I've heard that there is a new vaccine against the flu. What is it and how does it work?

The new vaccine is called FluMist, and it is a nasal spray vaccine that contains a live, weakened form of the influenza virus. It is designed to stimulate your immune system to produce antibodies against the flu virus. The vaccine is given as a nasal spray, which helps the body to absorb the vaccine more easily than if you were vaccinated with an injection.
