A new study lead by a Mayo Clinic doctor suggests that individuals who were injected with the Johnson & Johnson COVID-19 vaccine are 3.5 times more likely to get Cerebral Venous Sinus Thrombosis, a potentially fatal blood clot in the brain.
According to the study, individuals who were injected with the Johnson & Johnson COVID-19 shot are 3.5 times more likely to get a Cerebral Venous Sinus Thrombosis (CVST), a potentially fatal blood clot in the brain, when compared to the pre-pandemic general population.
WebMD explains that CVST “is a type of rare blood clot that forms in the venous sinuses in your brain” that “can block the blood in your brain from draining out toward your heart” causing “a type of stroke” that “stems from internal bleeding.” The resource explains that “CVST can be life-threatening” and warns readers, “You’ll need immediate medical attention.”
The study was lead by Dr. Aneel A. Ashrani, a medical doctor and researcher at the Mayo Clinic’s Department of Internal Medicine. The research was funded by the National Institutes of Health. It was published in The Journal of the American Medical Association (JAMA), a peer-reviewed medical journal. Despite the increased risk, researchers insist the “absolute CVST risk was still low.”
The Mayo Clinic researchers also found that women between the ages of 30 and 64 were at the highest risk of the potentially life threatening blood clots.
While the Johnson & Johnson injection only accounts for a reported 4% of the reported 400 million people who’ve been injected with COVID-19 vaccines, many individuals chose to get injected with their shot because it only required a single dose to be considered “fully vaccinated.” This is no longer true, as booster shots for both the Johnson & Johnson and Moderna vaccines have now been approved.
