The primary objective of this study is to document immunization status of MS participants after SARS-CoV-2-vaccinations and to evaluate possible effects of disease modifying therapy (DMTs) on the immune status. The secondary objectives of the study are to document longevity of immunization status of MS participants after SARS-Cov-2-vaccinations and to evaluate possible effects of DMTs on the immune status, to assess anti SARS-CoV-2 antibody titers regarding amount and persistence, to document immunization status of MS participants after repeated SARS-Cov-2-vaccinations and to evaluate possible effects of DMTs on the immune status, to document vaccine types used in MS population in Germany and to describe tolerability of SARS-CoV-2 vaccines according to participant's assessment.
