Question: For individuals with MS who are taking a disease-modifying therapy (DMT) and plan to get both a COVID-19 vaccine as well as a seasonal flu vaccine, do they need to wait a certain amount of time between taking their DMT and between receiving each vaccine?

Answer: We recommend vaccination for COVID-19 and for flu for most people with MS after appropriate discussion with your doctor or primary care provider. The risk of COVID-19, as well as the risk of becoming sick from the flu, generally outweigh any risks associated with vaccination. We also recommend continued safety precautions including masking, handwashing, and avoidance of large indoor gatherings.

You can take the flu vaccine and COVID-19 vaccine on the same day. Trying to time your vaccination and disease-modifying therapy (DMT) relates primarily to the initiation of immunosuppressive DMTs. With some of these therapies, timing may be considered in order to optimize the effect of the vaccination.

For Gilenya® (fingolimod), Kesimpta® (ofatumumab), Lemtrada® (alemtuzumab), Mavenclad® (cladribine), Mayzent® (siponimod), Ocrevus™ (ocrelizumab), Ponvory (ponesimod), Rituxan® (rituximab), and Zeposia® (ozanimod), it’s generally recommended that vaccination be initiated two to four weeks before starting therapy, when possible. When Ocrevus and the experimental MS-therapy Rituxan have already been started, optimal vaccination response appears to occur when vaccination is given approximately four weeks before the next infusion. However, such timing may be difficult, and therefore in many instances, vaccination can be performed when available.

In addition, the COVID-19 vaccine and most flu vaccines are non-live vaccinations, and as noted above, these should be performed at least two to four weeks before starting immunosuppressive therapies if possible. While we generally do not recommend live vaccinations to individuals with MS if they can be avoided, live vaccinations should be performed at least four to six weeks before initiation of immunosuppressive therapies.

    I have MS. I have received two vaccines one for the flu and one for tetanus. In both cases they effected my optic nerve and I lost my sight. After large amounts of steroids I regained some sight. Considering this background should I take Covid 19 vaccination?

      Hello David,
      Thank you for reaching to to MSAA, and we are sorry to hear about the challenges you have had with your optic nerve. We recommend reaching out to your physician to discuss your health background and a COVID-19 vaccine. Best of luck.
