In this photo made on Friday, Sept. 11, 2009, Alician Hudson, left, an employee in the medical office of the Bayer Corporation U.S. headquarters, receives an inoculation for influenza from company physicians assistant Tim Grimes, in the Pittsburgh suburb Robinson, Pa. The initial doses of the new swine flu vaccine will only be given to young people, pregnant women and other high-risk groups. Businesses will have to wait until those folks have been immunized to get swine flu vaccine for their workforce. Unless they jump through lots of hoops that vary from state by state to get it, creating confusion for companies, like Bayer, with offices all over the country. (AP Photo/Keith Srakocic)
