Researchers at the Harvard-affiliated Beth Israel Deaconess Medical Center recently developed a vaccine for rhesus monkeys that provides immunity against the Simian Immunodeficiency Virus (SIV), a virus found in monkeys that is analogous to HIV.
Rhesus monkeys that received this new vaccine had an 80 percent reduction in their chance of acquiring SIV upon future exposures, according to Dan H. Barouch, the lead author of the study and a professor at Harvard Medical School.
