COVID-19 vaccine guidance for people living with MS

People living with multiple sclerosis (MS) are seeking peace of mind on the safety and effectiveness of the COVID-19 vaccines. In response, the Society convened a group of expert researchers and medical professionals to review the available science and make fact-based recommendations.

While research is underway to learn more about the specific experience of people with MS receiving a COVID-19 vaccination, data on the safety and effectiveness of COVID-19 vaccines in those with MS are limited. Our guidance is based on clinical trials of the general population and studies of other vaccines administered to people with MS. Our guidance will be updated as more is learned from scientific studies of the vaccines.

This guidance applies to people with MS ages 12 and older and only for the vaccines authorized or approved for use for their age in the United States, Pfizer BioNTech (Comirnaty), Moderna and Janssen/J&J.

People with MS should be vaccinated against COVID-19

The science has shown us that the COVID-19 vaccines are safe and effective. Like other medical decisions, the decision to get a vaccine is best made in partnership with your healthcare provider. Most people with relapsing and progressive forms of MS should be vaccinated. The risks of COVID-19 outweigh any potential risks from the vaccine. In addition, members of the same household and close contacts should also be vaccinated against COVID-19 when available to decrease the impact of the virus.

People with progressive MS, those who are older, those who have a higher level of physical disability, those with certain medical conditions (e.g., diabetes, high blood pressure, obesity, heart and lung disease, pregnancy), and Black and Hispanic populations are among groups with the highest risk for hospitalization due to COVID-19. Individuals in these high-risk groups are especially encouraged to get vaccinated.

If you’ve had COVID-19 and recovered, you should also get the vaccine. We don’t know how well protected people are after COVID-19 infection, or how long this protection might last. People who have had COVID-19 infection in the past can get infected again. . Even if you have been vaccinated you may need an additional dose or booster.

COVID-19 vaccines are safe for people with MS

None of the available vaccines contain live virus and the vaccines will not cause COVID-19. The vaccines are not likely to trigger an MS relapse or have any impact on long-term disease progression. The risk of getting COVID-19 far outweighs any risk of having an MS relapse from the vaccine. Learn more about how mRNA vaccines (Comirnaty and Moderna) and vector vaccines (J&J) work from the Centers for Disease Control and Prevention (CDC).
  
Any vaccine can cause side effects, including a fever. A fever can make your MS symptoms worse temporarily, but they should return to prior levels after the fever is gone. Even if you have side effects, it’s important to get the second dose of the vaccine for it to be effective. 

COVID-19 vaccines are safe to use with MS medications

Continue your disease modifying therapy (DMT) unless you are advised by your MS healthcare provider to stop or delay it. Stopping some DMTs abruptly can cause severe increase in disability with new lesions on MRI. Based on data from previous studies of other vaccines and DMTs, getting the COVID-19 vaccine while on any DMT is safe. Some DMTs may make the vaccine less effective but it will still provide some protection. For those taking Kesimpta, Lemtrada, Ocrevus, or Rituxan—you may consider coordinating the timing of your vaccine with the timing of your DMT dose. Work with your MS healthcare provider to determine the best schedule for you. Review our considerations of timing MS medications with these vaccines.

There is no preferred COVID-19 vaccine for those living with MS

Any of the three vaccines approved or authorized for your age are safe to get. There is no vaccine preference for those living with MS.

Staying safe following COVID-19 vaccination

The authorization of safe and effective vaccines for COVID-19 brings us one step closer to eliminating this pandemic. Whether you receive the Comirnaty, Moderna or J&J vaccine, it takes two weeks after being fully vaccinated before you are considered protected.

In addition to getting vaccinated, science shows that wearing a face mask, social distancing and washing your hands are the best ways to slow the spread of the virus. View CDC information on how to protect yourself and others even when you’ve been fully vaccinated. For people with MS, especially those in high-risk groups and those taking a DMT that might reduce the effectiveness of the vaccines, the safest approach is to continue wearing masks, practicing social distancing, and performing regular handwashing.

COVID-19 vaccines are safe to get at the same time as other vaccines

The CDC has determined it is safe for you to get the flu vaccine and other vaccines at the same time as the COVID-19 vaccine.
