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

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?

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

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

“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.
