If you get FluMist, you don't get the real flu, so you won't be coughing and spreading the virus everywhere. Even if I catch the FluMist strain from you, it can't get in my lungs so I won't get the real flu either. We will, however, get immunity against the wild strain.
Other live virus vaccines include MMR, yellow fever, the oral polio vaccine, varicella, and both rotavirus vaccines (1, 2).
Thanks for the info. That makes it easier to understand.
