Out of an abundance of caution, I have also asked Congress for $1.5 billion if it is needed to purchase additional antivirals, emergency equipment, and the development of a vaccine that can prevent this virus as we prepare for the next flu season in the fall.

The Recovery Act that Congress enacted in February also included expansions of community health centers, a dramatic increase in the training of health care workers and nurses, and $300 million for the development and deployment of vaccines - all of which will help us meet this threat.

Finally, thanks to the work that the last administration and Congress did to prepare for a possible avian flu pandemic in 2005, states and the federal government have fully operable influenza readiness plans and are better prepared to deal with such a challenge than ever before.

It is my greatest hope and prayer that all of these precautions and preparations prove unnecessary. But because we have it within our power to limit the potential damage of this virus, we have a solemn and urgent responsibility to take the necessary steps. I would sooner take action now than hesitate and face graver consequences later. I have no higher priority as President of the United States than the safety and security of the American people, and I will do whatever is necessary to protect this country. So I want to thank every American for their patience and understanding during this developing challenge, and I promise that this government will continue speaking clearly and honestly about the steps we're taking to meet it.

Thank you.
