COVID-19 vaccines linked to small increases in health conditions

A global study of nearly 100 million COVID-19-vaccinated people in eight countries found small increases in health conditions involving the brain, blood, and heart. The study confirmed links between COVID-19 vaccinations and low risks of myocarditis, pericarditis, Guillain-Barré syndrome, and cerebral venous sinus thrombosis. The study also identified potential safety signals for rare conditions. The research emphasizes the importance of comprehensive vaccine safety monitoring. The study has been published in the journal Vaccine.
