At T.C. Williams High School in Alexandria, nearly 600 people rolled up their sleeves for some of the years first flu shots.
Alexandria Health Department director Lisa Kaplowitz says the exercise is more than just a mass vaccination. It was also practice for when the H1N1 or swine flu vaccine is ready.
"Every event is a learning experience for us," Kaplowitz said. "We're really looking at what works and what doesn't work."
All the volunteers here were part of the Medical Reserve Corps a group founded in the immediate aftermath of the 9-11 attacks, and now sponsored by the Surgeon Generals office.
Congressman Jim Moran, and U.S. Health and Human Services Secretary Kathleen Sebelius, were also on hand to get their shots, along with Assistant Secretary for Health Dr. Howard Koh.
"With each vaccine given, that's one small shot for man, and one giant leap for public health," Koh quipped.
Bad jokes aside--Secretary Sebelius delivered some seriously good news about the H1N1 vaccine, which is expected to be ready in October.
This week, clinical trials showed adults will only have to take one dose for effective immunization.
