Covid-19 vaccine: four years later, the list of persistent symptoms is growing

 

Return to COVID-19 (1/10)

In December 2019, a new virus that appeared in China spread rapidly throughout the world, alarming the highest authorities, including the World Health Organization (WHO).
A highly contagious infectious disease emerged, called COVID-19, which caused an unprecedented pandemic.

The first diagnosed cases in France (2/10)

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.

The lockdown (3/10)

A national lockdown was instituted on March 17, 2020. It was lifted a little less than two months later, but wearing a mask became mandatory.
The authorities, in collaboration with the Pasteur Institute, began planning a vaccination campaign.

Many questions remain unanswered (4/10)

Several pharmaceutical companies (Pfizer, AstraZeneca, Moderna, Johnson & Johnson, among others) developed and offered their vaccines in record time.
This raised numerous questions and debates regarding their safety and effectiveness.

Confirmed side effects (5/10)

After administering millions of vaccines and with almost five years of hindsight, medical specialists have reported several adverse effects such as high blood pressure, myocarditis/pericarditis, allergic reactions, or heavy menstrual bleeding.

Serious side effects? (6/10)

Even today, many people —including scientists— question whether the COVID-19 vaccine causes multiple illnesses.
However, a study conducted a few months ago showed that this vaccine could cause serious side effects.

The study was carried out by the Global Vaccine Data Network, involving more than 99 million people across eight countries: Argentina, Australia, Canada, France, Denmark, Finland, New Zealand, and Scotland.
The results were published in the scientific journal Vaccine.

Words from the researchers (8/10)

“Most of the vaccinated individuals were between 20 and 59 years old, and France was the country where the highest number of doses were administered,” the researchers explained, specifying that the vaccines came from Pfizer, Moderna, and AstraZeneca.
These results did not reassure health professionals — much less the patients.

Guillain-Barré syndrome and venous thrombosis (9/10)

Researchers observed an increase in cases of Guillain-Barré syndrome and cerebral venous thrombosis after the administration of the first dose of the AstraZeneca vaccine.

Guillain-Barré syndrome is mainly characterized by muscle weakness, while venous thrombosis involves the formation of a blood clot in a vein, obstructing circulation 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.

More research is needed (10/10)

In addition, all vaccines significantly increased the risk of myocarditis and pericarditis— inflammations of the myocardium (the muscle responsible for heart contraction and for circulating blood throughout the body).
“Other issues have been identified that require further research,” notes the journal.

The researchers emphasize that more investigation is needed to determine the relationship between the vaccine and these side effects.

Conclusion

Faced with this alarming situation, COVID-19 vaccines were developed urgently.
After nearly five years of observation and analysis, we now have a better understanding of the side effects of the different vaccines that were administered.
