Official title

Immunogenicity of COVID-19 Vaccines in MS Patients on B-cell Depleting Therapy

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

SARS CoV-2 is the virus responsible for the pandemic COVID-19, which has resulted in nearly five million deaths worldwide since its spread in the beginning of 2020. In the United States, there are now two emergency use authorized vaccines that make use of messenger ribonucleic acid (mRNA) based technology that are highly effective for preventing COVID. However, because multiple sclerosis is an autoimmune condition, many individuals with multiple sclerosis take medicines that affect the immune system. The investigators are not sure whether individuals on certain MS medications, including medications that lower a type of immune cell called B lymphocytes, will form as robust of a response to the vaccines. In this study, the investigators will be gathering more information about effectiveness of these vaccines and bloodwork that looks at antibodies and other markers of vaccine response and by asking patients about COVID-19 infections.
