In brief: In some situations

Research shows in most situations, taking vitamin c does not prevent colds, but in those who do extreme physical exertion or are exposed to cold temperatures it's a useful preventive- see http://www.
Ncbi.Nlm.Nih.Gov/pubmed/15495002?Dopt=abstrct . Studies show vit c reduces duration of cold symptoms. High doses at onset may be especially helpful- see http://www.Vitamincfoundation.Org/surefire.Shtml.

In brief: No

Any benefit from vitamin c comes at high doses.
Imo, it is not worth the trouble.
