...miracle drugs. No wonder cures. No promises of panacea. The AIDS breakthrough announced Thursday in the journal Nature is a far more critical step: The decoding, if you will, of HIV's encryption key. For the first time, scientists have been able to snap X-ray pictures of what exactly happens when the virus that causes AIDS latches on to our immune cells -- and it's proving itself to be a more pernicious predator than anyone imagined. Dozens of spikes of protein stick out of its side, swathed in sugar so our antibodies won't be able to tell...
...course, now that we know the extent of HIV's nastiness we can get a lot closer to defeating it. The little hook that HIV uses to bind itself to cell receptor CCR5, for example, could be the virus' Achilles' heel. Blocking that hook may be the key to preventing HIV's ability to infect. "There's no question we're better off now than we were before," said Sodroski. "Before we were blind, now we are sighted." And that's a miracle in itself...
...AIDS experts, and they'll tell you the only way to control the epidemic is with a preventive vaccine. So why hasn't one been developed? It's not for lack of trying. Dozens of vaccines have worked in monkeys and against laboratory strains of HIV. But the virus mutates so quickly that no vaccine based on any particular strain is effective against them...

The new vaccine, AIDSVAX, developed by a company based in San Francisco called VaxGen, contains snippets of two strains of HIV yet has proved safe. It will be tested on healthy but high-risk subjects--5,000 North Americans and then, if Thailand approves, 2,500 Thais. The trials will take at least four years to complete...
