This study found that patients with multiple sclerosis (MS) receiving fingolimod treatment had a weaker humoral response to SARS-CoV-2 vaccines. The longer the treatment duration, the lower the antibody levels. Therefore, patients under fingolimod treatment may require closer monitoring for COVID-19.
Background: : The impact of disease-modifying treatments on humoral response induced by inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines is understudied. Methods: : We recruited 34 persons with multiple sclerosis (MS) under fingolimod treatment and 25 healthy individuals. Anti-SARS-CoV-2 spike IgG indices were measured by ELISA in sera of participants after CoronaVac vaccinations. Results: : Persons with MS displayed significantly lower antibody levels and seropositivity prevalence. Persons with MS with longer fingolimod treatment durations displayed lower anti-SARS-CoV-2 indices. Conclusion: : Our results support previous findings regarding humoral response impairing effect of fingolimod after vaccinations. Patients under fingolimod treatment may require closer monitoring for COVID-19.
