Yale University researchers detected the spike protein from the COVID-19 vaccine in the blood of at least one person 709 days after vaccination — a significantly longer time than previously measured.

The research team also found that many people thought to be experiencing long COVID may instead be suffering from post-vaccination syndrome (PVS) caused by the spike protein from the COVID-19 vaccines.

PVS symptoms, similar to those of long COVID, commonly include brain fog, dizziness and tinnitus.
