Scientists Expose HIV Weak Spot

Scientists have shown what happens when an infection-fighting antibody attacks a gap in HIV’s formidable defences. The National Institute of Allergy and Infectious Diseases-led team say the work could aid HIV vaccine development. They have published an atomic-level image in Nature showing the antibody, b12, attacking part of a protein on surface of the virus. HIV avoids attack by constantly mutating, but this protein segment is a weak spot because it remains stable
