The following guidance for children and adolescents applies to vaccines currently authorized or approved for their age.

Children and adolescents aged 5-17 should be vaccinated against COVID-19

The science has shown that the COVID-19 vaccines are safe and effective. The American Academy of Pediatrics recommends COVID-19 vaccination for all children and adolescents 5 years of age and older who do not have contraindications for using COVID-19 vaccines available for their age. Vaccination of children and adolescents aged 5-17 brings us one step closer to ending this pandemic and is an additional layer of protection for the most vulnerable among us.

Children and adolescents are at risk of severe illness from COVID-19

Cases of COVID-19 infection are rising in children and adolescents. While most COVID-19 infections in children and adolescents are mild, some infections are severe or even fatal. In addition to health risks due to the COVID-19 infection itself, children and adolescents  are at risk for multisystem inflammatory syndrome in children (MIS-C) that can occur two to six weeks after the COVID-19 infection.

MIS-C is a condition that can occur after COVID-19 infection where different body parts can become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or gastrointestinal organs. MIS-C is serious, even deadly, although with prompt and often intensive care, most children and adolescents with MIS-C in the USA survive.

Children and adolescents with MS and related disorders should be vaccinated against COVID-19

The importance of COVID-19 vaccination for children and adolescents with MS and related disorders mirrors the advice for children and adolescents in general, as well as the advice for adults with MS. While there is no evidence to date that children and adolescents with MS experience more severe COVID-19 infection, nor that they are at higher risk for MIS-C due to COVID-19 compared to children and adolescents who do not have MS, vaccination is strongly encouraged. Like other medical decisions, the decision to get a vaccine is best made in partnership with your healthcare provider.

Risk for complications following COVID-19 infection is worse and more frequent than any potential complications from the vaccines

Studies have found more complications, like myocarditis, MIS-C and demyelinating events, after children and adolescents have COVID-19 infection than following COVID-19 vaccination. The benefits of vaccination outweigh any potential risks. Review Center for Disease Control and Prevention (CDC) guidance on vaccination for those who have had COVID-19 or MIS-C.

COVID-19 vaccines do not affect fertility

The American College of Obstetricians and Gynecologists are confident the COVID-19 vaccines do not affect fertility. They base this off the science of how the vaccines are made and a study has confirmed this. The American Academy of Pediatrics (AAP) also affirms that getting vaccinated against COVID-19 does not interfere with girls' or boys' future fertility. Watch this short video from the AAP to learn more.

The COVID-19 vaccines are not expected to cause MS or trigger an MS relapse

None of the available vaccines contain live virus and the vaccines will not cause COVID-19. There is nothing to indicate that the vaccines will cause MS. For children and adolescents with MS, 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.

Any vaccine can cause side effects, including a fever. A fever can make MS symptoms worse temporarily, but they should return to prior levels after the fever is gone. Even if side effects occur, it’s important to get the second dose of the mRNA vaccines for it to be effective. 

Children and adolescents who use medications to manage MS and related disorders should be vaccinated

Some medications used for MS and related disorders may affect responses to the vaccines. Coordinating the timing of vaccine administration with these DMTs may provide the best vaccine response. Work with your MS healthcare provider to determine the best schedule for you. Review our considerations of timing MS medications with these vaccines.

Family members of children and adolescents with MS should be vaccinated against COVID-19

Parents, siblings and those who live in the same house of a child or adolescent with MS should get vaccinated. Vaccination of an entire household reduces risk for COVID-19 transmission to persons in close contact with each other.
