Inhibitory function of antibody against DBL-TH-erythrocyte binding was persistent post-infection. The prevalence and stability of inhibitory antibodies against (a) DBL-TH2, (b) -TH4, (c) -TH5 and (d) -TH9 binding was measured at 3 m, 9 m and 12 m post-infection. The prevalence of high inhibition was shown as %HI.
