Yes. Passage of the attenuated flu virus in FluMist is quite unusual and not only not harmful if it does occur, but may be beneficial.
My daughter's nose is always stuffy, but I would like her to get the flumist. Can I give her a nasal spray decongestant before getting the flumist?
No need. There is no contraindication to getting the flumist with a stuffy nose. Just have your daughter blow her nose before the flumist.
