Google Flu Shot Locator
Google have collaborated with the U.S. Department for Health and Human Services to create a new feature for the U.S. which allows anyone to easily find where you can get both the seasonal and H1N1 flu vaccine.
Google say that the project has only just begun so initially many locations do not have flu shot data and some locations that are shown are currently out of stock. On loading the map Google will try to detect your location automatically. You can also enter your location into a search box.
After establishing your location the map shows locations where seasonal flu shots are available and where H1N1 flu shots can be had. The different locations are shown with red and blue map markers respectably.
In addition to this new map Google also provide the Google Flu Trends site to show the current search trends for 'flu' in 20 countries.
