The weather is finally turning cooler and for a lot of people that means it's time to get a flu shot. But by this time next year, it may not involve a shot at all.

It's called FluMist and it's a nasal spray manufactured by AstraZeneca that can be administered at home. CBS Correspondent Alex Tin joined KRLD to talk about it.
