Largest Multi-Country COVID Study Links Vaccines to Potential Adverse Effects
21st February 2024
A new study on COVID-19 vaccines that looked at nearly 100 million vaccinated individuals affirmed the vaccines’ previously observed links to increased risks for certain adverse effects including myocarditis and Guillain-Barré syndrome.
The researchers noted in their analysis that COVID-19 infections have consistently been found to be more likely to cause the conditions observed in this study than vaccinations, adding that factor should be considered when weight the risk-to-benefit ratio of immunization.
The study was conducted by the Global COVID Vaccine Safety project and took into account 99,068,901 vaccinated individuals across eight countries: Argentina, Australia, Canada, Denmark, Finland, France, New Zealand and Scotland.
The report specifically looked at adverse events following administration of the Pfizer, Moderna and AstraZeneca vaccines.
