The President's advisor on Homeland Security John Brennan sent an email this morning addressing efforts to prepare our Nation for the coming flu season as the White House convene's an H1N1 Influenza Preparedness Summit.

The advice: "Wash your hands regularly. Take the necessary precautions to stay healthy and if you do get sick, stay home from work or school."

"This spring we were confronted with an outbreak of a troubling flu virus called 2009-H1N1. As the fall flu season approaches, it is critical that we reinvigorate our preparedness efforts across the country in order to mitigate the effects of this virus on our communities," stated a letter in the email signed by Kathleen Sebelius, Secretary of Health and Human Services, Janet Napolitano, Secretary of Homeland Security, and Arne Duncan, Secretary of Education.

The government will initiate a voluntary fall vaccination program against the 2009-H1N1 flu virus, "assuming we have a safe vaccine." It likely won't be ready before October.
