Calls for COVID-19 vaccine recall – FDA’s own study finds DNA contamination in Pfizer vaccines

“It is alarming that the public is made aware of this contamination in an obscure journal that features high school science research. One has to ask, ‘Where is the FDA now?’ and ‘Why hasn’t the public been alerted of this?’”
The peer-reviewed study in the Journal of High School Science was authored by three high school students and performed at an FDA lab under the supervision of FDA scientists. The findings prompted renewed calls for a moratorium on COVID-19 vaccines.
A peer-reviewed study performed at a U.S. Food and Drug Administration (FDA) laboratory by high school students has confirmed the presence of a high level of DNA contamination in Pfizer’s mRNA COVID-19 vaccine.
The study, published December 29, 2024, in the Journal of High School Science, was authored by three students at Centreville High School in Clifton, Virginia, and performed under the supervision of FDA scientists.
Maryanne Demasi, Ph.D., an investigative medical reporter, was the first to report on the study.

The research, performed at the FDA’s White Oak Campus in Maryland, found that levels of residual DNA in the Pfizer COVID-19 vaccine were 6 to 470 times higher than regulatory safety limits. The students tested two lots of the vaccine, finding they contained “residual DNA to a level that exceeds 10 ng [nanograms] per dose.”
“The potential health risk posed by residual small DNA fragments is currently unknown,” the study stated. However, the authors also said that DNA contamination may result in insertional mutagenesis – or DNA mutations – that can cause cancer.
Speaking last month on “The Defender In-Depth,” Kevin McKernan, who first identified DNA contamination in the shots in 2023, said DNA in vaccines can pose health risks because the DNA “could integrate into the genome and cause disruption of the genome … or it could disrupt other genes that are related to cancer.”
The FDA did not respond to multiple requests for comment on the study.
COVID vaccines ‘must be immediately recalled’
The new findings challenge “years of dismissals by regulatory authorities, who had previously labelled concerns about excessive DNA contamination as baseless,” Demasi wrote on Substack.
The findings also align with earlier reports from independent laboratories in the U.S., Canada, Australia, Germany, and France, she said.
McKernan, founder of Medicinal Genomics, told The Defender that eight studies have found DNA over the limit. “Very few studies are surveying a large number of lots, so each study is additive,” he said.
Epidemiologist Nicolas Hulscher said that in “light of this evidence, the COVID-19 genetic injections must be immediately recalled, to protect the public from further harm.”
Nikolai Petrovsky, Ph.D., director of biotechnology company Vaxine Pty Ltd., told Demasi that the findings are a “smoking gun” and that the new study “clearly shows the FDA was aware of these data.”
Christof Plothe, D.O., a member of the World Council for Health steering committee, agreed. He said:
So far, the European, Australian, and American health regulatory boards have denied any risks from plasmid DNA contamination in the COVID-19 injections despite nine studies by internationally known research teams.
All teams concluded that this contamination poses an unacceptable risk to three-quarters of the world’s population.… Three teams so far have demonstrated the integration into human cells. To what extent this is happening to everybody who was injected needs to be investigated.

McKernan said that the FDA has long ignored evidence of the dangers posed by mRNA COVID-19 vaccines.
“The criteria for pulling these shots was established long before DNA contamination was first discovered,” he said. “I would hope that evidence of highly variable manufacturing would be grounds for immediate class 1 recall from the FDA. They are currently distracted with performing class 1 recalls on non-lethal hairspray.”
A Class 1 recall involves “a situation in which there is a reasonable probability that the use of, or exposure to, a violative product will cause serious adverse health consequences or death.”
According to Demasi, “The FDA is expected to comment on the findings this week. However, the agency has yet to issue a public alert, recall the affected batches, or explain how vials exceeding safety standards were allowed to reach the market.”
Plothe noted that Demasi presented evidence of DNA contamination to the FDA in September 2024, asking if the agency had launched an investigation or requested further testing of the mRNA vaccines by their manufacturers.
“Nothing resulted from this request,” Plothe said. “As nine studies have proven this severe contamination and repeated requests to health regulatory boards have not led to any consequence, we must ask about the motive.”
Brian Hooker, Ph.D., chief scientific officer for Children’s Health Defense (CHD), noted the irony of high school students discovering what the FDA has seemingly missed in the four-plus years since the vaccines’ introduction.
“It is ironic that it takes student researchers at the FDA to do the work of the FDA regulators,” Hooker said. “It is alarming that the public is made aware of this contamination in an obscure journal that features high school science research. One has to ask, ‘Where is the FDA now?’ and ‘Why hasn’t the public been alerted of this?’”
Demasi said that the significance of the new study’s findings is that they came from research performed at an FDA facility.
“Now that DNA contamination of the mRNA vaccines has been verified in the laboratory of an official agency and published in a peer-reviewed journal, it becomes difficult to ignore,” Demasi wrote. “It also places vaccine manufacturers and regulators in a precarious position.”

From the Brownstone Institute
An explosive new study conducted within the US Food and Drug Administration’s (FDA) own laboratory has revealed excessively high levels of DNA contamination in Pfizer’s mRNA Covid-19 vaccine.
Tests conducted at the FDA’s White Oak Campus in Maryland found that residual DNA levels exceeded regulatory safety limits by 6 to 470 times.
The study was undertaken by student researchers under the supervision of FDA scientists. The vaccine vials were sourced from BEI Resources, a trusted supplier affiliated with the National Institute of Allergy and Infectious Diseases (NIAID), previously headed by Anthony Fauci.
Recently published in the Journal of High School Science, the peer-reviewed study challenges years of dismissals by regulatory authorities, who had previously labelled concerns about excessive DNA contamination as baseless.
The FDA is expected to comment on the findings this week. However, the agency has yet to issue a public alert, recall the affected batches, or explain how vials exceeding safety standards were allowed to reach the market.
The Methods
The student researchers employed two primary analytical methods:
- NanoDrop Analysis – This technique uses UV spectrometry to measure the combined levels of DNA and RNA in the vaccine. While it provides an initial assessment, it tends to overestimate DNA concentrations due to interference from RNA, even when RNA-removal kits are utilised.
- Qubit Analysis – For more precise measurements, the researchers relied on the Qubit system, which quantifies double-stranded DNA using fluorometric dye.
Both methods confirmed the presence of DNA contamination far above permissible thresholds. These findings align with earlier reports from independent laboratories in the United States, Canada, Australia, Germany, and France.
Expert Reaction
Kevin McKernan, a former director of the Human Genome Project, described the findings as a “bombshell,” criticizing the FDA for its lack of transparency.
“These findings are significant not just for what they reveal but for what they suggest has been concealed from public scrutiny. Why has the FDA kept these data under wraps?” McKernan questioned.
CSO and Founder of Medicinal Genomics
While commending the students’ work, he also noted limitations in the study’s methods, which may have underestimated contamination levels.
“The Qubit analysis can under-detect DNA by up to 70% when enzymes are used during sample preparation,” McKernan explained. “Additionally, the Plasmid Prep kit used in the study does not efficiently capture small DNA fragments, further contributing to underestimation.”
In addition to genome integration, McKernan highlighted another potential cancer-causing mechanism of DNA contamination in the vaccines.
He explained that plasmid DNA fragments entering the cell’s cytoplasm with the help of lipid nanoparticles could overstimulate the cGAS-STING pathway, a crucial component of the innate immune response.
“Chronic activation of the cGAS-STING pathway could paradoxically fuel cancer growth,” McKernan warned. “Repeated exposure to foreign DNA through COVID-19 boosters may amplify this risk over time, creating conditions conducive to cancer development.”
Adding to the controversy, traces of the SV40 promoter were detected among the DNA fragments. While the authors concluded that these fragments were “non-replication-competent” meaning they cannot replicate in humans, McKernan disagreed.
“To assert that the DNA fragments are non-functional, they would need to transfect mammalian cells and perform sequencing, which wasn’t done here,” McKernan stated.
“Moreover, the methods used in this study don’t effectively capture the full length of DNA fragments. A more rigorous sequencing analysis could reveal SV40 fragments several thousand base pairs long, which would likely be functional,” he added.
Regulatory Oversight under Scrutiny
Nikolai Petrovsky, a Professor of Immunology and director of Vaxine Pty Ltd, described the findings as a “smoking gun.”
“It clearly shows the FDA was aware of these data. Given that these studies were conducted in their own labs under the supervision of their own scientists, it would be hard to argue they were unaware,” he said.
Nikolai Petrovsky, Professor of Immunology and Infectious Disease at the Australian Respiratory and Sleep Medicine Institute in Adelaide
Prof Petrovsky praised the quality of work carried out by the students at the FDA labs.
“The irony is striking,” he remarked. “These students performed essential work that the regulators failed to do. It’s not overly complicated—we shouldn’t have had to rely on students to conduct tests that were the regulators’ responsibility in the first place.”
The Australian Therapeutic Goods Administration (TGA), which has consistently defended the safety of the mRNA vaccines, released its own batch testing results, claiming they met regulatory standards. However, Prof Petrovsky criticised the TGA’s testing methods.
“The TGA’s method was not fit for purpose,” he argued. “It didn’t assess all the DNA in the vials. It only looked for a small fragment, which would severely underestimate the total amount of DNA detected.”
Implications for Manufacturers and Regulators
Now that DNA contamination of the mRNA vaccines has been verified in the laboratory of an official agency and published in a peer-reviewed journal, it becomes difficult to ignore.
It also places vaccine manufacturers and regulators in a precarious position.
Addressing the contamination issue would likely require revising manufacturing processes to remove residual DNA, which Prof Petrovsky explained would be impractical.
“The only practical solution is for regulators to require manufacturers to demonstrate that the plasmid DNA levels in the vaccines are safe,” Prof Petrovsky stated.
“Otherwise, efforts to remove the residual DNA would result in an entirely new vaccine, requiring new trials and effectively restarting the process with an untested product.”
Now the onus is on regulators to provide clarity and take decisive action to restore confidence in their oversight. Anything less risks deepening the scepticism of the public.
Both the US and Australian drug regulators have been approached for comment.

Our immune systems are supposed to fight viruses. Now they invite them round for tea. It’s all down to IgG4…
Have you heard about the IgG4 antibody switch? It’s been glossed over in official discussions about Covid-19 ‘vaccines’, but it’s the elephant in the room. Let’s break it down and explore why this may matter more than we’re being told.
The antibody switch: what’s the big deal?
Our immune system is like a well-trained army, with different types of antibodies serving as its soldiers. Among them, IgG antibodies are the frontline warriors, designed to neutralize viruses and protect us from infections. But here’s the catch: not all IgG antibodies are created equal. Think of IgG4 antibodies as the peacekeepers of the immune system. They’re not fighters like the other IgG subclasses—they’re more about tolerance, calming things down. They’re certainly not about launching an attack.
Now, here’s where it gets interesting (and worrying).
Studies have shown that repeated Covid-19 mRNA injections—especially after the second dose or booster—cause the body to switch from producing the more effective IgG3 antibodies to producing IgG4. Essentially, the immune system is shifting toward tolerance rather than attack.
Sounds harmless, right? Well, not so fast. Here’s a look at what this shift might mean:
1. More Covid-19 infections
Imagine your immune system being rewired to tolerate the virus instead of fighting it. That’s essentially what the IgG4 switch could entail. A study from the Cleveland Clinic found a troubling trend: the more Covid-19 vaccine doses a person received, the higher their risk of getting infected. This isn’t what we were promised with “safe and effective,” is it? The IgG4 antibodies might be making the body less effective at dealing with the virus, leaving vaccinated individuals more susceptible to reinfections.

2. The potential for worse outcomes
IgG4 antibodies are great if you’re dealing with allergies, as they help the body tolerate allergens. But when it comes to fighting a virus like SARS-CoV-2, this tolerance could backfire. Instead of neutralizing the virus, the immune system might let it hang around longer, potentially leading to more severe disease outcomes. It’s like inviting a burglar into your house and offering them tea instead of calling the police.
3. The risk of other conditions
This shift to IgG4 isn’t just about Covid-19. It could open the door to other IgG4-related diseases (known as IgG4-RD). These are a group of conditions where the immune system starts attacking various organs, causing inflammation and fibrosis (thickening or scarring of tissues). Examples include autoimmune pancreatitis, kidney disease, and even conditions affecting the lungs or brain. There have been reports of individuals developing these conditions after receiving the mRNA vaccines. Coincidence? Maybe. But it’s enough to warrant serious investigation.
Below is a list of IgG4-related diseases (IgG4-RD) and other pathologies associated with elevated IgG4 levels that could also be related to IgG4 rising after mRNA injections:
- Type 1 Autoimmune Pancreatitis (AIP): Chronic inflammation of the pancreas, often presenting with abdominal pain, jaundice, or weight loss. It is one of the most common manifestations of IgG4-RD.
- Sialadenitis (Mikulicz’s Disease): Enlargement of the salivary and lacrimal glands, leading to dry mouth and eyes. This is a classic presentation of IgG4-RD in the head and neck region (Stone et al., 2012).
- Retroperitoneal Fibrosis: Thickening and fibrosis of the tissue behind the peritoneum, which can lead to ureteral obstruction and kidney damage (Stone et al., 2012).
- Riedel’s Thyroiditis: A rare form of thyroiditis involving fibrosis of the thyroid gland. It can present as a hard, fixed thyroid mass that mimics malignancy (Stone et al., 2012).
- Küttner’s Tumor (Chronic Sclerosing Sialadenitis): Affects the submandibular glands, causing enlargement and fibrosis, often mistaken for a tumor (Stone et al., 2012).
- IgG4-Related Sclerosing Cholangitis: Involves the bile ducts, often associated with autoimmune pancreatitis. Can lead to jaundice and bile duct obstruction (Stone et al., 2012).
- IgG4-Related Ophthalmic Disease: Involves orbital inflammation and can cause proptosis (bulging eyes), double vision, or orbital masses (Stone et al., 2012; Uchida et al., 2022).
- IgG4-Related Aortitis and Periaortitis: Inflammation of the aorta and surrounding tissues, which may lead to aneurysms or vascular complications (Stone et al., 2012).
- IgG4-Related Kidney Disease: Includes tubulointerstitial nephritis and other renal manifestations, leading to kidney dysfunction or masses (Stone et al., 2012; Uchida et al., 2022).
- IgG4-Related Lung Disease: Pulmonary involvement, presenting with inflammatory pseudotumors, interstitial pneumonia, or pleural thickening (Stone et al., 2012).
- IgG4-Related Lymphadenopathy: Enlargement of lymph nodes that may mimic lymphoma (Stone et al., 2012).
- IgG4-Related Skin Disease: While less common, presents as various cutaneous lesions, including plaques or nodules (Stone et al., 2012).
- IgG4-Related Prostatitis: Enlargement of the prostate, causing lower urinary tract symptoms (Stone et al., 2012).
- IgG4-Related Hypophysitis: Involves inflammation of the pituitary gland, leading to hormonal imbalances such as adrenal insufficiency or diabetes insipidus (Stone et al., 2012).
- IgG4-Related Pachymeningitis: Inflammation of the dura mater (the outer membrane covering the brain and spinal cord), leading to headaches, cranial nerve palsies, or other neurological symptoms (Stone et al., 2012).
That’s not all. There are potentially broader implications of elevated IgG4 levels that we must consider:
- Repeated infections. Elevated IgG4 levels may impair the immune system’s ability to clear infections, as IgG4 is less effective at neutralizing pathogens (Aalberse, 2009; Irrgang, 2021).
- Autoimmune diseases. Elevated IgG4 levels may contribute to autoimmune processes, where the immune system attacks its own tissues (Watad, 2021).
- Cancer risks. Chronic inflammation caused by IgG4-related conditions may increase the risk of certain malignancies. While not directly caused by IgG4, this link warrants further research (Uchida, 2022).
- Idiopathic Interstitial Lung Disease. Chronic inflammation and fibrosis in the lungs may lead to respiratory symptoms, further complicating the clinical picture (Stone, 2012).
- Systemic Vasculitis. Inflammation of blood vessels associated with IgG4-RD can cause systemic complications and end-organ damage (Stone, 2012).
Why isn’t this being talked about?
Good question. The IgG4 switch is a complex phenomenon, and scientists are still trying to figure out its full implications. However, one thing is clear: this isn’t a simple black-and-white issue as the long-term effects of repeated mRNA shots are only now coming into focus.
Health agencies like the CDC and WHO argue that the benefits of vaccination outweigh the risks. But should we ignore potential red flags, especially when they involve changes to our immune system long term? Especially in populations that had virtually no risk from Covid-19 (i.e. children)? Absolutely not.
The science isn’t settled – but nor is this speculation
Elevated IgG4 levels are documented. Multiple studies confirm that repeated mRNA injections lead to a significant increase in IgG4 antibodies (Irrgang et al., 2021). This isn’t speculation—it’s a fact.
Case reports suggest a link. Individuals have developed IgG4-related diseases shortly after getting injected (Uchida et al., 2022). While these cases are rare, as not many practitioners have linked the Covid 19 gene therapy to a certain pathology, they highlight a potential connection that needs further investigation.
The immune response Is complex. The IgG4 switch might be the immune system’s way of adapting to repeated exposure to the spike protein in the vaccines. But this adaptation could come with unintended consequences, including reduced vaccine efficacy and heightened risk of certain diseases. And the most important question is the duration of this fact which we will only know in a decade.
More studies are needed. The science is evolving, and more research is needed to fully understand the implications of this antibody switch. For now, it’s clear that this isn’t a one-size-fits-all situation.
What can we do?
As individuals, the best thing we can do is stay informed. Ask questions if asked to be vaccinated: demand transparency, and weigh the risks and benefits of any medical intervention.
If you yourself have been affected by any of the pathologies above, even months or years after the Covid injections, ask your healthcare providers to assess a potential association. You can test for Covid antibodies (when over 1000 BAU, it is reasonable to assume that you are still producing spike proteins after the injections). You can also get tested for IgG4s (for Covid and generally), for spike proteins (in serum, immune cells, exosomes, body fluids) or for mRNA (in serum, exosomes or any body fluid).
For policymakers and health agencies, it’s crucial to continue monitoring these injections’ long-term effects and be honest about potential risks. Ignoring the elephant in the room won’t make it go away.
Final thoughts
The IgG4 switch is an alarming consequence of repeated Covid-19 mRNA vaccinations. The evidence so far suggests that this phenomenon could have significant implications for immunity, vaccine efficacy, and long-term health. It’s time to have an open, honest conversation about those ‘trade-offs’—and to keep the spotlight on the elephant in the room. This is certainly another red flag for the continuation of the Covid 19 gene therapy and adds to the calls for a moratorium of this technology. Especially considering further promotion of mRNA technologies in the US, Europe, and Russia, we urgently need independent scientists to gather at a roundtable with those pushing for even more use. The World Council for Health has repeatedly called for a moratorium on the technology. This is just the latest, essential piece we’re adding to the puzzle.
