You want to avoid any of the vaccines that contain LIVE virus (such as the shingles) but the
flu shot is not one of those. The
flu MIST for
vaccine use does have the live virus and you want to avoid that.
The neurology world seems divided on whether the flu vaccine is important to us or not. MS occurs because our immune system is already over activity, and that may very well give us added protection. But if we do come down with the flu, i can guarantee you it will be miserable.
