Faced with this alarming situation, COVID-19 vaccines were developed urgently. After almost five years of observation and analysis, we now know the side effects of the different vaccines we have received.
1/10 A review of covid 19
In December 2019, a novel virus originating in China spread rapidly around the world, alarming the highest authorities, including the World Health Organization (WHO). A highly contagious infectious disease called COVID-19 emerged, along with an unprecedented pandemic.

In France, the first cases were diagnosed at the end of January 2020 and the first deaths caused by this new virus were recorded about twenty days later.
3/10 The lockdown
A nationwide lockdown was imposed on March 17, 2020. It was lifted just under two months later, but mask-wearing became mandatory. Authorities, in collaboration with the Pasteur Institute , are considering a vaccination campaign .
4/10 Many questions
Several pharmaceutical companies (Pfizer, AstraZeneca, Moderna, Johnson & Johnson, etc.) designed and offered their vaccines in record time. This was followed by numerous questions.

7/10 A study of more than 99 million people
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 .
8/10 The researchers’ words
“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.
9/10 Guillain-Barré syndrome and venous thrombosis
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.
