ST. LOUIS -Hundreds of Americans are lining up for experimental swine flu shots in eight U.S. cities in a race to get a new vaccine out this fall before the new flu virus sweeps the country.
Sharon Frey, who is leading the government-funded testing at Saint Louis University, said scientists have been working late nights and weekends to organize the studies and recruit volunteers.
The government says the first vaccine doses will be available by fall.
The studies of 2,800 people under way will test the safety and effectiveness of vaccines developed by drug makers.
The other study sites are Baylor College of Medicine, Children's Hospital Medical Center in Cincinnati, Emory University, Group Health Cooperative in Seattle, University of Iowa, University of Maryland School of Medicine, and Vanderbilt University.
