Some good news for a change

The good news is scientists may have identified the Achilles heel in the HIV.

Scientists have captured an image of the AIDS virus in a biological handshake with the immune cells it attacks, and said today they hope this can help lead to a better vaccine against the incurable disease.

They pinpointed a place on the outside of the human immunodeficiency virus that could be vulnerable to antibodies that could block it from infecting human cells.

US National Institutes of Health researcher Peter Kwong said the study, published in the journal Nature, may reveal HIV's long-sought "site of vulnerability" that can be targeted with a vaccine aimed at preventing initial infection.

"Having that site and knowing that you can make antibodies against it means that a vaccine is possible," Kwong said in a telephone interview.

"It doesn't say we've gotten there. But it's taken it off the list from an impossible dream and converted it to something that is a (mere) technical barrier."

Experts agree that a vaccine is the only hope of stopping the pandemic of AIDS, which has killed more than 25 million people since it was first recognized in 1981. About 40 million people now live with HIV, with sub-Saharan Africa hardest hit.

Note: I did the research and it appears HIV and AIDS are acceptably interchangeable terms even though they aren't quite the same thing.
