In brief: Unclear at this time
We do have a study of military personnel stating that those soldiers with lower vit d levels had a higher risk of ms, and another study of ms pts, who seemed to do better with higher blood levels.
However, causes of ms are far more complicated and involved. See no problem with supplementation, but talk to your pediatrician, as not clear re ideal vit level in kids (adults, aim for 50-60 ng/ml).

In brief: Vitamin D dose in MS
The recommended dose of vitamin d, 400 units is designed to guarantee that no ricketts appears.
The association with multiple sclerosis is not proven but is suggestive. You should discuss this with your pediatrician although a dose of 500-1000units probably is helpful.

In brief: Reduces relapses
High-dose vitamin d has shown promise in reducing relapses in relapsing-remitting ms.
However, there doesn't not seem to be any to prevent MS in someone who's going to get it. Hopefully, we'll know enough about it someday to treat it and/or find a cure.

In brief: Uncertain at present
There have been some reports of doses between 2000 -> 5000 iu per day may reduce the risk of multiple sclerosis.
These were small studies, were not double blind placebo controlled; the type of study the fda would require for approval. Yet one can draw some inferences, higher vit d levels are noted in people living in southern latitudes. 400iu is likely insufficient in the north, being indoors 5mo.
