Broadly neutralizing antibodies

Patent Pending By 2006, researchers had identified a few so-called "broadly neutralizing antibodies" (bNAbs) that worked on multiple HIV strains. They analyzed 1800 blood samples from HIV-infected people from Africa, South Asia and the Anglosphere. They individually probed 30,000 of one woman's antibody-producing B cells and isolated two that were able to stop more than 70% of 162 divergent HIV strains from establishing an infection. Since 2009, researchers have identified more than 50 HIV bNAbs.
