In the most extensive vaccine safety study to date, involving more than 99 million people across eight countries, researchers have brought to light some new findings about the COVID-19 vaccines. While the emergence of two exceptionally rare side effects may raise eyebrows, the overarching message is clear: the advantages of getting vaccinated against COVID-19 massively overshadow the risks.

The Global Vaccine Data Network's deep dive into electronic healthcare data has yielded some reassuring news about the vaccines developed by Pfizer, Moderna, and AstraZeneca. This vast study spanned Australia, Argentina, Canada, Denmark, Finland, France, New Zealand, and Scotland, offering a broad yet precise snapshot of vaccine safety worldwide.


  • Study Scope: Over 99 million individuals from eight countries.
  • Vaccines Analyzed: Pfizer, Moderna, and AstraZeneca.
  • Confirmed Rare Side Effects: Myocarditis, pericarditis, Guillain-Barré syndrome, and cerebral venous sinus thrombosis.
  • Newly Identified Side Effects: Acute disseminated encephalomyelitis and transverse myelitis linked to the AstraZeneca vaccine.
  • Risk Ratio: 0.78 cases of acute disseminated encephalomyelitis and 1.82 cases of transverse myelitis per million doses.

This research not only reaffirmed the rarity of known vaccine complications but also introduced two new side effects associated with the AstraZeneca vaccine: acute disseminated encephalomyelitis and transverse myelitis. However, it's crucial to put these findings into perspective. The risks associated with these conditions are minuscule compared to the protective benefits that vaccines offer against COVID-19.

Interestingly, the study also highlighted that the risk of myocarditis is higher from a natural COVID infection than from vaccination. This further underscores the vaccines' role in safeguarding public health, emphasizing that the path to ending the pandemic lies through widespread vaccination.

The key takeaway? While no medical intervention is without risk, the COVID-19 vaccines have been shown to be remarkably safe and effective. By choosing to get vaccinated, you're not just protecting yourself but also contributing to the global fight against the pandemic. The benefits, as this study vividly illustrates, vastly outweigh the risks.
