Persistent levels of spike protein from COVID-19 vaccines could be associated with a range of chronic symptoms like excessive fatigue, brain fog and muscle aches, according to a Yale University study published Wednesday.
The study describes these symptoms and others — including tingling and numbness, exercise intolerance and difficulty concentrating — as post-vaccine syndrome or PVS. Other symptoms included trouble falling or staying asleep, nerve damage, muscle aches, anxiety, tinnitus and burning sensations. The study was published as a preprint, meaning it has not yet found a home in a scientific journal and has yet to be vetted by outside scientists via peer review.
The researchers studied 42 individuals they diagnosed with PVS. The researchers tested for dozens of potential biological signatures of the syndrome using serology, or blood tests, uncovering a range of hypotheses about the underlying causes.
The researchers hesitated to pinpoint any one single cause, emphasizing that further studies are needed.
But perhaps the most striking clue the researchers picked up was significantly higher circulating levels of spike protein as compared to the control group. Individuals vaccinated 600 to 700 days prior had more elevated levels of spike protein than other participants who had been vaccinated more recently.
However the study only measured each individual’s spike protein levels once, thus could not determine whether the spike protein was increasing over time.
“This suggested that prolonged antigen persistence might be associated with PVS in a subgroup of patients,” the study reads.
