Beta interferons (Avonex, Betaseron, Extavia, Plegridy, Rebif), any glatiramer acetate (Copaxone, Glatopa and generic glatiramer), Aubagio, Bafiertam, generic dimethyl fumarate, Tecfidera, Vumerity, and Tysabri
Do not delay starting one of these medicines for your vaccine injection. If you are already taking one of these DMTs, no adjustments of your DMT administration are recommended2.
Sphingosine 1 phosphate receptor modulators (Gilenya, Mayzent, Zeposia, Ponvory)
If you are about to start one of these medicines, consider getting fully vaccinated* 2-4 weeks or more prior to starting your medicine. If you are already taking Gilenya, Mayzent, Zeposia or Ponvory, continue taking as prescribed and get vaccinated as soon as the vaccine is available to you.
*Fully vaccinated= two doses of the mRNA (Pfizer BioNTech or Moderna) or one dose of the vector vaccine (J&J)
Alemtuzumab (Lemtrada)
If you are about to start Lemtrada, consider getting fully vaccinated* 4 weeks or more before starting Lemtrada. If you are already taking Lemtrada, consider getting vaccinated 24 weeks or more after the last Lemtrada dose2. If you are due for your next treatment course, when possible, resume Lemtrada 4 weeks or more after getting fully vaccinated. This suggested scheduling is not always possible and getting the vaccine when it becomes available to you may be more important than coordinating timing of the vaccine with your Lemtrada dose. Work with your MS healthcare provider to determine the best schedule for you.
*Fully vaccinated= two doses of the mRNA (Pfizer BioNTech or Moderna) or one dose of the vector vaccine (J&J)
Oral cladribine (Mavenclad)
If you are about to start Mavenclad, consider getting fully vaccinated* 2-4 weeks prior to starting Mavenclad. If you are already taking Mavenclad, the currently available limited data does not suggest that timing of the vaccine in relation to your Mavenclad dosing is likely to make a significant difference in vaccine response. Getting the vaccine when it becomes available to you may be more important than coordinating timing of the vaccine with your Mavenclad treatment. If you are due for your next treatment course, when possible, resume Mavenclad 2-4 weeks after getting fully vaccinated*. Work with your MS healthcare provider to determine the best schedule for you.
*Fully vaccinated= two doses of the mRNA (Pfizer BioNTech or Moderna) or one dose of the vector vaccine (J&J)
Anti-CD20 monoclonal infusions (Ocrevus and Rituxan and biosimilars)
If you are about to start Ocrevus or Rituxan, consider getting fully vaccinated* 2-4 weeks or more prior to starting the infusions. If you are already taking Ocrevus or Rituxan, consider getting vaccinated 12 weeks or more after the last DMT dose3. When possible, resume Ocrevus or Rituxan 4 weeks or more after getting fully vaccinated*. This suggested scheduling is not always possible and getting the vaccine when it becomes available to you may be more important than timing the vaccine with your MS medicine. Work with your MS healthcare provider to determine the best schedule for you.
*Fully vaccinated= two doses of the mRNA (Pfizer BioNTech or Moderna) or one dose of the vector vaccine (J&J)
Ofatumumab (Kesimpta)
If you are about to start Kesimpta, consider getting fully vaccinated 2-4 weeks or more prior to starting Kesimpta. If you are already taking Kesimpta, there is no data to currently guide timing of the vaccine in relation to your last DMT injection. When possible, resume Kesimpta injections 2-4 weeks after getting fully vaccinated. This suggested scheduling is not always possible and getting the vaccine when it becomes available to you may be more important than timing the vaccine with your MS medicine. Work with your MS healthcare provider to determine the best schedule for you.
*Fully vaccinated= two doses of the mRNA (Pfizer BioNTech or Moderna) or one dose of the vector vaccine (J&J)
High-dose steroids
Consider starting the vaccine injection(s) at least 3-5 days after the last dose of steroids.
