News: Scientists discover antibody that kills 91 percent of HIV
Paving the way for an AIDS vaccine, scientists have discovered two potent antibodies, the strongest of which can neutralize 91 percent of HIV strains.
Researchers from the Vaccine Research Center at the National Institute of Allergy and Infectious Diseases discovered the antibodies in the cells of a 60-year-old African-American gay man, whose body made the antibodies naturally.
Last year, an HIV vaccine demonstrated roughly 30 percent efficacy. This new discovery triples the potency.
The United Nations has estimated that more than 33 million people had HIV in 2008. An estimated 2.7 million contracted the virus that year.
