Testing of New HIV Vaccine Carries Hopes of a Breakthrough

A clinical trial of an experimental vaccine against HIV that just began in South Africa is raising new hopes of making new strides against the disease. The trial follows recent news of tests in animals that suggest the vaccine, in combination with an innate immune stimulant may be able to put infected patients into remission. We spoke to Colonel Nelson Michael, director of the U.S. Military HIV Research Program at the Walter Reed Army Institute of Research, about the new trial, how this vaccine builds on what was learned from a clinical trial in Thailand from an earlier version of the vaccine, and why there’s hope of related work moving researchers towards a functional cure for the disease that could free patients from the need for antiretroviral therapy for extended periods.
