2. There is a doubt whether yellow fever vaccine can be given to patients suffering from multiple sclerosis, who are using disease modifying immunotherapies. There is a concern that yellow fever vaccine can trigger a relapse of multiple sclerosis.

3. A recent study assessed the risk of relapsing-remitting multiple sclerosis worsening after yellow fever vaccine.
One-year annualized relapse rate and time to first relapse were similar among the vaccinated and unvaccinated groups.
