( CNN ) -- With the promise of coming AIDS vaccines , former President Bill Clinton urged the world 's nations Monday not to give up on funding to prevent a calamity . Overall support for global AIDS efforts from donor nations flattened amid 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 Program 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 have 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 , '' he said . After years of disappointment , researchers have finally found a potential basis for an HIV vaccine . Scientists at the National Institute of Allergy and Infectious Diseases say they have discovered three human antibodies that neutralize more than 90 percent of the current circulating HIV-1 strains . `` There is a preliminary indication that sometime in the next two to three months , we 'll get some reports on vaccine tests , which are very hopeful for the quick development on a vaccine that actually works , '' Clinton said . `` Meanwhile , we know that if you start people on the medicine not when they have full-blown AIDS , but as soon as their so-called CD4 blood count drops below a certain amount , it can prevent 90 percent of AIDS , '' he said . `` That 's about as good as a vaccine . It 's not 100 percent , but if we could just do that , this whole epidemic would be in a different place in five years . '' When asked about the affordability of such medicine in poor countries , Clinton said cost should not be an issue . `` In most places , the donors are providing this medicine , '' he said . `` You should be able to get that help right now because I have negotiated great contracts for this medicine all over the world . And if you ca n't , you need to get in touch with us directly , and I 'll try to make sure it happens , because in any poor country , people should n't have to pay anything for it . '' HIV/AIDS is the world 's leading infectious killer , according to the World Health Organization . The disease accounted for an estimated 2 million deaths in 2008 , and more than 33 million people are living with the disease worldwide . The researchers say the findings put them one step closer to their goal , and among their next steps are plans to make sure other people -- not just those infected with HIV -- can create these types of antibodies . They also want to figure out how to be able to potentially mass-produce more `` broadly neutralizing '' antibodies to block nearly all HIV strains in the future . Clinton said the United States has increased contributions to AIDS programs , but not as much as hoped . `` It 's not enough , but there are serious budget constraints in the congressional process , '' he said . `` I think the president did what he thought was the best he could do . '' Clinton said that money must be spent to `` make good things happen . To give people a chance to live their dreams . '' `` We should n't be penny wise and pound foolish in an interdependent world where we worry all the time about terrorism , we worry all the time about violence , '' he said . `` When President Bush 's and America 's approval went way down all over the world because of the Iraq war , '' he said , `` there were three places where it did n't go down : in India , where we made a deal for peaceful nuclear cooperation ; in central and eastern Europe , where we continued my policy to expand NATO ; and in the 10 countries of southern and eastern Africa where PEPFAR [ the U.S. President 's Emergency Plan for AIDS Relief ] was concentrated and the highest AIDS rates were . `` Did they agree with President Bush 's Iraq policy ? No . ... They thought he and the United States cared whether their children lived or died . '' Clinton said nations have many ways to help . `` I would like to see all the other countries that started their cutback a year before we did do the same kind of soul-searching and ask themselves what 's going to happen , '' he said . `` I also think that since the economy 's coming back , it may be that everybody should consider making clear that over a two- to three-year period , they will give three years ' worth of money . ... There 's a thousand ways to work this out . ''
