Flumist w/ clip? Anyone else have this?

Hello,

I took my sons ages 5 and 8 to get the flumist vaccine today. If side effects were to occur, how soon would they start? When my youngest gets head colds, he tends to wheeze so I want to watch him closely. Would side effects start within hours? days?

Also, I had the FluMist last week. The nurse did one of my nostrils and then removed a clip type thing before doing the other nostril. I did not notice the kid's nurse doing that (removing something before the second squirt.) Do you think it was done correctly? I made the kids sniff alot after the vaccine but then a friend told me they shouldn't do that. Is that true?

Thanks much.
