Table 1:á HA Normalized Viruses Vary in Particle Number.á H1N1 and B viruses were titrated with 0.5% turkey red blood cells and H3N2 viruses were titrated with 1% guinea pig blood cells.á Particle counts were performed with virus titrated to a hemagglutination titer of 8 per 50 Ál and the VP/HAU calculated.
