Dr Jonathan Fielding, Director of the County of Los Angeles Public Health, shows the new 'FluMist' nasal spray vaccine for the H1N1 virus (known as Swine Flu) as he outlines it's distribution plan at a press conference in Los Angeles on October 8, 2009. The United States began a massive campaign to administer 250 million vaccinations by year's end and health care workers, who are among the most at-risk groups according to the CDC, are at the head of the line for the vaccine. The first H1N1 vaccinations were administered to doctors, nurses, first responders and other health personnel in the states of Illinois, Indiana and Tennessee. But they got a squirt up the nose, not a shot in the arm, as the nasal spray vaccine has rolled off production lines ahead of the injectable variety. Getty Images logo Getty Images 2 months ago
