Summary
This study followed 293 people with autoimmune diseases and healthy volunteers to see how COVID-19 infection or vaccination affects their immune system, inflammation, and blood vessels. Participants were grouped based on their COVID-19 history and had up to 5 visits over 12-18 months, including blood tests, heart and lung checks, and sometimes a special scan. The goal was to understand how the body responds to COVID-19 in people with autoimmune conditions.
