Experimental HIV vaccine successfully elicits broadly neutralizing antibodies to the virus

(Scripps Research Institute) An experimental HIV vaccine developed by scientists at Scripps Research and the nonprofit vaccine research organization IAVI has reached an important milestone by eliciting antibodies that can neutralize a wide variety of HIV strains. The tests, in rabbits, showed that these "broadly neutralizing" antibodies targeted at least two critical sites on the virus. Researchers widely assume that a vaccine must elicit bnAbs to multiple sites on HIV if it is to provide robust...
