The Salk vaccine had been 60–70% effective against PV1 (poliovirus type 1), over 90% effective against PV2 and PV3, and 94% effective against the development of bulbar polio.

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
