In his 2003 State of the Union message, President Bush announced a $15 billion emergency program to treat and prevent AIDS in poor countries. It's called PEPFAR, the President's Emergency Program for AIDS Relief.
PEPFAR changed everything. Around 7 million people around the world now take antiviral drugs that suppress HIV to undetectable blood levels. That's about half of those who need it, based on the state of their declining immune systems.
