London, February 28 : An international group of American and British scientists have found that the human immunodeficiency virus (HIV) has the ability to adapt to the body''s defence system, which suggests that any successful AIDS vaccine must keep pace with the ever-changing immunological profile of the virus.
Researchers at the University of Alabama at Birmingham (UAB) and the University of Oxford in England conducted a study that showed HIV adapts by spelling out at least
14 different "escape mutations" that help keep it alive after it interacts genetically with immunity molecules that normally attack the virus.
The researchers revealed that they analysed genetic data from more than 2,800 HIV-infected patients on five continents.
