Background.
An objective of the first efficacy trial of a candidate vaccine containing recombinant human immunodeficiency virus (HIV) type 1 envelope glycoprotein 120 (rgp120) antigens was to assess correlations between antibody responses to rgp120 and the incidence of HIV‐1 infection.
Results.
Peak antibody levels were significantly inversely correlated with HIV‐1 incidence. The relative risk (RR) of infection was 0.63 (95% confidence interval, 0.45–0.89) per log10 higher neutralization titer against HIV‐1MN, and the RRs of infection for second‐, third‐, and fourth‐quartile responses of antibody blocking of gp120 binding to soluble CD4 versus first‐quartile responses (the lowest responses) were 0.35, 0.28, and 0.22, respectively.
Conclusions.
Despite inducing a complex, robust immune response, the vaccine was unable to reduce the incidence of HIV‐1. Two interpretations of the correlative results are that the levels of antibodies (i) caused both an increased (low responders) and decreased (high responders) risk of HIV‐1 acquisition or (ii) represented a correlate of susceptibility to HIV‐1 but had no causal effect on susceptibility. Although the data cannot definitively discriminate between these 2 explanations, (ii) appears to be more likely.
