Have you ever had chicken pox? If not you should ask your doctor if you should get the vaccine. Getting Chicken pox as an adult i would guess can be serious especially if you have MS. I would think your child may also need it, but ask the pediatrician and your neurologist to see what they say.

As Sarah says, if you’ve not already had chickenpox then you should certainly get vaccinated! I would also recommend getting the shingles vaccine, in case you haven’t already, as chickenpox and shingles are caused by the same virus.
