At the conclusion of Thursday’s sessions at the 20th International AIDS Conference (AIDS 2014Exit Disclaimer) in Melbourne, Australia, we spoke again with Dr. Carl Dieffenbach from NIH/NIAID by Dr. Kenneth Mayer of Boston’s Fenway Health and Harvard Medical School. In addition to effectively deploying those tools, Dr. Mayer and others at the conference called for advancing research underway to develop new or better tools, including an HIV vaccine and vaginal ring to prevent HIV transmission. Additionally, researchers are studying novel means of delivering PrEP—such as injectables, implantables, and patches that would make PrEP easier to use and increase adherence. (Read more about vaccines and microbicides.)

Watch Dr. Dieffenbach’s remarks above. Check back tomorrow for Dr. Dieffenbach’s final conference observation from AIDS 2014.
