FDA Officials Silenced Safety Data on COVID Vaccines
Newly released documents reveal federal health agencies concealed known COVID-19 vaccine safety risks during the pandemic rollout, silencing scientists and denying Americans their fundamental right to informed consent.
Americans lost their right to informed consent when federal health agencies concealed known safety risks of COVID-19 vaccines. Newly released documents show the Food and Drug Administration detected serious safety signals within months of the rollout. Rather than warn the public, officials silenced career scientists and buried the data to protect institutional narratives.
"This is a huge scandal," Senator Ron Johnson told The Daily Wire. "For a number of months they were talking about these things. At some point they asked: is there a safety signal? And the answer was yes. And yet a couple of days later, they decided not to issue a warning." Johnson leads the Senate Permanent Subcommittee on Investigations, which obtained the revelations.
The subcommittee released 600 pages of internal emails on April 29. The correspondence details a coordinated effort to suppress medical data and prioritize bureaucratic messaging over public health. By burying these findings, Washington denied millions of Americans the chance to make informed choices about their own bodies.
In late February 2021, FDA expert Dr. Ana Szarfman identified dozens of safety signals using an improved data analysis method. She immediately shared her findings with vaccine surveillance leaders, including Dr. Peter Marks, who headed the Center for Biologics Evaluation and Research. Instead of addressing the urgent warnings, Marks ordered Szarfman to "hold off on creating and sending data mining reports and analyses."
Marks argued that Szarfman's work could "create erroneous conflicts that feed into anti-vaccination rhetoric." Agency leadership ultimately told her to "cease and desist" from tracking statistically significant adverse events. The suppressed data flagged risks including acute myocardial infarction, embolism, thrombosis, and sudden death.
While FDA leadership stifled internal warnings, the Biden administration coordinated across agencies to downplay the emerging crisis. FDA Commissioner Janet Woodcock wrote to CDC Director Rochelle Walensky on May 26, 2021, opposing "blasting out the warning as drafted." The day before, CDC official Sara Oliver emailed Moderna to avoid appearing "alarmist" with any formal Health Alert Network notification.
The White House simultaneously distributed talking points to senior officials like Anthony Fauci, instructing them to describe myocarditis as "rare" rather than urgent. This coordinated suppression unfolded while the Vaccine Adverse Event Reporting System already logged 752 myocarditis cases by late May 2021.
Physicians who attempted to warn the public faced immediate censorship and professional retaliation. Twitter labeled Dr. Tracy Beth Hoeg's tweet about vaccine-related myocarditis as "misleading," mirroring a broader censorship pattern documented by congressional investigators. In September 2022, the platform suspended Philadelphia cardiologist Dr. Anish Koka for linking to a review of post-vaccine heart inflammation.
"Yesterday's sworn congressional testimony detailed remarkable evidence that a multitude of taxpayer-funded FDA officials used their positions of public trust to silence career FDA scientists by obscuring very serious drug safety findings in order to protect commercial Pharma narratives," said Dr. David Gortler. The former FDA senior official and Yale professor of pharmacology highlighted the betrayal of public health ethics.
The delayed response carried catastrophic consequences for patients. By the time the FDA updated vaccine labels on June 25, 2021, thousands of Americans had already received injections without knowing the documented risks. As of April 2025, VAERS reported 38,607 deaths and 1.6 million adverse events worldwide linked to the shots.
The Senate report reveals regulators systematically suppressed a more sensitive data analysis method designed to detect "extreme masking." This statistical phenomenon occurs when signals for one vaccine become obscured by reports tied to other vaccines. Dr. David Wiseman, president of Synechion, Inc., testified that officials identified 49 examples of masking that hid approximately 25 previously undetected safety signals.
"Our knowledge of the safety of the mRNA vaccine prior to the issuance of the Emergency Use Authorization was poor," stated Dr. Karl Jablonowski, a senior research scientist with Children's Health Defense. "Pharmacovigilance behind-closed-doors should give everyone pause. It is simply too important to not do it correctly and timely. Lapses can be, and were, catastrophic."
The government's suppression apparatus extended well beyond internal FDA memos to include coordinated censorship with major social media platforms. Congressional investigations documented how CDC officials partnered with Twitter to flag and remove content discussing vaccine safety concerns. This enforcement mechanism effectively silenced dissenting medical professionals.
Senator Johnson's investigation marks the second major report on the cover-up. It follows a 54-page Senate document released in May 2025, backed by more than 2,400 pages of FOIA records.
That interim report established federal health agencies knew as early as February 2021 that mRNA vaccines carried cardiac risks for young men. Israeli health officials had already alerted Washington to 40 cases and a probable causal link that same month.
A Defense Department contractor presented findings to a vaccine safety working group in mid-April 2021. The analysis concluded there was a high likelihood the cardiac symptoms represented hypersensitivity eosinophilic myocarditis.
The systemic failure demonstrates how big government prioritized institutional narratives over individual rights and medical ethics. Washington violated the core principle of informed consent while leveraging corporate partners to enforce compliance.
"Rather than provide informed consent, the federal health agencies, the Biden administration, covered it up," Johnson stated. "They downplayed the signals." The Senate report now demands that the "full extent" of the administration's "failure to immediately warn the public about all COVID-19 vaccine adverse events must be completely exposed."
