New Research Suggests Cause of Rare Blood-Clotting Side Effect From COVID-19 Vaccine
Epoch Times ^ | 02/16/26 | Marina Zhang

Posted on 02/16/2026 8:26:24 PM PST by SeekAndFind

In early 2021, some patients were developing a rare yet life-threatening condition in which their blood would clot after getting a COVID-19 vaccine.

In these patients, their bodies were mistakenly attacking their own platelets, causing them to clump together and resulting in blood clots and low platelet counts. Researchers didn’t know why.

Now, a new study may offer an answer.

In a study published in The New England Journal of Medicine, researchers in Australia, Germany, and Canada analyzed 100 patients who took adenovirus vaccines and developed vaccine-induced immune thrombotic thrombocytopenia, also known as VITT.

They found that VITT was likely driven by a change in the antibodies, causing them to switch from harmless to harmful.

“This was the missing link that explains how a normal immune response can, in very rare cases, become harmful,” Jing Jing Wang from Flinders University said in a press release.

Harmful Antibodies

When the immune system encounters foreign invaders like viruses, bacteria, and vaccines, which mimic an infection, one way the body fights them off is to mass-produce antibodies.

These antibodies bind to the foreign invader, putting a target on its back so that other immune cells can kill it.

When patients were given the adenovirus vaccine, their bodies produced many antibodies that targeted components of the vaccine.

When antibodies are mass-produced, new changes are introduced to create the optimum antibody that can kill off invaders. In the case of VITT, some antibodies developed a single change that produced a harmful antibody instead.

Since some parts of platelets and adenoviruses share similarities, this single error made the new antibodies more likely to bind to platelets rather than adenoviruses.

“Exactly how or why this specific mutation occurs, I am not sure. It might all just be a random event,” Dr. Theodore Warkentin, a co-author of the study and professor emeritus of pathology and molecular medicine at McMaster University, told The Epoch Times.

These antibodies bind to platelets, forming a mini traffic jam inside blood vessels—essentially a blood clot.

Other Predisposing Factors

The single error is only one part of the story.

Digging back further into patients’ medical histories, researchers found that these patients also had two other contributors: a prior adenovirus infection and a certain genotype.

Most of the patients were able to mount a very fast response to the vaccine, which suggests they were likely infected with adenoviruses before.

Of the 100 VITT patients analyzed, all inherited a common gene that is present in 60 percent of people of European descent, which may explain why VITT was a greater concern in Western countries. In simple terms, many people in these populations carry the gene, and some had prior adenovirus infections that produced adenovirus antibodies.

When they got an adenovirus vaccine, their bodies mounted a stronger reaction than they would if they had not been exposed to adenovirus previously, and a select few then developed harmful changes to their antibodies, leading to VITT.

“We think VITT will only occur in patients who have the genotype,” Warkentin said. However, he added that there can always be exceptions.

His research has found that adenovirus infections can also cause similar blood clotting, and he suspects that other viruses may cause the same condition.

Unpredictable Reactions to Vaccines

The researchers say the finding could allow vaccine manufacturers to create safer formulations that do not cause this dangerous reaction.

Previous research by the same authors established that VITT was likely caused by the adenovirus aspect of the vaccine, not other components.

Other studies have linked COVID-19 infection and mRNA vaccines to rare blood-clotting events, potentially related to spike proteins.

Though this study identified the mechanism for VITT, why the body triggers this reaction is still unknown. Warkentin added that he believes whether a person develops adverse reactions depends largely on chance.

Every person is different, and research shows that a small percentage respond differently than expected because immune responses vary.

They/them are trying to kill off folks of European roots

RARE, my Aunt Fani.

We knew this ... and, even FRAUDci warned that the best ‘vaccine’ was the NATURAL virus/herd immunity, NOT a $hot, years ago.

They’ve know this ... yet, have continued to roll out these dangerous jabs.

“they LITERALLY changed the definition of the word pandemic a few months before they unleashed the world’s greatest psych op.”

The HAD to unleash Covid to justify releasing the lethal shot which had existed for years prior.

Our little dog recently got a rabies shot and is having problems. I will be calling the vet this morning.

“I would have loved to see you tell that to my relative who died from brain cancer soon after getting the shot. He even blamed the shot.”

Article error: “adenovirus vaccines”

The adenovirus vaccine is a pill.

The study was about the adenovirus based vaccines.

The COVID shots we got were mRNA, not adenovirus based.

Article is totally fake.

“When we are in our mother’s womb, our lungs do not function.”

Babies’ lungs exercise via simulated breathing movements.

“There is no respiration”

There absolutely is respiration.

“There were VERY good reasons we FReepers called it the ‘clot shot’.”

Are you referring to the fake propaganda put out by the fake clot doctor?

Not through the lungs. They are the last to develop and the biggest difficulty to overcome in premature births.

Fetal hemoglobin is unique and carries a very high O2 content. Much higher than after birth and throughout life.

Oxygen is transferred from the mother to the fetus through the placenta, an organ attached to the uterine wall, which facilitates gas exchange without mixing their blood supplies. Maternal blood releases oxygen into the intervillous space, which then diffuses into the fetal capillaries within the placenta, moves through the umbilical vein, and enters the fetal circulation.

That is fetal respiration. Not through the lungs.

What is called “fetal breathing is a flow and pumping of amniotic fluid. Amniotic fluid contains very little O2.

“However, in about 30% of the population this hole never closes. If it is open, blood clots that would normally get screened in the lungs and become a pulmonary embolism get pumped directly through the hole and end up in the brain causing strokes. “

You left out the word ‘rarely’.

Oh no.
I’m so very sorry.

Find out which vax she got.

For future reference for all dog people here:

NOBIVAC® 1-Rabies Vaccine for dogs - Merck Animal Health USA
Non-mRNA (traditional) rabies vaccines for dogs are widely available, utilizing killed virus technology to provide immunity. Common, reputable options include Nobivac® 1-Rabies and Nobivac® 3-Rabies (Merck Animal Health), which are inactivated, cell-culture-grown vaccines providing 1- or 3-year protection. These vaccines are non-recombinant and commonly used in veterinary practices.

Key Non-mRNA Rabies Vaccine Options
Nobivac® 1-Rabies & 3-Rabies (Merck): Uses a chemically-inactivated rabies virus, often adjuvanted to enhance the immune response.
RabVac 3 (Boehringer Ingelheim/formerly Pfizer): A killed-virus vaccine labeled for 3-year protection in dogs and cats.
PUREVAX® Rabies (Boehringer Ingelheim): Another option that uses a canarypox vector rather than mRNA technology to express rabies antigens

“This breaks the milk lipid particles up so small that they are rapidly transferred from intestine to bloodstream, acting as lipid transport vehicles for the spiked proteins.”


Absorption Process: Contrary to theories from the 1970s suggesting that homogenized fat and the enzyme xanthine oxidase (XO) are absorbed directly into the blood, subsequent research has shown that this does not occur, and this hypothesis was not validated.
