“Most of those vaccinated were between 20 and 59 years old, and the largest number of doses were administered in France ,” explained the researchers, who specified that the vaccines came from Pfizer, Moderna, and AstraZeneca. The results obtained have not reassured healthcare professionals, and even less so patients.
Researchers have observed an increase in cases of Guillain-Barré syndrome and cerebral venous thrombosis following the administration of the first dose of the AstraZeneca vaccine. Guillain-Barré syndrome is primarily characterized by muscle weakness, while venous thrombosis is the formation of a blood clot in a vein, obstructing blood flow throughout the body. French NBA star Victor Wembanyama suffered from the latter condition a few months ago, forcing him to end his season.

The researchers emphasize that further research is needed to determine the link between the vaccine and these side effects.
