Americans who are frustrated with shortages of swine flu vaccine place slightly more blame on drug companies than the federal government, a USA Today/Gallup Poll. With swine flu widespread in 48 states and pediatric deaths mounting, only 5% of respondents have received the vaccine since it became available in October, the poll shows. Fifty-eight percent place a great deal or moderate amount of the blame for the lack of vaccine on the federal government, the poll shows, and 62% blame drug companies.
