9 , bottom row); these differences were significant for all groups including the LVS Δ capB vector in experiment 1 (ranging between P < 0.05 to P < 0.01) and for all but the parental vector and one vaccine in experiment 2 (ranging from P < 0.05 to P < 0.0001); combining all LVS Δ capB and r LVS Δ capB /Bp vaccines, the increase in antibody to HI Bp82 was highly significant ( P = 0.0002 and P < 0.0001 by two-tailed t test in experiments 1 and 2, respectively).
