Evaluation of willingness to obtain of Covid 19 vaccine in patients with multiple sclerosis.

Introduction: Assessing vaccine willingness and understanding sources of vaccine hesitancy in individuals with multiple sclerosis (MS) helps healthcare providers approach patients more effectively while respecting their autonomy to encourage coronavirus disease 2019 (COVID-19) vaccination.

Materials and methods: A descriptive-analytical cross-sectional study using a researcher-made checklist was conducted on MS patients referred to Neshat Clinic of Hamadan during the years 2020-2021. The checklist contained questions about demographic information, MS phenotype, duration of illness, expanded disability status scale (EDSS) score, and COVID-19 vaccination status. The expanded disability status scale (EDSS) is the most commonly used instrument for measuring disability in patients with multiple sclerosis (MS). The EDSS scale ranges from 0 to 10 in increments of 0.5 units, denoting advanced points of disability.

Results: Based on the results, 20 individuals (10%) were in the vaccine non-acceptance group, while 181 individuals (90%) were in the vaccine acceptance group. A significant number of relapsing and remitting (RR) type MS patients (90.7%) and all primary progressive (PP) type MS patients (100%) accepted the vaccine. In comparison, vaccine non-acceptance in the secondary progressive (SP) group was relatively higher (20.7%) compared to other types of MS, and this difference was significant (P < 0.05). Additionally, there was a statistically significant relationship between the history of COVID-19 and vaccine acceptance (P < 0.05).

Conclusion: The study results demonstrated a high rate of COVID-19 vaccine acceptance among MS patients. MS phenotype, previous infection experiences, and other influences allow for COVID-19 vaccine acceptance among MS patients. This information can improve health programs and communication strategies for COVID-19 and future possible infectious disease vaccination in individuals with MS.
