Multiple Sclerosis Clinical Trial
Official title:
Evaluating the Immune Response to COVID19 Vaccination in Immunodeficient Patients
The purpose of this study is to understand the immune response to coronavirus disease-19 (COVID-19) vaccination in patients on B-cell depleting therapies (BCDT) over time, which in the future may help to inform clinical decision making in this patient population.
This will be a prospective, observational cohort study consisting of individuals with autoimmune diseases who are undergoing treatment with anti-CD20 medications at the time they receive a vaccine against COVID-19. Control groups will include healthy individuals, individuals with autoimmune diseases on other immunomodulators, and individuals with autoimmune diseases not on immunotherapy. Participants will undergo serial blood draws and saliva collections at prespecified time points surrounding vaccination. A subset of agreeable participants will undergo skin biopsy within days of the first vaccination, with the option to repeat skin biopsy after the second vaccination. Additional blood, saliva and skin biopsy specimens may be obtained after booster vaccinations or after known COVID19 infections . Specimens collected will be used for studies aimed at (1) understanding the pathobiology of neurologic/inflammatory/immune diseases and the immunologic response to COVID-19 vaccination, (2) identifying how and why treatments used for neurologic/immune diseases may impact the effectiveness of vaccination, and (3) identifying dermatologic manifestations of the immunologic response to the COVID-19 mRNA vaccine. The investigators are investigating both the production of antibodies against the virus over time and deeply interrogating the T-cell response to vaccination using methods that measure T-cell reactivity to the COVID-19 virus, including single cell RNA sequencing. ;
