Table 2a. Peripheral blood mononuclear cells (PBMC) proliferation responses to VP1/2, VP2 and to tetanus toxoid (TT) among recently (C1–9) and remotely (S1–23) parvovirus B19 infected subjects compared with responses among non-immune (Ni 1–16) subjects.

Δcpm = antigen-specific counts per minute (cpm) minus background counts per minute (cpm). Background proliferation responses ranges were 499–3772 (mean 1436), 309–3277 (mean 1178) and 288–4752 (mean 1683) cpm among recently and remotely infected and seronegative subjects, respectively.
