‘Regulators were WELL AWARE…’: Whistleblower 'exposes' FDA, CDC over COVID-19 vaccine injuries

Key Concepts

• Pharmacovigilance: The science and activities relating to the detection, assessment, understanding, and prevention of adverse effects or any other vaccine/medicine-related problem.
• Masking: A statistical phenomenon where the signal for one vaccine is obscured because the comparison baseline is artificially inflated by reports from other vaccines.
• VAERS (Vaccine Adverse Event Reporting System): A passive surveillance system used by the CDC and FDA to detect potential safety issues.
• Empirical Bayesian (EB) Method: A statistical data-mining technique used to identify safety signals in large databases.
• PRR (Proportional Reporting Ratio): A method used to compare the frequency of an adverse event for a specific vaccine against other vaccines in the database.
• V-safe: An active surveillance system using text messaging to collect health check-ins from vaccine recipients.
• VSD (Vaccine Safety Datalink): A collaborative project between the CDC and healthcare organizations that uses electronic health records for active safety monitoring.

1. The Problem of Statistical Masking

Dr. David Wiseman highlighted a critical failure in the FDA’s safety monitoring during the COVID-19 vaccine rollout.

• The Mechanism: Masking occurs when the statistical signal of a specific vaccine (e.g., Moderna’s myocarditis signal) is "drowned out" because the baseline comparison includes data from other vaccines (e.g., Pfizer’s myocarditis reports).
• Regulatory Failure: Despite being warned by veteran FDA statistician Dr. Anna Scharfman—who collaborated with the inventor of the Empirica Signal software, Dr. William Du Mouchel—the FDA failed to implement improved procedures to "unmask" these signals.
• Evidence: Dr. Scharfman and Dr. Du Mouchel published findings in the journal Drug Safety (2022) demonstrating that their improved methods could unmask hundreds of statistical signals that the FDA’s standard analysis missed.
• Consequences: The FDA’s failure to correct for masking meant the U.S. lacked a functional early warning system during the deployment of mRNA vaccines.

2. Limitations of Surveillance Systems

Dr. Karl Jablonowski provided a critique of the three primary pillars of U.S. vaccine safety monitoring:

• VAERS: Suffered from "gross underreporting" historically, but the massive influx of COVID-19 reports created a "disproportionality" that rendered the FDA’s Bayesian analysis ineffective.
• V-safe: Criticized for collecting "inconsequential data." Dr. Jablonowski noted that the system failed to include myocarditis in its check-in prompts, despite 366 individuals manually typing "myocarditis" and nearly 50,000 typing "chest pain" into free-text fields.
• VSD: While capable of rapid cycle analysis, it often misses delayed-onset events and rarely utilizes more robust methodologies like "vaccinated vs. unvaccinated" comparisons.

3. Regulatory and Methodological Failures

• Standard Operating Procedures (SOPs): The CDC reportedly abandoned its responsibility to generate PRR analyses, relying instead on the FDA’s Bayesian work, which was itself compromised by masking.
• Trivialization of Signals: Witnesses argued that officials avoided using the term "safety signal" to minimize the perceived risk, which hindered investigations into potential adverse events.
• Hastened Approval: Dr. Wiseman noted that the full approval of Comirnaty occurred while internal concerns regarding masking were being actively voiced by staff.

4. Notable Quotes

• Dr. David Wiseman: "In a simple analogy, hemlock and arsenic appear equally toxic when compared separately with a non-toxic baseline control such as tea. However, if hemlock's baseline data include arsenic data, hemlock's signal is drowned out or masked, appearing innocuous."
• Dr. Karl Jablonowski: "Had they actually turned out to be safe, it would have been serendipitous, a happy accident. Luck is not a pillar of public health."
• Dr. Karl Jablonowski: "Simply put, during the largest pharmaceutical rollout in human history, pharmacovigilance did not exist. That is the betrayal of our time."

5. Synthesis and Conclusion

The testimony presents a narrative of systemic failure in U.S. vaccine safety monitoring. The core argument is that regulators possessed the software and the expertise to detect safety signals (via the EB method and unmasking techniques) but failed to implement them. This resulted in a "blind spot" where the sheer volume of data from the COVID-19 vaccine rollout masked serious adverse events. The witnesses conclude that the lack of rigorous, transparent pharmacovigilance—compounded by the marginalization of internal whistleblowers—has severely compromised public trust and the integrity of the nation's vaccine safety infrastructure.
