Researchers are hopeful they can develop an AIDS vaccine despite the recent, high-profile failures of two clinical trials, Health Day reports. But progress must be built on solid science and convincing preliminary results in animals. “There have been a lot of calls for a return to basic science,” one advocate said on World AIDS Day, “rather than testing candidates in people.”

An HIV vaccine is necessarily complicated: It must convey two types of immunity, act quickly in areas of the body where the virus quickly secures a beachhead by substituting DNA, and last a lifetime. Primate trials of earlier vaccines have been criticized for not protecting against the greatly various strains of the disease. Much promising research is underway. (More AIDS stories.)
