Official title

Evaluating the Effect of Disease Modifying Therapy on Antibody Response to COVID19 Vaccination in People With Multiple Sclerosis

Brief summary

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

This observational study is intended to evaluate the effect of disease modifying therapies on antibody responses to the mRNA-1273 vaccine (Moderna) for COVID-19. We hypothesize that the use of certain disease modifying therapies, particularly ocrelizumab, will mute and/or shorten the duration of humoral response to mRNA vaccines.
