borderline significancep = 0.08
At 2 wpc, env-specific IgGs were significantly lower in controls when compared to immunized monkeys in all groups (p < 0.03); at subsequent points in time (4 and 8 wpc) controls showed minor differences with p-values being attenuated to borderline significance (p = 0.08 and p = 0.06, respectively) and the IgG-titres reached a maximum level of 58.5 MFI ± 39.2 (median: 50.3) at 12 wpc.
