This Is MS Multiple Sclerosis Knowledge & Support Community

Patients with multiple sclerosis who plan to travel to areas where yellow fever is endemic need to think carefully about whether to be vaccinated against the disease, researchers warned in a report on their small study.

During a five-week at-risk period after vaccination, the annual rate of MS exacerbation was 8.57, compared with a rate of 0.67 after the end of the risk period, according to Mauricio F.

increased by infection and further increased
by dietary protein ingestion after infection

and thats immunization

So are there any folks out there with MS who have had the yellow fever vaccine? Did you have a relapse?
