I'm thinking not. 
My friend's 1 year old son got croup, and she panicked and took him to the ER. The doctor gave him steroids and told her to use humidifier, steamy shower, out in the cold, blah blah blah.
Then he tells her that his croup shouldn't get that bad since he had the flu shot. WTF? She was acting like it was so fantastic that they had just gotten the first half of the flu shot a week or so earlier, and planned to get a second dose very soon. After he told her this, about the flu shot making croup less severe, she was saying she'd DEFINITELY get that second dose.
Now, she's very pro-vaccine, pro-doctor, so she'd get the shot anyway. But is there ANY truth to the flu vax having an effect on croup? I couldn't find anything, and basically think the ER doc gave her a BS story.
