Study finds potential way to make an AIDS vaccine
Published in Saudi Press Agency on 03 - 09 - 2009


The discovery of immune
system particles that attack the AIDS virus may finally open a
way to make a vaccine that could protect people against the
deadly and incurable infection, Reuters quoted U.S. researchers
as saying today.
They used new technology to troll through the blood of
1,800 people infected with the AIDS virus and identified two
immune system compounds called antibodies that could neutralize
the virus.
And they found a new part of the virus that the antibodies
attack, offering a new way to design a vaccine, they reported
in the journal Science.
"So now we may have a better chance of designing a vaccine
that will elicit such broadly neutralizing antibodies, which we
think are key to successful vaccine development," said Dennis
Burton of The Scripps Research Institute in La Jolla,
California, who led the study.
"The findings themselves are an exciting advance toward the
goal of an effective AIDS vaccine because now we've got a new,
potentially better target on HIV to focus our efforts for
vaccine design," added Wayne Koff of the International AIDS
Vaccine Initiative, or IAVI, which sponsored the study.
Since the AIDS pandemic started in the early 1980s, more
than 25 million people globally have died from the virus. The
World Health Organization estimates that 33 million are
currently infected.
There is no cure, although a cocktail of drugs can help
keep the virus under control. Efforts to make a vaccine have
failed almost completely.
