Breakthrough That May Protect the World against HIV

April 05, 2010

Researchers at the International AIDS Vaccine Initiative and the Scripps Research Institute in LA Jolla, Ca, have discovered two new antibodies-produced by a minority of patients-that offer hope for an HIV vaccine. Because the new antibodies are "broadly neutralizing," they cripple many different strains of the deadly virus. Four other broadly neutralizing antibodies are known to exist, but the new weapons are more potent, latch on to their targets more easily, and are the first to have been isolated from patients in the developing world, where 95% of new AIDS cases occur. Researchers are now working on developing an active ingredient to put into a vaccine that would stimulate the production of these antibodies.
