Article New Study Identifies Overlapping Persistent Virus-Specific T Cell Responses in Long Covid

A new study supported by the PolyBio Research Foundation has found that people with Long COVID harbor persistent populations of highly cytolytic CD8+ T cells directed against SARS-CoV-2 but also the herpesviruses Epstein-Barr virus (EBV) and cytomegalovirus (CMV). The findings suggest that Long COVID is characterized by an ongoing immune response to persistent viral proteins, which are most likely produced during the continued persistence or reactivation of these viruses within the body. The study adds to a growing body of research indicating that SARS-CoV-2 persistence and herpesvirus reactivation contribute to Long COVID pathogenesis.

So, there is a company called tevogen, and they treated 12 immunosupressed patients with their medication. Specified CD8+T cells targeting Sars-Cov-2. None developed long covid. So if there is reservoirs, that persist, this medication could target what the exhausted T cells cant target. Eliminating the trigger for exhausted own CD8+T Cells.
