HIV vaccine approach nears human trial
San Diego Union-Tribune

For decades, scientists have struggled to develop vaccines to stop the spread of HIV. And for decades, the vaccines have failed. HIV mutates at a ferocious pace, outrunning the immune system’s antibodies.

Studies published Thursday demonstrate that the immune system can be accelerated so it’s primed and ready to block HIV infection.

The studies describe a multi-pronged approach to an HIV vaccine, each one demonstrating a component of the process.  Assembling all these components into a vaccine for humans is the final step. Testing could take place in about two years, the scientists say.
