Discovery May Pave Way to AIDS Vaccine

National Institutes of Health (NIH) scientists now have "proof" that the search for an AIDS vaccine can succeed.

In the blood of an HIV infected person, the researchers discovered two powerful antibodies that neutralize 91% of HIV strains.

"The discoveries we have made may overcome the limitations that have long stymied antibody-based HIV vaccine design," Peter D. Kwong, PhD, chief of structural biology at the NIH Vaccine Research Center, says in a news release.
