My research has contributed importantly to the understanding of the mechanisms by which HIV causes disease and to vaccine development efforts. HIV vaccine development efforts have come up shortA lab worker extracts DNA from samples for further tests at the AIDS Vaccine Design and Development Laboratory Dec. 1, 2008 in New York City. The rapidity of COVID-19 vaccine development and distribution puts the lack of an HIV vaccine in stark contrast. A fifth vaccine trial, the HVTN 702 trial, was ordered to confirm and extend the results of the RV144 trial. One approach researchers are trying in animal models in a couple of laboratories is to use herpes viruses as vectors to deliver the AIDS virus proteins.
