Yale scientists link Covid vaccines to alarming new syndrome causing ‘distinct biological changes’ to body

Experts from Yale University have discovered an alarming syndrome linked to the mRNA Covid vaccines.

The previously-unknown condition – which has been dubbed ‘post-vaccination syndrome’ – appears to cause brain fog, dizziness, tinnitus and exercise intolerance.

Some sufferers also show distinct biological changes, including differences in immune cells and the presence of coronavirus proteins in their blood, years after taking the shot.

The condition also appears to reawaken a dormant virus in the body called Epstein-Barr which can cause flu-like symptoms, swollen lymph nodes and nerve issues.

The full results of the small study have not yet been published, and the Yale experts emphasized the results ‘are still a work in progress.’

Yet the findings, from a well-respected institution, suggest more research on post-vaccination syndrome is needed, independent experts said.

The next phase of their research will be to ascertain how widespread the condition is and who is most at risk.

Dr Akiko Iwasaki, study author and immunologist at Yale University, told The New York Times: ‘I want to emphasize that this is still a work in progress.

‘It’s not like this study determined what’s making people sick, but it’s the first kind of glimpse at what may be going on within these people.’ 

The Covid vaccines prevented millions of deaths worldwide and serious side effects are extremely rare – affecting around one in 200,000 people, according to official US data.  

The Covid vaccines have been linked to a small risk of heart damage and Guillain-Barre syndrome, where the immune system attacks nerves, causing pain, fatigue and numbness.

Data from the US Covid vaccine injury compensation program suggested that 14,000 people had filed claims for injury or death they claimed were caused by the Covid vaccine as of December 2024, out of the 270million Americans who received at least one dose of the vaccine.

Dr Paul Offit, a vaccines expert at the Children’s Hospital of Philadelphia, previously told DailyMail.com this highlighted that the vaccines were not dangerous.

He said: ‘The vaccines have been given to billions of people at this point, and there were large prospective placebo-controlled studies that didn’t show these effects.

‘As the vaccines were rolled out, not everyone got them at once… and this staggering would tell you if something is a problem that was not picked up in clinical trials.

‘We picked up myocarditis during this… we even picked up Guillain Barre syndrome, which has a rate after vaccination of around eight in a million. 

‘We would have easily picked up [these excess deaths and purported links to cancer] if true, and we haven’t picked this up.’

CDC data shows only two serious adverse effects have been well established after Covid vaccination – anaphylaxis and myocarditis or pericarditis, two types of heart damage.

It’s unclear how common anaphylaxis is. The heart conditions are rare but exactly how rare is still being debated. A major 2021 study in Israel put the rate at one in 50,000. Other studies have come to vastly different estimates. 

In the new study, Iwasaki’s team collected blood samples from 42 people with this post-vaccination syndrome and 22 people without it between December 2022 and November 2023. 

The team found that people with post-vaccination syndrome had different proporations of some immune cells, though they were unable to link them to specific symptoms. 

The team also looked at 134 people with long Covid, as PVS symptoms overlap with it, as well as 134 healthy vaccine recipients. 

Both people with long Covid and those with PVS seemed to have reactivated Epstein-Barr syndrome. 

More than nine in 10 adults have had Epstein-Barr, a common infection spread through bodily fluids like saliva or semen. 

It causes symptoms like fatigue, fever, and rashes, and once symptoms disappear, the virus remains dormant in the body. 

Though symptoms are mild, the virus has been linked to complications like mononucleosis and multiple sclerosis. 

A 2024 study looked at the conditions most associated with Covid vaccinations. Heart issues like pericarditis and myocarditis were most often linked to the shots 

People with PVS also had elevated levels of Covid spike proteins, which are thought to cause long Covid and result in inflammation throughout the body. 

These levels were even greater than those found in patients with long Covid, a condition with similar symptoms linked to the virus itself.

Dr Iwasaki noted patients with PVS had significantly higher spike proteins than any other participants, including those with long Covid. This was true in patients who received their vaccines between 36 and 709 days prior. 

Dr Iwasaki said mRNA vaccines themselves were unlikely to have caused the proteins to stay in the body so long and noted ‘something else is allowing this sort of late-phase expression of spike protein, and we don’t really know what that is.’ 

The study’s main limitation was its small size, Dr Gregory Poland, emeritus editor of the journal Vaccine and president of Atria Research Institute, told the New York Times. 

However, he added: ‘Despite these limitations, they found interesting data that need further study.

‘Much larger studies of very carefully defined and phenotyped individuals need to take place.’
