ClinConnect Summary

This clinical trial is studying how COVID-19 vaccines might affect brain health, particularly focusing on the risk of strokes and other cerebrovascular issues. Researchers want to understand if there is a connection between vaccination and health problems related to blood flow in the brain. This is important because some people have expressed concerns about experiencing strokes after receiving the vaccine, and the goal of this study is to provide reliable information to help ease those worries.

To participate in this study, you should be between the ages of 65 and 74 and have already had a brain MRI as part of a related health study. You won’t be eligible if you have had a stroke or dementia before joining, if you can’t provide consent, or if you have certain medical conditions that prevent you from undergoing an MRI. If you join, you can expect to contribute to valuable research that may help clarify the impact of COVID-19 vaccines on brain health, which can ultimately assist in promoting vaccine acceptance in the community.
