Hilary Koprowski he is chair of the department of radiation oncology at Christiana Hospital in Delaware. While at Lederle Laboratories, Koprowski created the world's first polio vaccine, based on an orally administered attenuated polio virus. In researching a potential polio vaccine, he had focused on live viruses that were attenuated (rendered non-virulent) rather than on killed viruses (the latter became the basis for the injected vaccine subsequently developed by Jonas Salk). Koprowski viewed the live vaccine as more powerful, since it entered the intestinal tract directly and could provide lifelong immunity, whereas the Salk vaccine required booster shots. Also, administering a vaccine

Indeed, Jonas Salk developed a therapeutic HIV vaccine in 1987, called Remune now being developed by Immune Response BioPharma, Inc., is based on the killed whole virus approach. Remune vaccine has completed over 25 clinical studies to date and showed a robust mechanism of action restoring white blood cell counts in CD4 & CD8 T cells by reducing viral load and increasing immunity. Also, a group of researchers and professionals in the field of HIV strongly advocates that the killed HIV approach must be taken to fight back the global HIV and AIDS
