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

The previously-unknown condition - 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 the research will be to ascertain how widespread the condition is and who is most at risk.
