Antibody levels to the three viral antigens included in the 1999–2000 trivalent influenza vaccine (A/Sydney/5/97-like (H3N2), A/Beijing262/95-like (H1N1), and B/Yamanashi/16/98) were measured before and 4 weeks postvaccination in 43 lung transplant recipients and 21 healthy adult controls. The ability to develop protective antibody levels, a serological response, and the magnitude of change in levels were assessed. The humoral immune response to influenza vaccination was significantly lower in the transplant group for all three viral antigens. To A/Sydney, 95% of the control group and 40% of the transplant group developed protective levels (p=0.0009); to A/Beijing, 71% of the control group and 30% of the transplant group developed protective levels (p=0.004); and to B/Yamanashi, 48% of the control group and 19% of the transplant group developed protective levels (p=0.02). Those receiving cyclosporine had lower antibody responses when compared to those receiving tacrolimus (r=−0.3056, p=0.0463). The humoral immune response to influenza vaccination in lung transplant recipients is poor. Lung transplant recipients receiving cyclosporine may have a lower antibody response than those receiving tacrolimus. Alternative prevention strategies may be needed. ER -
