COVID-19: Understanding What We Know After Five Years

A national lockdown was implemented on March 17, 2020. Although it was lifted less than two months later, wearing a mask became mandatory.
At the same time, authorities — in partnership with the Pasteur Institute — began planning a massive vaccination campaign.

Many Questions Remain (4/10)

Several pharmaceutical companies, including Pfizer, AstraZeneca, Moderna, and Johnson & Johnson, developed vaccines in record time.
This raised many questions and debates concerning their safety, efficiency, and long-term effects.

Confirmed Side Effects (5/10)

After millions of doses administered and almost five years of data, medical specialists have reported known adverse effects such as high blood pressure, myocarditis/pericarditis, allergic reactions, and heavy menstrual bleeding.
Most of these remain rare but are documented in scientific literature.

Serious Side Effects? (6/10)

To this day, some people — including certain scientists — continue to question whether COVID-19 vaccines may be linked to various health conditions.
A recent large-scale study examined this question further.

This study was conducted 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.
Its findings were published in the scientific journal Vaccine.
