Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The primary objective is to determine whether the use of immunomodulating medications have an impact on the ability to mount and sustain an immune response to SARS-CoV-2 spike protein following mRNA vaccination in patients with MS when compared to healthy controls not receiving immunomodulating medications. We hypothesize that the use of immunomodulators in MS patients may eliminate or reduce the level of protective immune response, and/or shorten the duration of the protective response.
