Less screaming at the doctor's office or pharmacy now that the CDC thinks it oks for kids 2-8 to get the inhaled flu vaccine instead of getting a shot. Honestly, who enjoys having a metal tube inserted into one's skin? Who looks forward to that senation of alcohol chilling the skin as its rubbed on and then possibly fanned on the arm? It's supposed to be better in terms of efficacy.
Minutia from the CDC memo, back in 2010 almost everyone at least 6 months old was asked to get a flu vaccine.
