(CNN) - With the promise of coming AIDS vaccines, former President Bill Clinton urged fellow nations Monday not to give up on funding to prevent a calamity.
Overall support for global AIDS efforts from donor nations flattened in the midst of last year's global economic crisis, according to a recent analysis of 2009 funding levels from the Kaiser Family Foundation and the Joint United Nations Programme on HIV/AIDS.
Clinton spoke with CNN's Becky Anderson at the International AIDS Conference in Vienna, Austria.
"If we all do this, the consequences will be calamitous and you'll spend more money later," Clinton said, referring to reduced donations. "You'll start having large numbers of people dying again, you'll more political instability, more economic collapse, and it's going to cost us more money later. So it's not only going to be a humanitarian crisis, you'll pay now or pay later. So if it's at all, possible hang in there," Clinton said.
