Abstract

The continuous rapid genetic and antigenic evolution of H5 subtype influenza viruses has major implications for the sensitivity of serological assays and can limit the efficacy of pre-pandemic human vaccines and the ability to undertake effective sero-surveillance in susceptible populations. A panel of serum samples collected from the Italian population between 1992 and 2007 and previously found to be positive for antibodies against H5N1 as determined by SRH, were evaluated using pseudotype based neutralisation assays in combination with haemagglutination-inhibition assays using a clade 1 and a clade 2 H5N1 serological antigen. From the results obtained it can be concluded that the pseudotype assay measures cross-reactive antibody responses that are not picked up with the HI assay. Both assays measure antibodies with different (functional) specificities contributing to a comprehensive analysis of humoral immunity to influenza viruses.
