Since the swine flu outbreak began last spring and spread to more than 100 countries researchers have been working around the clock to come up with an effective shot in sufficient quantities before too many people got sick. In the U.S., the H1N1 swine flu has infected more than a million people and caused about 600 deaths. Since the start of the school year, it's been detected in all 50 states and is widespread in the Southeast, plus Maryland, Oklahoma, Arizona, and Alaska. Last week, the National Institutes of Health announced that clinical trials show that just one dose will be effective for most adults who need it, ensuring that everyone who wants one, can get a shot.
