Figure 6

Three expected ratios (80%, 100% and 120%) of the HA from each influenza reference strain in the 2010–2011 vaccine (A) A/California/7/2009(H1N1), (B) A/Victoria/210/2009(H3N2) and (C) B/Brisbane/60/2008(Victoria-like). Vaccine samples with known amounts of HA (pre-determined by SRID) were employed in spiking and recovery assays using strain-specific rabbit antibodies. Each sample was tested in triplicate. Data are shown as mean ± SD from two experiments (see also Figure S3). For HA concentrations obtained from each strain at each ratio see Table 3.
