What's this science children's book from the early 1990s?

I remember reading a book between like 1990 and 1992 about the immune system and antibodies. The illustration was nutcracker looking soldiers. It was by either Funk & Wagnalls, Scholastic or maybe TIME. Does anyone have any idea what book this is or where I can still buy it? I've searched ebay and Amazon with no success.
