This research shows really promising results that could help prevent HIV infection in the future.
Cows have shown an "insane" and "mind-blowing" ability to tackle HIV which will help develop a vaccine, say US researchers. In a first for immunisation, the animals rapidly produced special types of antibody that can neutralise HIV. It is thought cows evolved a supreme immune defence due to their complex and bacteria-packed digestive system. The US National Institutes of Health said the findings were of "great interest". HIV is a slippery and nefarious opponent. It mutates so readily that every time a patient's immune system finds a way of attacking the virus, HIV shifts its appearance.
