"OKLAHOMA CITY - Two University of Oklahoma scientists are starting
research that they hope will someday lead to the development of a
vaccine to combat the HIV virus, which causes AIDS.

The research to be performed by Mark Lang, an assistant professor of
microbiology and immunology at the OU Health Sciences Center, and
microbiologist John West will examine the basic aspects of the immune
system, rather than the complex aspects of the virus.

[...]

'There have been many promising candidates for a possible vaccine over
the years, but we've only been able to fully understand the immune
system's function in the last five years,' Lang said."

I doubt anyone "fully" understands the human immune system.  It's
interesting they claim this understanding has only recently been
achieved.  It makes me wonder what knowledge the discovery of HIV and
previous HIV drug development was based on.

"Lang said that in a best-case scenario, their research could lead to
a vaccine ready for use in about four years."

LOL.  And where have we heard that before?

This time the prediction may come true, though.  The HIV=AIDS theory
is running out of steam, and an HIV vaccine would provide the drug
companies with a nice stream of income.
