Antibody shields monkeys from ‘HIV’ for months: study

Antibody shields monkeys from 'HIV' for months: studyJust one shot of a lab-produced antibody protected macaques against a sort of monkey HIV for nearly six months, said a study Wednesday into a potential vaccine alternative. Exposed to simian HIV (SHIV) once a week, non-treated monkeys contracted the virus after just three weeks on average, the researchers said, whereas the trial monkeys remained virus-free for up to 23 weeks. In human populations at high risk of contracting the AIDS-causing virus, such protection, even temporary, "could have a profound impact on virus transmission," the team of German and US-based researchers reported in the journal Nature.
