New Vaccine Protects Monkeys Against Primate Version of HIV

Researchers have developed a vaccine that protects Rhesus monkeys against SIV, the simian version of the human immunodeficiency virus that causes AIDS in humans. Scientists say the experiment could lead to improved treatments for AIDS, and speed development of an effective HIV vaccine.

Building on the results of a large experimental AIDS-vaccine trial in Thailand reported in 2009, researchers developed a two-stage vaccine made up of proteins from the simian immunodeficiency virus, or SIV, that protects a significant percentage of Rhesus macaques against the disease. SIV is a model for HIV because the human virus cannot infect monkeys.

Colonel Nelson Michael is a molecular virologist with the U.S Military HIV Research Program at the Walter Reed Army Institute, and senior author of the research.

“We have now very good evidence, with new generation vaccines that we are seeing, the kinds of promising results in animals that would propel us to spend significant resources to test these vaccines in humans, which is what we are planning to do,” said Michael.
