An experimental vaccine appears to be working on monkeys with an animal version of the AIDS virus.
Researchers say the vaccine being developed by a Johnson & Johnson-owned company worked on most monkeys tested.
Animals given the vaccine were up to 83-percent less likely to get Simian Immunodeficiency Virus or SIV. That's a monkey form of AIDS.
Researchers say other vaccines have helped control the virus' impact in AIDS-infected monkeys.
However, they say this vaccine is the first to actually stop an animal from becoming infected.
Researchers are planning human testing.
The study on the vaccine is posted on nature.com
