Flu vaccine locations on Google Maps

Google has created a flu shot finder at www.google.com/flushot. To quote their Website,

The same tool will also be available shortly on www.flu.gov and the American Lung Association websites. It's important to note that this project is just beginning and we have not yet received information about flu shot clinics for many locations. In addition, many locations that are shown are currently out of stock. We launched this service now in order to help disseminate information about locations where vaccines are available, and also to make more vaccine providers aware of the project so that they can contribute.

Presently, they have about 20 states mapped, but the number will increase rapidly to cover the entire U.S. Today, you'll find results from chains such as Walgreens, CVS and PDX participants, such as Kmart, Duane Reade, WinnDixie and Giant Eagle.
