Explosive revelations as a study conducted at FDA’s own lab found residual DNA levels exceeded safety limits by 6 to 470 times. Experts say it’s a ‘smoking gun.’

An explosive new study conducted within the U.S. 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,” criticising 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.

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 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.

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.

Canadian veteran challenges conviction for guarding War Memorial during Freedom Convoy

When the convoy first came to Ottawa, allegations were floated that the memorial had been desecrated. After learning of this, Evely quickly organized a group of veterans to stand guard around the clock to protect the area.

A Canadian veteran appealed to the Ontario courts after he was convicted for organizing a guard around the National War Memorial during the Freedom Convoy.

In an October press release, the Justice Centre for Constitutional Freedoms (JCCF) announced that an appeal has been filed in the Ontario Court of Appeals on behalf of Master Warrant Officer (Ret’d) Jeffrey Evely over his conviction for mischief and obstructing police while on his way to guard the Ottawa War Memorial during the 2022 Freedom Convoy.

“By locking down large sections of downtown Ottawa, the police were effectively preventing all civilians from accessing public areas and greatly exceeded their powers under the common law,” constitutional lawyer Chris Fleury explained.

“This case raises issues that have implications for protests across the province and the country. We are hopeful that the Ontario Court of Appeal will agree and grant leave to appeal,” he added.

The appeal argues that police overstepped their authority in their response to the 2022 protest of COVID mandates. Police actions at the time included locking down the Ottawa core, establishing checkpoints, and arresting protesters.

In September 2024, Everly was convicted of mischief and obstruction after his involvement in the 2022 Freedom Convoy, which protested COVID mandates by gathering Canadians in front of Parliament in Ottawa.

As LifeSiteNews previously reported, when the convoy first came to Ottawa, allegations were floated that the memorial had been desecrated. After learning of this, Evely quickly organized a group of veterans to stand guard around the clock to protect the area.

However, under former Prime Minister Justin Trudeau’s use of the Emergencies Act, many parts of downtown Ottawa were blocked to the public, and a vigilant police force roamed the streets.

It was during this time that Evely was arrested for entering a closed off section of downtown Ottawa during the early hours of February 19, 2022. He had been on his way to take the 4:25 a.m. shift protecting the Ottawa War Memorial.

He was forcibly pushed to the ground, landing face first. The veteran was then arrested and charged with mischief and obstructing police.

At the time, the use of the EA was justified by claims that the protest was “violent,” a claim that has still gone unsubstantiated.

In fact, videos of the protest against COVID regulations and shot mandates show Canadians from across the country gathering outside Parliament engaged in dancing, street hockey, and other family-friendly activities.

Indeed, the only acts of violence caught on video were carried out against the protesters after the Trudeau government directed police to end the protest. One such video showed an elderly women being trampled by a police horse.

While the officers’ actions were originally sanctioned under the EA, Federal Court Justice Richard Mosley ruled that Trudeau was “not justified” in invoking the EA, forcing Crown prosecutors to adopt a different strategy.

Now, Crown prosecutors allege that the common law granted police the authority to stop and detain Evely, regardless of the EA.

However, Evely and his lawyers have challenged this argument under section 9 of the Canadian Charter of Rights and Freedoms, insisting that his “arrest and detention were arbitrary.”

Earlier this month, Freedom Convoy organizers Tamara Lich and Chris Barber were sentenced to 18-month house arrest after a harrowing 25-month trial process. Many have condemned the sentence, warning it amounts to “political persecution” of those who stand up to the Liberal government.

Freedom Convoy leader Tamara Lich says ‘I am not to leave the house’ while serving sentence

‘I was hoping to be able to drop off and pick up my grandsons from school, but apparently that request will have to go to a judge’

Freedom Convoy leader Tamara Lich detailed her restrictive house arrest conditions, revealing she is “not” able to leave her house or even pick up her grandkids from school without permission from the state.

Lich wrote in a X post on Wednesday that this past Tuesday was her first meeting with her probation officer, whom she described as “fair and efficient,” adding that she was handed the conditions set out by the judge.

“I was hoping to be able to drop off and pick up my grandsons from school, but apparently that request will have to go to a judge under a variation application, so we’ll just leave everything as is for now,” she wrote.

Lich noted that she has another interview with her probation officer next week to “assess the level of risk I pose to re-offend.”

“It sounds like it’ll basically be a questionnaire to assess my mental state and any dangers I may pose to society,” she said.

While it is common for those on house arrest to have to ask for permission to leave their house, sometimes arrangements can be made otherwise.

On October 7, Ontario Court Justice Heather Perkins-McVey sentenced Lich and Chris Barber to 18 months’ house arrest after being convicted earlier in the year convicted of “mischief.”

Lich was given 18 months less time already spent in custody, amounting to 15 1/2 months.

As reported by LifeSiteNews, the Canadian government was hoping to put Lich in jail for no less than seven years and Barber for eight years for their roles in the 2022 protests against COVID mandates.

Lich said that her probation officer “informed me of the consequences should I breach these conditions, and I am not to leave the house, even for the approved ‘necessities of life’ without contacting her to let her know where I’ll be and for how long,” she wrote.

“She will then provide a letter stating I have been granted permission to be out in society. I’m to have my papers on my person at all times and ready to produce should I be pulled over or seen by law enforcement out and about.”

Lich said that the probation officer did print a letter “before I left, so I could stop at the optometrist and dentist offices on my way home.”

She said that her official release date is January 21, 2027, which she said amounts to “1,799 days after my initial arrest.”

As reported by LifeSiteNews, Lich, reflecting on her recent house arrest verdict, said she has no “remorse” and will not “apologize” for leading a movement that demanded an end to all COVID mandates.

LifeSiteNews reported that Conservative Party leader Pierre Poilievre offered his thoughts on the sentencing, wishing them a “peaceful” life while stopping short of blasting the sentence as his fellow MPs did.

In early 2022, the Freedom Convoy saw thousands of Canadians from coast to coast come to Ottawa to demand an end to COVID mandates in all forms. Despite the peaceful nature of the protest, Trudeau’s government enacted the never-before-used Emergencies Act (EA) on February 14, 2022.
