Rapid Vaccine Development
Pharmaceutical companies like Pfizer, AstraZeneca, Moderna,
and Johnson & Johnson developed Covid-19 vaccines with
“unprecedented speed,” raising public questions and concern.
Reported Side Effects
Millions of doses and nearly five years of observation have confirmed adverse effects,
including “high blood pressure, myocarditis, pericarditis, allergic reactions,
and significant menstrual bleeding.” The link to serious illnesses remains debated.
Large-Scale Study
A study by the Global Vaccine Data Network, covering over 99 million people in eight countries,
found evidence that vaccines can lead to serious adverse events.
Most participants were aged 20–59, with France administering the most doses.
Findings and Implications
The research, published in Vaccine, examined Pfizer, Moderna, and AstraZeneca vaccines.
Researchers noted the results “offered little reassurance,”
prompting concern among healthcare professionals and patients alike.
