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.
Health Conditions
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.
Medical Literature & Resources
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.
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. The vaccines examined were produced by Pfizer, Moderna, and AstraZeneca.
These results added to the ongoing debates among healthcare professionals and patients alike.
Guillain-Barré Syndrome and Venous Thrombosis (9/10)
Researchers observed an increase in cases of Guillain-Barré syndrome (GBS) and cerebral venous thrombosis (CVT) following the first dose of the AstraZeneca vaccine.
