This is interesting since we just talked about the flu vaccine versus the nasal spray, FluMist. The FDA just approved the aerosolized vaccine for children as young as 2. Formerly, children younger than 5 could only receive a flu shot. I guess this is good for all those kids who hate shots and go screaming down the hall and/or cling to the underside of a table (like I did when I was little haha). But, according to what Professor Siegel said, I guess it could be annoying for an hour or so.
