The flu vaccine studied was FluMist, which is made of a live, weakened virus. It's only available right now to kids over 5, but is being studied in children 6 months to 5 years of age.

And there's only a 1 percent increased risk (compared to the flu shot) that babies and toddlers could have asthma-like wheezing in the weeks after getting the spray.
