Two very rare Covid vaccine side-effects detected in global study of 99 million ( www.theguardian.com )
Results confirm how uncommon known complications are as researchers confirm benefits from vaccines still ‘vastly outweigh the risks’
Two new but exceptionally rare Covid-19 vaccine side effects – a neurological disorder and inflammation of the spinal cord – have been detected by researchers in the largest vaccine safety study to date.
The study of more than 99 million people from Australia, Argentina, Canada, Denmark, Finland, France, New Zealand and Scotland also confirmed how rare known vaccine complications are, with researchers confirming that the benefits of Covid-19 vaccines still “vastly outweigh the risks”.
Researchers working as part of the Global Vaccine Data Network used deidentified electronic healthcare data to compare the rates of 13 brain, blood and heart conditions in people after they received the Pfizer, Moderna or AstraZeneca vaccine with the rate that would be expected of those conditions in the population before the pandemic.
