 AB    In an attempt to analyse the role of anti-envelope immunity in the
       protection of rhesus monkeys against an HIV-2 intravenous challenge,
       rhesus macaques were immunized twice with recombinant HIV-2 ROD vaccinia
       viruses (10(8) p.f.u. each) at days 0 and 30, followed by booster
       injections of purified HIV-2 proteins at months 8, 9, 15 and 27. One
       group of five macaques was immunized with the Gag, Pol, Vif and Nef
       antigens, whereas a second group received the same antigens with the
       addition of HIV-2 Env protein. Eight months after the last boost, the
       animals were challenged by intravenous injection of 100 AID50 of a
       monkey PBMC-grown stock of HIV-2 SBL. None of the animals was protected
       in spite of high humoral immune responses on day of challenge as
       determined by ELISA and Western Blot assays.
