Good news on AIDS front

Again, from MSNBC :

Researchers said Thursday they have figured out how a rare antibody
sees past the disguises of the AIDS virus ? a finding that may lead
to a vaccine that will finally work against the killer microbe.

THE ANTIBODY, taken from a unusual patient whose body can resist the
virus, recognizes and attacks the human immunodeficiency virus,
unlike most of the body?s defenses.

?Nothing like this has ever been seen before,? Ian Wilson of The
Scripps Research Institute in La Jolla, Calif., who led the
research, said in a statement.

This is good news. A vaccine would stop the spread of the disease in the
Third World, where people without access to espensive medication simply
refuse to stop having sex with each other.
