We were told that there is a risk, but that it is minimal. Brandi is right- those with CF will be exposed to MANY people who have had the mist and there's nothing that can be done about it. It makes sense that if we are worried about it that controlling what we CAN makes sense (shots for the family) since there is so much more direct contact with them. However, the risk is quite low (something like less than 2%.) It's nothing like risk of exposure when someone is actually sick with the flu, even if they do catch a cold, etc, and as always, proper hand hygiene, covering cough, etc will be of enormous benefit to avoid transmitting ANY contagious illness.
