For years, thousands of Americans who suffered debilitating side effects after getting the Covid vaccine were told there was no evidence the shot was linked.
Some were branded antivaxxers, others told their symptoms were imagined or related to other conditions, like long Covid.
But that changed this week.
On Wednesday, a team from Yale University known for their rigorous work revealed the mRNA shots can cause a previously unknown condition known as 'post-vaccination syndrome.'
The syndrome appears to cause brain fog, dizziness, tinnitus, extreme fatigue and biological changes to patients' immune systems.
