This is insane!!!! In the latest development, U.S. government scientists say they have discovered three powerful antibodies, the strongest of which neutralizes 91% of HIV strains, more than any AIDS antibody yet discovered. They are now deploying the technique used to find those antibodies to identify antibodies to influenza viruses.

The HIV antibodies were discovered in the cells of a 60-year-old African-American gay man, known in the scientific literature as Donor 45, whose body made the antibodies naturally. The trick for scientists now is to develop a vaccine or other methods to make anyone’s body produce them as well.

Donor 45′s antibodies didn’t protect him from contracting HIV. That is likely because the virus had already taken hold before his body produced the antibodies. He is still alive, and when his blood was drawn, he had been living with HIV for 20 years.

While he has produced the most powerful HIV antibody yet discovered, researchers say they don’t know of anything special about his genes that would make him unique. It will take time to develop but this is one step closer for curing HIV.
