title: Prevention of HIV-2 and SIVSM infection in cynomolgus monkeys by active or passive immunization.
abstract: We have established experimental infection with HIV-2 and SIVsm in cynomolgus monkeys and successfully used these models for vaccine experiments. Protection against homologous HIV-2 infection was demonstrated in two of two monkeys immunized with a Triton-X100-treated whole HIV-2SBL-6669 vaccine in incomplete Freund's adjuvant and in 2 of 4 monkeys immunized with a formalin-inactivated whole HIV-2 vaccine in RIBI adjuvant. Monkeys preinfected with a live poorly replicating HIV-2 strain were shown to develop cross-protection against SIV-induced disease. We have shown also that HIV-2 and SIVsm infection in cynomolgus monkeys can be prevented by passive immunization. These results raise hope for effective immunization against HIV infections in humans.
