TABLE 3.

Inhibition of HIV-1_JR-FL by plasma from RV144 subjects

^a The 0100 visits occurred prior to vaccination and allowed the collection of preimmune plasma samples. The 0800 visit occurred at 26 weeks after the initiation of vaccination, 2 weeks after the fourth vaccination (ALVAC-HIV twice, ALVAC-HIV + AIDSVAX-B/E twice).

^b The reciprocal anti-gp120 ELISA titers of the plasma samples were determined as described in Materials and Methods.

^c The titer of plasma that neutralized 50% of HIV-1_JR-FL or A-MLV infection was determined, as described in the Materials and Methods.
