COVID-19 vaccine: four years later, the list of persistent symptoms continues to grow.

 

A look back at Covid-19 (1/10)
In December 2019, a new virus that appeared in China spread rapidly across the world, alarming the highest authorities, notably the World Health Organization (WHO). A highly contagious infectious disease, called COVID-19, has emerged, leading to an unprecedented pandemic.

The first cases diagnosed in France (2/10)
In France, the first cases were diagnosed at the end of January 2020 and the first deaths due to this new virus were recorded around twenty days later.
Confinement (3/10)
A national lockdown was introduced on March 17, 2020. It was lifted a little less than two months later, but wearing a mask became compulsory. The authorities, in collaboration with the Pasteur Institute, are considering a vaccination campaign.

Many questions remain unanswered (4/10)
Several pharmaceutical companies (Pfizer, AstraZeneca, Moderna, Johnson & Johnson, etc.) designed and offered their vaccines in record time. Many questions then arose.

Confirmed side effects (5/10)
After administering millions of vaccines and with almost five years of hindsight, medical specialists have been able to report several adverse effects such as high blood pressure, myocarditis/pericarditis, allergies or heavy menstrual bleeding.

Serious side effects?(6/10)
Even today, many people, including scientists, dispute that the COVID-19 vaccine causes multiple diseases. However, a study conducted a few months ago showed that this vaccine could cause serious side effects.
The study was conducted by the Global Vaccine Data Network among 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.

Words from researchers (8/10)
"Most of the people vaccinated were between 20 and 59 years old, and it was in France that the greatest number of doses were administered", explained the researchers, specifying that the vaccines came from Pfizer, Moderna and AstraZeneca. These results did not reassure health professionals, and even less patients.
Guillain-Barré syndrome and venous thrombosis (9/10)
Researchers observed an increase in cases of Guillain-Barré syndrome and cerebral venous thrombosis after administration of the first dose of the AstraZeneca vaccine. Guillain-Barré syndrome is mainly characterized by muscle weakness, while venous thrombosis is the formation of a blood clot in a vein, obstructing blood flow to the rest of the body. French basketball player Victor Wembanyama suffered from this condition a few months ago, which forced him to end his season.

Further research is needed (10/10)
Additionally, all vaccines significantly increased the risk of myocarditis and pericarditis (inflammation of the myocardium, the muscle responsible for heart contraction and blood flow throughout the body). "Other problems have been identified and require further investigation", the review said. The researchers emphasize that more research is needed to determine the link between the vaccine and these side effects.

Faced with this alarming situation, vaccines against COVID-19 have been urgently developed. After almost five years of observation and analysis, we now know the side effects of the different vaccines received.
