Several pharmaceutical companies (Pfizer, AstraZeneca, Moderna, Johnson & Johnson, among others) designed and proposed their vaccines in record time. This then led to numerous questions and concerns.
Confirmed adverse effects (5/10)
After millions of vaccines administered and almost five years of perspective, specialists in the medical sector have been able to point out several adverse effects, such as high blood pressure, myocarditis/pericarditis, allergies or even heavy menstrual bleeding.
Serious side effects? (6/10)
To this day, many people, including scientists, disagree with the idea that the Covid vaccine is the cause of various illnesses. However, a study a few months ago demonstrated that the Covid-19 vaccine can cause serious side effects.

A study of more than 99 million people (7/10)
The study was conducted by the Global Vaccine Data Network on more than 99 million people. Eight countries participated in this project (Argentina, Australia, Canada, France, Denmark, Finland, New Zealand, and Scotland), and the results were published in the journal Vaccine .

The researchers’ words (8/10)
“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 did not reassure healthcare professionals, much less patients.
Guillain-Barré syndrome and venous thrombosis (9/10)
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.
More research is needed (10/10)
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.
