Summary

This study followed 163 people with chronic inflammatory rheumatism (like rheumatoid arthritis) who had a recent COVID-19 infection. Researchers measured their antibody levels over two years to see how immunosuppressive drugs affect antibody persistence. The goal was to better understand immune protection and guide vaccination strategies for this group.
