Study: COVID vaccines do not cause multiple sclerosis outbreaks

“The information we have obtained should reassure patients with multiple sclerosis and convince them that vaccination against the new coronavirus does not lead to an exacerbation of the disease. This would allow them to be revaccinated if necessary in the event of a second outbreak,” says Professor Xavier Moisset of the University of Clermont-Avergne in France.

The professor and his team reached this conclusion by following the condition of more than 120,000 patients suffering from multiple sclerosis living in different regions of France, who received one or more injections of vaccines against the novel coronavirus during 2021 and 2022, as they followed their health and psychological condition in the first 45 days after receiving the vaccine or re-vaccination, and how many times the patients had to take corticosteroids to suppress the symptoms of the disease.

The results of this follow-up showed that vaccination against the novel coronavirus did not significantly affect the occurrence of new cases of multiple sclerosis, nor did it cause the symptoms of the disease to worsen in patients. According to the scientists, this indicates that vaccination against Covid-19 does not accelerate the development of multiple sclerosis.

But according to them, patients with active infections are an exception to this rule, in which case the symptoms of multiple sclerosis were exacerbated. Therefore, doctors should take this condition into account when re-vaccinating against the novel coronavirus.
