Study Finds Small Increase in Heart and Brain Conditions Linked to COVID Vaccines
The largest COVID vaccine study to date, analyzing 99 million vaccinated individuals across eight countries, found a slight increase in neurological, blood, and heart-related medical conditions associated with the vaccine, including a higher risk of myocarditis with mRNA vaccines and blood clots in the brain with viral-vector vaccines. The study also identified an increased likelihood of Guillain-Barre syndrome and other rare potential vaccine safety signals. Experts emphasize that while these risks are rare, the benefits of vaccination in reducing the risk of severe COVID-19 outweigh them, and urge careful consideration of risks and benefits by both patients and healthcare providers.
