Now that flu season is in full swing, people are scrambling for a vaccine. And the rush is even more hectic because of the H1N1 scare. To help with the high demand, Google Inc. has launched a flu shot finder at www.google.com/flushot. It provides users with the locations of clinics that offer seasonal and H1N1 vaccines. The site works like Google Maps. Enter a ZIP Code or the name of a city and the closest sites will appear. Clinics offering H1N1 shots are blue. Those offering seasonal shots are red. And those providing both are half red and half blue. Google worked on the feature in collaboration with the Centers for Disease Control and Prevention as well as the Department of Health and Human Services. The locater eventually will be linked on www.flu.gov and the American Lung Association Web site. But be aware that many locations that are shown on the site may be out of stock, Google said. So make sure you call in advance.
