[Indications for varicella zoster and herpes zoster vaccination in multiple sclerosis: current situation]. / Varicella-zoster- und Herpes-zoster-Impfindikation bei Multipler Sklerose: aktuelle Situation.

In patients with multiple sclerosis (MS) primary varicella zoster virus (VZV) infections (chickenpox) or reactivation (shingles, herpes zoster) pose a particular challenge for neurologists and physicians in everyday clinical practice. On the one hand the various immunotherapeutic agents for treatment of MS have differently expressed risks for VZV-associated infections and on the other hand the currently available vaccination strategies (dead vs. live vaccines, single vs. combination vaccines) require an individualized approach. Moreover, in addition to the optimal timing of vaccination during the course of MS, the appropriate vaccine and, where indicated, the use of antiviral drugs should be determined.
