes" in mRNA COVID vaccine labels. The labeling change never materialized.
Cumulative worldwide VAERS data shows 1,676,100 adverse events and 39,099 deaths associated with COVID-19 injections. Nearly one-quarter of those fatalities occurred within two days of vaccination. Johnson questioned the CDC's recent $1.24 billion purchase of Pfizer vaccines in a June 16 letter. He noted the transaction occurred despite safety concerns uncovered by his subcommittee.
Behind every statistic is a family that never received answers. The FDA's actions reveal a systemic failure that compromised public safety. Agency officials received warnings about flawed surveillance methods. They suppressed internal scientists who identified superior alternatives. They restricted data transparency and downgraded concerning findings. All this occurred while the agency maintained public confidence in vaccine safety.
