The purpose of this study is to identify if there is a relationship between multiple sclerosis disease-modifying therapy exposure, immunodeficiencies, and infection risk in subjects living with MS. By understanding this relationship future studies can be designed to create a model of immunosenescence in multiple sclerosis, which could help healthcare providers to predict and assess health risks. Preventative strategies can then be tested to look for ways to prevent these immune-related risks.
