Measuring T cell immunity to influenza vaccination in children after haemopoietic stem cell transplantation

Year: 2004

Type: article

Abstract: Quantitative assessment of immunogen-specific T cell responses may provide a meaningful surrogate marker of functional immunity in patients following haemopoietic stem cell transplantation (HSCT). We developed a flow-cytometric assay to quantify antigen-specific T cell immunity to influenza-A and studied the T cell response to influenza vaccination in five children, 3-21 months post-HSCT. All patients showed an increase in influenza-A-specific CD4(+) immunity following vaccination while none had a detectable IgG response to the vaccine. This assay proved sufficiently sensitive to evaluate changes in T cell memory in immunocompromised individuals and could be used to better characterize post-HSCT immune reconstitution.
