Most years at least one of the influenza virus subtypes changes. The results of this change are viruses and virus combinations against which previous years' vaccine formulas offer little protection. A government agency monitors the flu to identify and to track the most common virus variations. Based on data collected from previous years and on predictions about which virus strains will be most prominent in the coming year, this agency decides what subtypes of killed virus to include in the current influenza vaccine.

Yes it is and thanks for that too. Glad you're helping and participating. I'm learning something here. To me this is what it's supposed to be about.

BTW...that last link is a little outdated...Intranasal (nose spray) flu vaccine has been under development for over 20 years but is not yet licensed in the United States.
