Part of it is just that J.K. Rowling would rather sacrifice some realism and plausibility than have some characters die or get hurt. Is there any way that the Death Eaters shouldn't have killed all the D.A. during the 5th Book? Not those who got seperated from Harry at least... A group of Death Eaters with a vast arsenal of spells can't ever seem to get the words out before the Hogwarts children for the same reason, Rowling is attached to the good guys and doesn't want to face the facts that, in the world she herself constructed, the kids would be screwed and evil would prevail over good. But since she has all the power of an author, she gets to do as she pleases. She has Harry and others get hit by some spells, but none of them do lasting damage or have any specific malady, they're all sort of like getting kicked or punched...
Well, this is supposed to a children's storybook, after all....
