 AB    To evaluate the effectiveness of vaccine protection from infected cells
       from another individual of the same species, vaccinated rhesus macaques
       (Macaca mulatta) were challenged with peripheral blood mononuclear cells
       from another animal diagnosed with acquired immune deficiency syndrome
       (AIDS). Half of the simian immunodeficiency virus (SIV)-vaccinated
       animals challenged were protected, whereas unprotected vaccinates
       progressed as rapidly to AIDS. Protection was unrelated to either total
       antibody titers to human cells, used in the production of the vaccine,
       to HLA antibodies or to virus neutralizing activity. However, analysis
       of the serotype of each animal revealed that all animals protected
       against cell-associated virus challenge were those which were SIV
       vaccinated and which shared a particular major histocompatibility
       complex (MHC) class I allele (Mamu-A26) with the donor of the infected
       cells. Cytotoxic T lymphocytes (CTL) specific for SIV envelope protein
       were detected in three of four protected animals vs. one of four
       unprotected animals, suggesting a possible role of MHC class
       I-restricted CTL in protection from infected blood cells. These findings
       have possible implications for the design of vaccines for intracellular
       pathogens such as human immunodeficiency virus (HIV).
