Despite efforts of scientists all over the world there has been no cure for AIDS. The U. S. government is motivating scientists to find a cure against HIV. The need to find a new cure for this deadly disease has been intensified after Merck & Co.'s Ad5 vaccine, the most promising effort to date that flopped in 2007. HIV virus affects 2.7 million new patients each year

David Margolis, a doctor at the University of North Carolina in Chapel Hill, who has been working for years to cure HIV, said that if the vaccine had worked, I don't think any of this would be happening. Getting so close to an effective vaccine and then having to start from scratch again has made people wisely step back and re-evaluate the whole playing field of options.

There has been proposal of a government-funded effort to discover how HIV persists in the body even after powerful drugs drive the virus below levels detectable by conventional means by Margolis, along with researchers at Merck & Co., Johnson & Johnson, Harvard, Johns Hopkins University and other institutions.
