CHD Scientist: CDC, FDA COVID Vaccine Safety Monitoring ‘Insulting, and Many People Are Injured’

By Suzanne Burdick, Ph.D. | The Defender | April 29, 2026

Federal health officials under the Biden administration failed abysmally to look for COVID-19 vaccine safety signals, according to congressional testimony delivered today by Children’s Health Defense (CHD) Senior Research Scientist Karl Jablonowski.

The government’s vaccine safety monitoring “over the past several years has been insulting, and many people are injured,” Jablonowski wrote in his written testimony.

History repeats itself if we don’t learn our lessons, Jablonowski warned.

“The COVID-19 pandemic created over 100 billionaires in the United States and over 1,000 billionaires around the world,” Jablonowski wrote. “Anything that profitable is going to repeat.”

Jablonowski, who holds a doctorate in biomedical and health informatics from the University of Washington’s School of Medicine, spoke as a witness at the U.S. Senate Permanent Subcommittee on Investigations hearing, “Unmasked: How Biden Health Officials Purposely Turned a Blind Eye Toward COVID-19 Vaccine Safety Signals.”

Hours before the hearing, Sen. Ron Johnson (R-Wis.), subcommittee chair, released a report detailing how Biden-era federal health officials refused to use a state-of-the-art statistical tool for detecting COVID-19 vaccination signals in VAERS — even though they knew the tool they were using was too broken to pick up on safety signals, including sudden cardiac death.

Johnson’s report, which cited roughly 600 pages of emails, revealed that in 2021, officials with the U.S. Food and Drug Administration (FDA) told an FDA researcher to “cease and desist” using the state-of-the-art tool to analyze COVID-19 vaccine injury reports in the Vaccine Adverse Event Reporting System (VAERS).

Johnson obtained the emails after he subpoenaed the U.S. Department of Health and Human Services in January 2025 for COVID-19 vaccine safety records and pandemic-related communications.

FDA was ‘blind’ to COVID vaccine injury reports in VAERS

In his testimony, Jablonowski detailed how each of the federal government’s three vaccine safety monitoring systems — VAERS, V-safe and Vaccine Safety Datalink (VSD) — had “pitfalls” and “failed” to adequately assess safety issues with the COVID-19 vaccine and other vaccines.

The failures of vaccine safety monitoring “can be, and were, catastrophic,” he said.

For instance, the FDA insisted on monitoring COVID-19 vaccine reports using a method that it knew didn’t work. The FDA knew the method was likely to give inaccurate results if similar vaccines — such as the Pfizer and Moderna COVID-19 vaccines — were included in the dataset. This is called masking.

“The FDA was completely blind to COVID-19 vaccine adverse events,” Jablonowski wrote. He said the FDA could have used an improved statistical method accounting for masking.

A 2022 peer-reviewed paper in Drug Safety showed that the improved method detected roughly 25 statistically significant COVID-19 vaccine safety signals — including sudden cardiac death, Bell’s palsy and pulmonary infarction — that the FDA’s older method missed.

In an earlier interview with The Defender, Jablonowski explained why it was so harmful for the FDA to continue using the older method:

“Imagine a night watchman has to find something on the ground. But instead of holding a flashlight, he is wearing sunglasses. In the morning, he says he didn’t find anything. That’s true, but it’s because he was using a tool that impeded his ability to see.”

As of March 27, 1,675,590 adverse events were reported to VAERS following COVID-19 vaccination, according to OpenVAERS. That number includes over 39,077 reports of death, 29,200 reports of myocarditis or pericarditis, and 18,009 reports of Bell’s palsy.

A national survey conducted in November 2025 found that roughly 1 in 10 U.S. adults who received the COVID-19 vaccine experienced “major” side effects.

V-safe was designed to collect ‘inconsequential’ data

Jablonowski told lawmakers that the Centers for Disease Control and Prevention’s (CDC) COVID-19 vaccine safety monitoring tool, V-safe, was designed to collect only “inconsequential” information that no one really cares about.

The V-safe app invited COVID-19 vaccine recipients to check off boxes to indicate what, if any, side effects they experienced after getting the shot.

However, the box options were for common short-term vaccine side effects that most people would consider “inconsequential,” such as chills, headache, joint pain, muscle or body aches, fatigue or tiredness, nausea, vomiting, diarrhea, abdominal pain or rash.

If a person experienced a more serious problem, they had to manually type it into the “other” text field, Jablonowski noted. He said:

“It is with horror that we find 366 individuals typed ‘myocarditis’ in the ‘other’ free-text field, a condition requiring a medical diagnosis. The horror is amplified by the nearly 50,000 registrants who typed ‘chest pain’ into the ‘other’ free-text field.”

Vaccine Safety Datalink is off-limits to independent researchers

Jablonowski also detailed how VSD, a collaborative database of patient information from 13 integrated healthcare organizations covering over 15.5 million people, also fails the public.

VSD data can ostensibly be used to detect vaccine safety issues in near-real time, Jablonowski said.

The problem is that only a small handful of scientists are ever allowed to look at the data. Jablonowski said:

“This many million-dollar taxpayer funded resource is not available to any scientist outside of the 13 Managed Care Organizations (MCO) or the federal government without independent IRB [independent review board] applications approved by all 13 MCOs, an estimated $250,000 per project.”

In other words, independent researchers are realistically barred from analyzing the data. “Transparency is simply unattainable,” Jablonowski said.
