Studies on the specificity of the vaccine effect elicited by inactivated simian immunodeficiency virus.
Inactivated, partially purified simian immunodeficiency virus (SIVmac) protected macaques from intravenous challenge with homologous and heterologous strains of SIV that had been grown on human cells but no protection against challenge with monkey peripheral blood mononuclear cell-grown SIVmac was afforded. Human immunodeficiency virus type 1 prepared in an analogous way to the SIVmac vaccine on the C8166 human T cell line protected macaques against challenge with human cell-grown SIVmac. These results suggest that protection may be mediated by xenoimmunization with the vaccine cell substrate proteins. All vaccinated macaques had anti-cell antibodies. Major reactivity to MHC class I antigens was found as well as to a 70-kD protein detectable only under nonreducing conditions.
