Researchers observed an increase in cases of Guillain-Barré syndrome, as well as cerebral venous thrombosis, following the first dose of the AstraZeneca vaccine.
Guillain-Barré syndrome is characterized primarily by muscle weakness, while venous thrombosis is the formation of a blood clot in a vein, obstructing proper blood flow. French NBA star Victor Wembanyama suffered from the latter a few months ago, forcing him to end his season.

Furthermore, all the vaccines significantly increased the risk of myocarditis and pericarditis (inflammation affecting the myocardium, the muscle responsible for heart contraction and blood circulation).
“Other red flags have been identified that require further examination,” the journal states. The researchers emphasize that more studies are needed to understand the link between the vaccine and these side effects.
