Found: antibody ‘roadmap’ to Aids vaccine

Scientists on a quest for an antibody-based Aids vaccine said on Wednesday they found promising clues in the uncommonly “robust” natural immune response of a patient in Africa.
Studying blood samples over a three-year period after the person was infected, researchers were witness to a microscopic battle between the virus and antibodies - both evolving as they sought to gain the upper hand.
For the first time, scientists were able to follow the full chain of events leading to the patient naturally producing broadly neutralising antibodies (BnAbs) - so called because they attack different strains of the human immunodeficiency virus (HIV) that causes Aids.
