Warning: People vaccinated against COVID-19 may… See more

To this day, many people, including scientists, disagree that the    COVID -19  vaccine    causes multiple    illnesses  . However, a study conducted a few months ago showed that the      COVID-19 vaccine can cause serious side effects.

The study was conducted by the   Global Vaccine Data Network    with data from over 99 million people. Eight countries were at the center of this project (Argentina, Australia, Canada, France, Denmark, Finland, New Zealand, and Scotland), and the results were published in the journal   Vaccine  .

“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 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 characterized primarily 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.

In addition, all the vaccines   significantly increased the risk of myocarditis and pericarditis (inflammation of the myocardium, the muscle responsible for heart contraction and blood circulation). “  Other concerns were identified that require further investigation  ,” the review states. The researchers emphasize that more research is needed to determine the relationship between the vaccine and these side effects.
