AIDS virus: Image NIH

A medical research lab at Emory University in Georgia is developing an AIDS vaccine. Animal trials are encouraging – test subjects are developing AIDS antibodies in response to the vaccine.

The vaccine uses some genetic material from the AIDS virus, but not enough to actually get sick. After being exposed to this decoy virus, the body produces antibodies that can block AIDS, and also increases T cells that can kill the virus.
Researchers expect the vaccine could be available in three to four years.
