After users enter a ZIP code or town, the tool displays color-coded syringes on a map.  Pink syringes indicate the availability of seasonal flu vaccinations, blue syringes represent the availability of swine Flu H1N1 flu vaccinations – pink and blue syringes mean both vaccinations are available.

The American Lung Association and HHS’s flu.gov collaborators also worked on the project.

The flu shot finder includes data for about 20 states so far, and Google says they are curretly updating the map with all US states. No word on if the map will be updated to North America or worldwide.
