Actually, it has been shown to be more effective, especially in children. From the FDA:
"In clinical trials, FluMist was evaluated in 20,228 individuals, including over 10,000 children 5-17 years old. FluMist was effective in preventing influenza in approximately 87 percent of children in the trial.
In children under age five, two studies compared FluMist to placebo (no vaccine). Both studies demonstrated the vaccines effectiveness in preventing influenza illness. A third study compared FluMist to an inactivated or "killed" seasonal influenza vaccine shot. The results showed that there were 53 cases of influenza disease among 3,900 children who received FluMist compared to 93 cases among the same number of children who received an inactivated or "killed" seasonal influenza vaccine shot.
In adults (ages 18-49 years), there were fewer upper respiratory illnesses with fever and fewer severe illnesses with fever in those who received FluMist versus those who received placebo."
And no, I don't work for FluMist or anything.

I just puzzle at how many people line up for pain and possibly less effectiveness. I figured maybe people just didn't know about FluMist since it isn't advertised very much.
For me, it's a God-send. You'd have to convince me death was imminent before you'd even get a needle in the same room with me... no way I'd get a flu shot for the heck of it!

I wish all vaccines were nasal like this one!
