A Canadian researcher claims she faced suppression during the pandemic after uncovering potential severe heart risks associated with Covid vaccines, but now feels validated four years later.

Dr. Jessica Rose, an immunology expert from Memorial University of Newfoundland, revealed that her 2021 study, which identified a link between Covid vaccines and myocarditis, was inexplicably retracted from the journal Current Problems in Cardiology only three weeks following its publication.

Myocarditis refers to a serious heart inflammation that can lead to symptoms like chest pain, breathing difficulties, fatigue, abnormal heart rhythms, and leg swelling. In extreme cases, it can cause heart failure, blood clots, strokes, or even sudden death.

Rose’s research utilized data from a government-managed database monitoring vaccine side effects, highlighting a marked rise in heart damage incidents weeks after Covid vaccinations.

The study revealed that myocarditis rates were 19 times higher among boys aged 12 to 15 just eight weeks post-vaccination. Tragically, six individuals, including two children, succumbed to myocarditis following their inoculations.

In an interview with the Daily Mail, Rose expressed her belief that the study’s removal was an act of censorship. She pointed out that her work was discredited and taken down mere days before she was scheduled to testify at a vaccine safety hearing by the US Food and Drug Administration on October 26, 2021.

‘Anything that goes against the narrative of ‘safe and effective’ in the context of those products was heavily censored. That’s what this was about,’ the Canadian researcher alleged. There was absolutely no reason given by the editor or publisher for the withdrawal.’

Now, researchers at Stanford Medicine have released similar findings in a new study, published in December 2025, which found that Covid mRNA vaccines can lead to myocarditis.

‘I deserve an apology for this,’ Rose declared on X after the report by Stanford Medicine.

She compared the actions of controversial fact-checking organizations to a ‘cartel’ protecting certain narratives, allegedly influenced by money from pharmaceutical companies. 

She claimed she and other Covid vaccine researchers were still being harassed for identifying risk factors.

A spokesperson for Current Problems in Cardiology’s publisher, Elsevier, told Daily Mail that the removal of the study was ‘in line with our standard policies.’

‘This article has been withdrawn at the request of the author(s) and/or editor. The publisher apologizes for any inconvenience this may cause,’ the spokesperson added.

Rose has denied ever requesting that her work be removed and accused multiple websites, including PubPeer, of targeting scientific papers that question the official narrative of Covid vaccines being completely safe for use.

She called it unfair ‘post-peer review’ attacks driven by groups who want to silence dissenting research, rather than genuine efforts to improve science.

The 2025 Stanford study, which examined blood samples, cell tests, mice, and human heart models grown in labs, also found that mRNA Covid vaccines, especially the Pfizer and Moderna jabs, created a risk of triggering myocarditis, with young men suffering symptoms as soon as three days after vaccination.

The scientific journal Current Problems in Cardiology withdrew Rose’s paper five days before she was to reveal the research at an FDA meeting in 2021

Both Rose and Stanford Medicine have accused PubPeer of making false accusations against scientists, which has influenced various journals to withdraw scientific papers without verified proof of a mistake in the research.

In November, a team at Stanford Medicine also alleged that the majority of PubPeer’s accusations against the university’s Südhof neuroscience research lab have come from four commentators who have no formal scientific background or training.

Thomas Südhof, a neuroscientist and Nobel Prize winner, and his lab team wrote in a statement: ‘Regrettably, PubPeer and other social media sites are non-transparent, censor responses, ‘flag’ as many papers as possible to force corrections and retractions, and use anonymous commentators.’

‘PubPeer critics levelled unfounded accusations that ‘flag’ papers even though there are no errors,’ the Stanford team claimed. ‘These false allegations may have led to unwarranted paper retractions that destroy valuable data and promising careers.’ 

In a statement to the Daily Mail, PubPeer denied any claims that its team sought to censor certain fields of scientific or medical study. 

‘Those accusations are ridiculous. We provide a platform for scientific discussion, we don’t make arguments one way or another,’ a spokesperson said.

During the pandemic, Rose co-authored the research paper entitled ‘A Report on Myocarditis Adverse Events in the US Vaccine Adverse Events Reporting System (VAERS) in Association with COVID-19 Injectable Biological Products.’

VAERS allows doctors, patients, and others to report possible side effects after receiving all types of vaccinations, including the Covid jabs.

It’s designed to spot early ‘safety signals,’ patterns that might show a problem and need more investigation.

Rose, who also has a PhD in computational biology, and her co-author, Peter McCullough, a US cardiologist from Baylor University in Texas, found that myocarditis risk was higher after the second Covid vaccine dose, but did not determine the cause.

‘This was alarming to me because if this is showing up in this pharmacovigilance database, is it showing up in others around the world? Is it showing up clinically?’ the study author explained.

‘It was exactly what VAERS is designed to do, which is detect safety signals for further analysis… It was functioning perfectly, and the signal was there. It was emergent. It was obvious.’

Inflammation of the heart, also known as myocarditis, can cause symptoms ranging from fever to death in extreme cases

While the exact cause of the inflammation wasn’t found in 2021, the new study by Stanford revealed that mRNA vaccines, like the Covid jab, trigger a specific immune overreaction in some people.

After the shot, researchers found certain immune cells released two chemicals, CXCL10 and IFN-γ, that worked together to inflame and damage heart muscle cells.

However, the Stanford team cautioned that patients were still 10 times more likely to develop myocarditis from being infected with Covid than they were from taking the vaccination.

Joseph Wu, MD, PhD, the director of the Stanford Cardiovascular Institute, added that: ‘COVID’s worse. Without these vaccines, more people would have gotten sick, more people would have had severe effects and more people would have died.’

After Rose’s paper was officially peer-reviewed and published on September 30, 2021, the researcher said she was notified it was being removed from public view just before her scheduled appearance at the FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting. 

Rose said neither she nor her co-author requested the study be taken down, and no claims of fraud, plagiarism, or factual errors were made against the research.

The VRBPAC meeting was an all-day session where independent experts reviewed Pfizer’s data on its lower-dose Covid-19 vaccine for children between five and 11 years old.

Despite Rose voicing her concerns and revealing her research, 17 experts voted unanimously to recommend emergency use authorization for Covid vaccines among young children.

Rose revealed that no one from the FDA, CDC, or Biden Administration directly contacted her to challenge the findings on myocarditis before the study was removed.

Rose noted that she’s continuing her research into Covid vaccine injuries and risk factors, and has already had a new paper peer-reviewed and published in the journal Autoimmunity on unsafe levels of DNA material in the jabs.
