COVID vaccines from companies like Pfizer, Moderna and AstraZeneca have been linked to rare occurrences of heart, brain and blood disorders, according to the largest vaccine study to date.
Researchers from the Global Vaccine Data Network analyzed 99 million people who received jabs in eight countries and monitored for increases in 13 medical conditions, Bloomberg News reported.
The study, which was published in the journal Vaccine last week, found the vaccines were linked to a slight spike in neurological, blood and heart-related medical conditions.
